here you go brobee.

its basically a mossberg with a crossbolt safety instead of the one on the rear (tang?)

i think they allready do have versions of a stand alone M-203 which uses a folding stock. like a over the top model that choate makes for shotguns. ill look it up some more!

can you get 203 rounds in Canada? if so what type an how much per round? an would it be illegal to ship/drive across borders woth this kind of ammo? if it is then forget it!!!! but if it isnt then ........Cool!.......

i would like to get ahold of some TPT. its the training rounds the military uses. its just a marking powder in the shell an is fired from the primer no powder. there very fun though!!
 
Looks interesting...

.... and a possible option for future mods for my 870.

Keep the posts updated on production/cost of units. How close are you to production or pre-production testing of commercially cast units?
 
Hello!

willyjixx: 203 rounds are available here in Canada, however as I don't yet have a launcher I have not put much homework into what flavors are available (I think I can state with some certainty though that HE is out...:(!). I believe they are also pretty expensive, like $25/round. If this were true, it would be my intent to spin my own casings and fabricate my own ammunition.

Take care...

Hello All!

Progress Update: The master injection mold is about a week and a half away from being complete with pre-production testing of the commercially cast units scheduled to take place the last week of July. This testing will entail two or three units, a thourough measurement sessionfor each one, mounting to all 6 of my 870 receivers to test for fit (amazingly enough, they are all slightly more different dimensionally than one might imagine), and then 250 rounds of buck/slug for each adapter. I'll also have to do some testing on the finish I'm planning to use, but I don't think that this would hold up proceeding with the casting run. I should be able to get all of this testing done in a weekend and have the main production run underway by the first week in August.

I currently have two guns rigged up as test platforms and continue to shoot them with much enjoyment:

14_inch_gun_II.gif


14_inch_gun_III.gif


18_inch_gun.gif


These are both finished with a matte grey heat cured polyester based powder coating. The coating is a little thick and made for a slightly tight gun assembly, but thus far has proved to be quite durable.

Take care...

those are sweet looking!! keep us all posted. even individaul e-mail on my part would be great!
 
Looking good...

I agree with other following this post on the request that you post the results of the T&E.

I like the looks of the last posted pick. What length barrel was used, 20"? Are the fold down non-optical sights G,G&G?
 
Looks like I am going to have to buy one when they are available for retail sales. My wife is gonna hate you BrobeeBiter!

This makes a semi-auto guy like me want an 870. The LCV is extremely high.
 
Hi Brobee,

I'm late in joining this bandwagon but I like what you are doing (is retail price quote in $CDN?) Whatever the cost, it's much more solid & practical looking than the Beretta M4.

I'd also like to suggest allowing for addition of white light/lasers to the top rail (I like all my controls in one place). Possible appliation for me in SD will be at night. I think that LEOs will be needing white light for their applications as well.

If it is too late or bothersome to add side rails onto the top rail, how about addition of mountable side rails?
 
Hi BrobeeBiter,

Good luck with the project.

My comment pertains to the fore end. May I strongly suggest that you re-look the issue of making one with the built in rail mounts. Maybe 3 rails, one on each side and one on the bottom, would be excessive. But how about 1 just on the bottom, or one on each side.

AFAIK no one is making anything like this for shotguns and someone SHOULD!

I believe you could do quite well just selling an item like this as an aftermarket accessory. The value I see in such a fore end is the fact that any M3 type light could be easily slippped on and off the fore end and used as needed. As you know many of us prefer some type of a white light capability on such a gun and don't want to spend the bucks for a Surefire front end light.

Regards,

Rob
 
Hello All!

nvrquit: The longer gun in the newest set of photographs is equipped with a 19 inch barrel and a two round remington magazine extension. The 14 inch gun is equipped with a Knight Armament RAS Flip up front sight (product #99051) and an ARMS #40 flip up rear sight. I mail ordered them from Sableco (http://www.sableco.net) and while they are expensive, they are in my opinion both very good products.

willyjixx: I am currently building an e-mail list of people to notify as soon as I take delivery of the first set of adapters. People on the list will be given the opportunity for first dibs. If you would like, send me an e-mail to [email protected] and I would be more than happy to add you to the list.

CWL: Thanks so much for your encouragement! I am still trying to quantify with more certainty the cost of doing business across international borders; my target price for adapters sold in the US is between $100 and $115 American dollars.

CWL & Rob62: I have long lusted for a surefire illuminated forend, and have almost bucked up the mega cash required for one more than once. Then one showed up at the local range I frequent and I had the opportunity to play with it for the afternoon. Was I ever dissapointed and glad I did not buy one! My dissatisfaction centered around it's huge girth and clammy soft plastic feel. I also felt the switching mechanism left alot to be desired. All that being said, I have to confess that the seemingly ga-zillion candlepower shaft of brilliant light that dissolves darkness on command is pretty seductive. It has had me thinking about the best way to incorporate an illuminator ever since. Currently, some of my thoughts are:

1. I really like the M3 illuminator type light. They are compact, very bright, and easily adaptable to the picatinny standard.

2. I recently acquired in a trade both a pump action and semi auto fabarm shotgun. (I'll post some pictures in the appropriate fabarm related discussion topics as soon as I can bring them home...they are at the range/shop right now pending my government to get their butts in gear with respect to the paperwork!) They both came with a longer forend with a short picatinny rail screwed upfront onto the bottom. I thought this was pretty cool until I fired them and found that even with the extended forend, the sharp edges of the rail made for some moderate punishment (with broken skin) on my support hand. I have not written the concept off though and I still have a lot more playing, er...make that research to do.

3. So with 1 and 2 in mind, I've been thinking that one solution is to manufacture a t-type picatinny to picatinny type fixture that would allow the M3 illuminator to be mounted sideways off the full length rail accessory to my stock adapter system. Esthetically though, I like the light inline (ie: underneith) the gun and am still toying with some other ideas for mounting to a forend.

As always, spirited feedback and discussion is highly encouraged and valued!

I agree with many of you that the Bad-A**-Cool factor of the gun is extremely high....I was out shooting slug and buck through both guns again this evening and had a big grin on my face the whole time....

Thanks again for your feedback....

Take care...

Would/Will the BATF....

... look upon the "non-fixed" stock and the "pistol type" grip in combination on a AR15/870 CQB equipped 870 as an evil assault weapon?

Seems each country has its own PC problems.
 
Brobeebiter,

I was thinking M3 lights as well. It is very compact, light, bright enough for SD/CQB environment and doesn't require expensive mounts.

I'd prefer a side mount because this keeps all controls in one area or side of weapon rather than one set for top and one set for bottom of SG.


You are going to make me 'soup up' my 870, a day I'd never think I'd see!
 
Hello Everyone!

nvrquit: I believe that the Assult Weapons Ban evil feature list applies to semi-automatic firearms and as such, we are good to go with the AR15-870 CQB Stock adapter for a pump gun. I readily admit that I am by no means an expert in this department, so people with more experience/knowledge than me please pipe up! I have written a letter to the ATF to clairify this and several other issues, and will keep you all up to date with their response.

Interest in the adapter is high enough that I am starting to have a considerable number of people asking to get put on a *RESERVED* list to save them an adapter for when the first manufacturing run of 150 arrives in late August/early September.

In response, I have created this "RESERVED" list of people who would like to secure their adapter. All you have to do to get on the list is send me an e-mail at [email protected] and I will both reply (to confirm receipt of your e-mail) and place on reserve an adapter for you. Those who have e-mailed me in the past are already on the list.

Once I have approved the quality control of the master mold/casting process and pay the remaining balance on the first production run, I will finalize and publish my pricing and begin to take payment from those wishing to purchase. This should take place in the next couple of weeks. People on the reserved list will get an e-mail with instructions on where to send the cheque/bank draft or how to use paypal. Once this e-mail goes out, your reserved status will be maintained for 3 weeks pending receipt of payment. If, after the three weeks is up and no payment has been received, an individual would be removed from the list and their reserved adapter would go back into the pool of those available for general sale.

I have 150 adapters on the way and a smaller batch of rear rail adapters and receiver length picatinny rails. Everything is still on schedule for late August/early September availability. The full length rail is quite expensive though (ie: at least 4 times the price of a receiver length rail) and I'm thinking that to more effectively manage my cash flow it will be made available by pre-paid special order (ie: manufactured only when I can afford to pay for it.


Does this sound reasonable? If not, discussion is encouraged!

Take care,

BrobeeBiter
 
the 1994 ban says:
SEMIAUTOMATIC ASSAULT WEAPONS and
LARGE CAPACITY AMMUNITION FEEDING
DEVICES under Title 18, UNITED STATES CODE, CHAPTER
44 as amended by Public Law 103-322 The Violent Crime Control
and Law Enforcement Act of 1994
(enacted September 13, 1994)
§ 921(a)(30) The term 'semiautomatic assault weapon'
means:

(D) a semiautomatic shotgun that has at least 2 of -
(i) a folding or telescoping stock;
(ii) a pistol grip that protrudes conspicuously beneath the action of
the weapon;
(iii) a fixed magazine capacity in excess of 5 rounds; and
(iv) an ability to accept a detachable magazine.

Paragraph (1) shall not apply to -

(B) any firearm that -
(i) is manually operated by bolt, pump, lever, or slide action;
 
Well, that would appear...

..., to have answered my inquiry as to the BATF/AW94 Ban applying. Though there is the never ending manner in which the BATF will sometimes "re-interpret" a ruling or section of existing code/law.

I guess it's best to wait for the "official BATF" response to BrobeeBiter's inquiry.

Excellent post though!
 
I would really love one of these for my Mossberg 590.
However I really don't have the need for the rail.

Regarding the top mounted safety of the Mossberg how about just a basic stock adaptor that mounted lower on the receiver? It seems to me that if the center line of the buffer tube was on axis with the magazine tube instead of the barrel you could still access the safety and use the original sights.

Recoil should still be better than a standard stock.
 
Hello All!

Here are the photographs of the illuminator mount I've been working on. I was holding off on taking the pictures as I am waiting for a more compact ARMS throw lever mount (the dual lever mount is a little large and a single would suffice), however delivery of this item to me has been delayed.

Universal_Front_Adapter_Gun.gif


The ARMS dual throw lever mount is what I am currently using for the bayonet/illuminator combination, and it is quite a sight to behold! One might think it's a little excessive though, and as such I hesitate to post photographs of the beast in her full glory (I would not want to frighten the children!).

[edited to add] I've been experimenting pretty heavily with the placement of the illuminator; it started out mounted way forwards and a little lower, however once I stumbled upon the ARMS throw lever mount and attached the whole nine yards to the rail, I quickly came to really appreciate the ergonomics of the M3 illuminator controls above the pumping mechanism. The support hand can easily access the controls and in my opinion/experience was extremely intuitive to use. All I can say about the light is WOW!

BluesBear: Pending commercial success of the 870 adapter, I might try my hand at an adapter for manufacturer's shotguns. I'd love to start the work right now, but in all realism it is more than likely not going to take place for some time. My sincere apologies...:(

Take care all...

BrobeeBiter
 
Wow! That's an impressive looking shotgun. You may want to consider reversing the light mount to put the light on t'other side. That way, it'll balance out the cant to port caused by the rounds in the Side Saddle.

How much does the whole shebang weigh? My guess, close to 10 lbs....
 
Admiral Dave: I hoisted the completely pimped up gun over the scale this morning and you are very right: she's 9.6 lbs with the side saddle loaded up. The light mount is ambidextrous...it can hang off of either the port or starboard bow of the battleship. I'm left handed and as such, my right is my forwards support hand. I've monkeyed around with the light hanging off both sides, and can't decide whether I like actuating it with my index finger (left side) or my thumb (right side).

All: As a side note, on one of the other forums I'm posting on, some recent discussion has been initiated on the M3 illuminator and how does not meet the muster with respect to military/heavy LE deployment. How about your experiences?

Take care,

BrobeeBiter
 
Can't help much about the M3. When Erick gets back, I'm sure he's much more current on this. I've heard through the grapevine there's much coming out of the Anti-Jihad about lights, infra red and so on. Stay tuned...

S'funny, my HD 870 with 18" barrel, extension and S/S runs close to 9.5. That's with 5 in the mag. I'da thought the setup was a bit heavier.

Meanwhile, let me know when you need Beta Testers....
