I am interested in picking up an Armalite AR-10A SuperSASS in the future. However, as others may agree, some of the furniture is less than agreeable. I personally want the lightest handguard on a monster like that as I can get away with while still being structurally sound. I see that some modification may need to be done to make room for the gas block, but I am still game. The first thing that came to mind was Troy, but does anyone else know of any very lightweight and slim handguards for AR-10's?

Thanks
 
If you are serious about a serious long range AR-10, I would pass on Armalite, or just about any factory rifle, except maybe Knights. You will have much more parts availability with DPMS-pattern rifle. The Armalite is 3100.00 with only 1 MOA accuracy,???? The rifle pictured cost around 2800.00, haven't sat down and added up everything, but that's close. Not included in that figure is the bipod, monopod, scope, and mount. Getting sub 1/2" groups with 175 GMM and not really broke in yet, only shot 40 rds. so far. Haven't even started reloading for it yet. If you would like a detailed parts list just PM me or I can post it here.

Nice looking gun otrman. Could you just post the parts on here cause I doubt I am the only one curious especially getting that small of groups not broken in or with reloads
 
Most of the parts I've looked at say they will fit both Armalite A models and DPMS, so I don't think that's a problem. I can find the Armalite for as low as $2500. And it sounds like that MEGA rifle is not too far off the Armalite in price, $2500 or so plus a $215 rail and $70 for a new stock (Not interested in the PRS). And what I've learned over the years is that people shoot much better groups than what a rifle is advertised to shoot. I'm also not an accuracy snob. 1 MOA with good loads sounds alright with me for a long range rifle that, at its maximum, would see 1000 yards.

armalite would be near the bottom of my list of ar10 style rifles for long range (or any range, for that matter)
 
I can assure you that very few parts will swap between the 2 platforms. The barrel nuts are different(and Rock River is different from those 2), bolt is different, barrel extension is different, uppers and lowers cannot be swapped between the 2. About the only parts that can be swapped between the 2 are the receiver extension, pistol grip, and trigger group. You will have a much greater selection of "match grade" parts with the DPMS-pattern than the Armalite. Also the 1 MOA from Armalite is not a gurantee. It sounds like you want to buy a factory built rifle and just make a couple changes to it. If that is the case look at the GAP-10 from GA Precision, base price is 2750.00 and you can set it up as you like when you order. Also if you don't have any experience with 2 stage triggers, try to find rifles at gun shop with them and see if you like the way it feels. I don't like them, to include Geissele, prefer single stage. One isn't better than the other just different. Here is the list:

Mega Arms Keymod receiver set-900.00
Timney skeletonized AR-10 trigger-275.00
KNS anti-rotation pins-30.00
Lilja 24" bull barrel-500.00
Precision armament break w/shim kit-150.00
CMMG LPK-68.00
Bravo Co. rifle buffer tube-20.00
Magpul PRS stock-245.00
Magpul MOE grip-20.00
JP Rifles BCG-485.00
JP Rifles captured buffer spring-133.00
YHM black gas tube-16.00
YHM gas block clamp-on-50.00

Rifle only total-2824.00
Rest of package:
Atlas bipod-280.00
Accu-shot monopod W/Tac-cap-105.00
Aadland Engineering Aadmount scope mount-280.00
IOR Valdada 6x24x50 35mm tube MP-8 reticule illuminated-1900.00

Total=5389.00

There are a couple places where you could save a few $, you don't need the entire LPK, just a few parts. Can go with different stock, but the adjustability of the PRS is awesome and is important when shooting from different positions. Do not go cheap on the barrel or BCG if you are looking for the most accuracy. Not to say other high end barrels are not as good, but the Lilja barrels are nothing short of amazing. I have 3 of them, one on similar build AR-15 consistently getting sub .3" groups, best is .254". One on a custom 10/22 build, all Volquartsen behind Lilja barrel. I haven't had time to really shoot it but buddy of mine that competes in small bore matches has borrowed it while his bolt action 22 is getting re-barreled. So far he has done 3 matches with it, 250-25x twice and 248 or 249-24x. And last on this build.
 
I think I may be mistaken in the parts compatibility. I just looked at the GA Precision and that raised receiver rail is not doin' it for me. I may put together a MEGA like yours, but with only a 20" barrel and not as extreme an optic as that. I just hope I can put one together and have it be reliable.

Great looking rifle,otrman.
However,I wouldn't state that you can't shoot good with a factory rifle. That might be true if you're shooting factory ammo,but shooting handloads,a shooter can make almost any rifle shoot good.
I bought a DPMS 260H for hog hunting,and this rifle has really surprised me with the accuracy it has.And,that's with it shooting 140 grain Sierra Gameking handloads.

The only mods done to this rifle are the buttstock,grip,and I installed a RRA NM 2 stage trigger. Optic is a Sightron SII 4-16x42 that I had in the safe,along with a Laser Genetics ND3 for night hunting.

This is a test load grouping at 100 yards-

That same load grouped 1.547" at 500 yards,so I'd say it's a pretty accurate factory rifle.My custom built 6.5 Creedmoor bolt action doesn't shoot too much better than this DPMS 260 Remington.
 
Txhillbilly-that is a fine shooting rifle that you have there. Not bashing factory rifles, its just a gamble as to what you may get. Most are average, some less so, and ones like yours. Kinda reminds me of something my grandfather used to say, "Even a broke clock is right twice a day". No one built the exact rifle I wanted, so I did.

.Scarecrow.-If you want to build I will be more than happy to help. Former US Army sniper and have built and help friends build many, many AR's both 15 and 10. Just PM me your email and I will give you mine and will help how ever I can.
 
otrman, I will keep that very much in consideration. I might as well tell you that my philosophy on this rifle will be as light as possible without sacrificing much accuracy or structural integrity, while being accurate. On that note, I am quite willing to have a rifle that is indeed, less accurate than yours. But if it's just as accurate, then awesome. The gun also has to be reliable, otherwise I'm not interested. I have always heard not to put together a "Frankengun" and fear that if I part everything out that I will get just that, a gun all with different parts that isn't reliable. I just found this today, it is DPMS Pattern and not too expensive for me.

In 94 I bought a KAC Stoner SR25 for $3K like an idiot I sold it so I could afford something else ... Kicked my self for years, bought an Armalite it didn't hold a candle to the Stoner, bought a DPMS ... same.

Finally gave up and started shopping for another Stoner; I found one about a year ago and got it for an unbelievable $2200. Using a Dillon 550 I rolled the load I shot in my first one and shot this group:

I'm sure there are other guns that will do better, but so far I haven't found another production gun that will. I'm currently trying to work up a load for my SiG 716 DMR but IIRC it's is .92" ... still 1/4" - 3/8" away from even being close to the Stoner on its best day.

The only other gun I have that will come close is a SiG SSG-3000
 
the old clinton gun ban era stoner sr25 match rifles are indeed amazingly accurate. reports are hit and miss on the newer generation.

mine is same as yours, but sent back and III put their quad rail on it. I added the PRS stock and magpul MIAD grip. also sold me the super cool old style KAC can.

i don't know about light handguards but you should email BCM and ask them if they plan to do their KMR rails in 308. they are amazingly light
 
I like BCM's new Keymod Rails, but I have to wonder, being they are so thin and have so much metal drilled out on the sides and bottom, are they structurally sound?

I've been wanting that can since I had my first one, however NFA items were banned by the state until 2007 ... Now I can have one but have always heard they have been out of production for over a decade ... Do you mind letting me know how much it was and if they have any more?
 
If you have the money and patience I would get a LaRue OBR. I have an Armalite AR-10 and it is a solid gun and if I were to replace the barrel with a match one it would likely be as accurate as you would want.
 
scarecrow, what you need to do is go to camp perry during CMP week. it's usually end of july, first of august. go to vendor row. you will find about 1500 precision rifle competitors gathered there, and about 30 vendors in huts with lots of goodies and usually very good prices. (like gun shows used to be)

camp perry is on lake erie in ohio, not far from you. fulton armory has been there every time I've been. (so are rock river, bushmaster, DPMS, etc) you can handle their stuff. talk to their employees and just generally educate yourself.
