The Bullpup, she is finished, finally. I think. Almost

Pretty cool! Neat nomenclature, too. :D

I am curious, though...why the ATN on the left side? Being mostly righthanded, I put a OKO on the right side of my three-gun upper...after trying it all over both sides of the handguard at various angles using the ultimate tactical non-permantent scout-rail attaching devices (hose clamps). All six or seven of us "serious" 3-gun ubergeeks around these parts settled on various angles of the 1-3 o'clock mounting rail...

I can only assume then that Futo is a southpaw. Correct?

I get it. CQB/close-in type shots, quickly rotate the rifle 90 degrees clockwise (from shooters POV), butt is horizontal on your shoulder, and you've got a "homeboy hold" but still have a sighting system. The rifle is ejecting straight down then.

A right hander would put the reflex on the right forward rail, and rotate 90 degrees counter-clockwise instead, but would suffer upward ejecting brass, at least with a bullpup.
 
Andrew and Wakal, that's right, homeboy hold, and I actually started off by asking Kurt to put the rail on the RIGHT side, but he put it on the left instead, to keep brass from hitting me in the face when the rifle is turned - more important with the bullpup config. (read my post above in detail on this). So I deferred to Kurt on that, but no, I am right-handed, not left. I actually thought it would be unweildy for me, a right-hander, to turn the rifle 180 to the right (with the left rail), but it's actually quite easy to do WITH the front pistol grip (and rear pistol grip) as a good, quick torqueing device, and as noted, brass goes down, not up.

Look at this doohickey at Brownell's - if I turn it 180 degrees from it's anticipated mounting, such that the red dot is in the 10:30 to 11:00 o'clock position, it will probably work nicely, and frees up the left for the flashlight, so I can put my grip further forward, and still keeps the brass outta ma face. Actually, if I get this one, then I can try it both ways (red dot at 11:00 and 1:00), and see if I get hit with brass at 1:00, and change it to 11:00 if I do:

Onslaught, that may in fact be my rifle, but Kurt emailed me today saying that he didn't charge me for the front sight, and therefore didn't send it - but he may have had it on mine for that pic - I dunno - so yes, I'm going to order the fold-down front from Bushmaster today! Coolness - hope it's the right height for use with that Ashley Outdoors peep - I think it should work given the adjustment ability of the A2 style screw-in post.

No, I didn't notice any weight reduction from the lightening slots, because obviously the overall weight is much heavier, given the 4 new rails on it, one of which is very long. It's a little heavier than ideal, true - I *may* at some point take the left P rail off as unnecessary. I don't think I'd shorten the barrel or you lose the main advantage of the bullpup - a long barrel, giving you high velocities in a still fairly short overall length - doesn't make sense to me to shorten the barrel any, algthough Kurt will certainly do that. His prices are good (though it DOES add up), and he does a good job, but expect a wait - he took a long time getting it done - I guess he's swamped down there - both literally and figuratively.

Actually, the scope HAS TO go on top, not off to the side, or your long-range ballistics get SNAFU'ed. I like the idea of a little red dot at 11:00 - I'll post some updates after I re-configure - doh - no rest for the wicked, I tells ya.

PS. Onslaught, you said:

"Personally, I'd raise the scope and leave the rear ghost ring mounted all the time... In fact, if you attached that scope, rings and all, to either an ARMS #5 or the Rock River Arms (improved) equivalent, you could probably use the peep sight UNDER the scope, and do away with that ATN sight for close work... "

You may be onto something there, and I had thought about that, but dismissed it, with the idea that I want that scope as low as possible. But, there are several "pros" to doing that....First, it elimates the weight, reliance on batteries, and necessity of turning the rifle to shoot. Second, if the scope is for longer work only, then there's not necessarily a NEED to get the scope as low as possible. I may do this IF the front sight can be adjusted to line up where I need it for close work. This appeals to me, particulary to eliminate reliance on batteries.

"WHICH, by the way, considering the Trij. sight uses the Bindon Aiming Concept, you really have no need for the ATN sight, even as it is now. Your scope does both."

Well, hmmm, not exactly, I don't think. First off, I'm not sure of the EXACT definition of what does or does not constitue a "BAC" reticle. This one on the Accupoint is illuminted, yes, but it's a very precise point/triangle on the non-illuminated post. So it is (a) not the quickest acquisition because it's not very large - certainly not like the donuts on some ACOG - I think some ACOGs have donuts or large triangles, don't they, or am I thinking of the Trijicon reflex? - and (b) the Accupoint still has the "problem" of shooting a fair amount low at fairly close ranges, which will be exacerbated by a ARMS or other see-through mount. Thats FINE, as long as I have a quick and dirty yet still dead-on sight, and a red dot is great for that. Irons can be good too. I'll have to just order the irons, practice with them, see where they're hitting, with adjustment, and how quick they are. If they're very quick, then I'll probably just go with the ARMS mount and forget about the red dot. If they're not so quick, I'll 11:00 oclock mount that red dot, keep the scope low, and have the flip up/stoway irons for backup only (for when scope and red dot both go TU).

Jeez, for that kind of money I'd expect all that plastic junk to be pulled off and replaced with metal or walnut! Just don't leave it in the trunk of your car on a hot day...

BAC is a "concept" rather than specific hardware, but since I have never looked through the Accupoint, I can't say if would work or not. Going from the pic I saw on the SWFA site, the triangle looked larger than you describe, so I was going on what I saw.

Any illuminated optic that you can look through with both eyes open and see JUST the reticle superimposed over the non-magnified picture that your weak eye is seeing is using the "Bindon Aiming Concept".
As for the POA, POI... If your reticle were larger as it appeared to be from the pic, then it would work similarly to the "ACOG Reflex" 12.5 moa triangle where you use the tip of the triangle for 50 yards +, and the triangle as a whole for <50 yards. The POA is 3" lower at 50 yards this way, and if the Reflex II were a better optic, I'd still be using one.

I'd definitely practice with it and see how well I could see the reticle with both eyes open and moving around. I would imagine that red worked better than amber, and judging from the square around your light gathering piece, yours is the latter.

The Bushmaster front sight should be just fine, given what Kurt had to say in this thread specifically on M17s sight ideas.

Keep us posted, as I'd like to see how she continues to transition.

it wouldn't be too hard to make that thing eject leftways.


cut another ejection port, install a left hand ar-15 bolt.
That's what I figured too. But apparently, the internal workings of the Bullpup are a lot different than the AR. There's a "bolt guide rail" on the left side of the receiver that would block left side ejection. The entire rail would have to be moved to the right side...
 
Onslaught, you are right - Kurt told me today that the Bushy fold-down front sight will work perfectly with the Ashley Outdoors rear - and he tested it to be sure even. So I ordered one - I'll keep yas posted. I'm pumped.

The triangle point on the Accupoint is quite small; smaller than it appears in that picture. But if BAC means you can keep both eyes open and just see the reticle imposed on the target, then the accupoint does that - particularly at 1.25-2x. But the POA and POI is gonna be a tad off at very short ranges, regardless of the reticle size, of course, with any zero, but particularly with a relative long zero such as 200 - but this zero makes sense for this scope given it's precise small tip, you see.
 
I keep coming back to this post, just so I can download your pics again :D
I could take that same $1800 and all your "accessories" and blow it all on my pre-ban Bushmaster AR15, and yours would still stand out... MAN I want one!

I also figured out which fictional character would be most deserving of a rifle like yours.... Sci Fi's most tactical of all...

Here's an explanation of the Bindon Aiming Concept because I'm still not explaining it exactly.

I have never really looked at the Accupoint as an option, but thanks to you, I am now. Like I needed to spend another $600 on my rifle! Just don't tell my wife!

One thing to consider on that POA stuff. With the AR, depending on where you zero, your bullet crosses POA at, lets use 50 yards, then again about 200 yards, with about a 2"+ variation above or below the rest of the time out to 250 or so. Now I've never shot 3-gun, but I can't imagine a scenario where you'd need a shot to be more accurate than 2" from POA in a competition. Of course, your rifle will probably vary since height over bore is probably different, but the concept should be the same... A little extra playing around and you could figure out exactly where your bullet is at those distances.

Good luck, and if I haven't said it enough yet... Nice Rifle! Keep us posted!
 
Update

Onslaught - Boba Fett - lol - yep this is some stone-cold bad@zz tactical shiz that would make even Boba proud to shoot. :)

Okay, here is Mary Ann after some additions/changes since prior pics:

-Out with the Weaver rings, in with Leupold high see-throughs. I really hadn't planned on using see throughs, in order to get the lowest mount possible, but after tinkering with it (it was indeed TOO low), by the time I got the scope as high as I liked, there was room to use a see-through so why not?
-Bushmaster fold-down front sight.
-Sling
-Out with red dot; flashlight moved to left side
-B-square bipod, "Roto-tilt" model, on Bushmaster's weaver bipod adapter (swivel stud)
-Cheapie "flip-off" rubber scope covers (they stay on the scope tube).

Onslaught, as far as the PBR thing goes - here's my theory on that... Yes, you're correct that in theory, a 5"-target-based PBR is fine, and that's what you'd get with this setup at all ranges to about 225 with a 200 zero (because of the -2.5" at very short ranges, even though you'd only be 1.5" low at 225 or so, not -2.5 there). BUT, that assumes a perfect hold, which is not likely standing, under pressure, on the run, etc. So, to allow for such sighting/holding errors, I run with a THREE inch-based PBR, which gives me about a 5" target coverage in practice, taking into account errors in holding. For example, if your target is 5", and you're 2.5" with a perfect hold, then the slightest error in hold results in a miss. Since 5" is in fact a good practical range, I tighten up the ballistics numbers to a 3" based PBR to cover such errors. A 60/62 gr .223 bullet with a muzzle vel or 3,000 fps, with a 189 yard zero, is only -1.5" out to 217 yards. But -2.5 at 5 yards. Hence the idea of using a red dot for say, 5 to 30 yards, and still use "dead-on, no-think" sighting. Now, however, having said all of that, I've decided to forget about it, and just simply train to hold a tad high at short ranges (not too hard), and rely exclusively on my primary sighting system - the Trijicon scope (with irons as emergency only). Especially since with all the other junk on it, it's already the heaviest "light rifle" I've ever felt.

Dunno because I don't have an accurate scale. But my 20+ year old bathroom scale of questionable accuracy seems to indicate about 11.5 - 12.0 pounds, with everything except mag/ammo. What's a good but inexpensive accurate scale to measure gun weights anyhow?
 
That's one hell of a tactical ironing board. Are those tactical undies I see in one of those pics? :D

That's an amazing rifle, Futo. Good job.
