For the longest time I wanted to do up a nice AR build. But I procrastinated about it for literally years and got caught off guard by all the changes to US export laws. So for the past two months, I've started working on finding and ordering all the stuff I want for this rifle. Interestingly enough, the only things I havent been able to find in Canada are the optic mounts. Pretty much everything else is either already here or on order/shipping.
The base rifle I'm starting with is on order:
- Sabre Defence 16" Mid-Length Gas 5.56 Flat Top
So I'm changing to/adding the folowing:
- Troy front and rear flip up sights
- LaRue 12" free float railed handguard
- LaRue low-profile gas block
- Magpul XT panels on bottom and sides, ladders on top
- Smith Vortex flash suppressor
- Magpul MIAD
- PMAGS (of course)
- BFG single point sling and a Vickers two point
- Trijicon ACOG TA31F in a LaRue (also because I couldnt decide, Aimpoint CompM4 in a LaRue with a 3x magnifier in the LaRue rotating mount)
- Tango Down vertical grip (might switch this for a KAC or a LaRue FUG)
- I've got a green laser thats going into a LaRue offset mount
- As for the stock, right now I've got a milspec CTR and a Troy OEM M4 reciever end plate with push sling mounts. Although I'd change this in the unlikely event I manage to locate an M93, UBR, or SOPMOD
So here's what I'm wondering:
- I'm not expecting sub moa accuracy. I wanted something that would be reliable and eat almost any ammunition I feed it. It should be effective with 55gr all the way up to 75gr, should it not? Would a .223 Wlyde in a 1 in 8 twist with polygonal rifling be better?
- I'm unclear on the barrel profile designations. Government, Medium, HBAR, etc. As far as I can tell, the base rifle would have a medium profile/contour(?) where it tapers to a narrow diameter under the handguards and then increases in diameter to 3/4" at the FSB and stays close to that up to the muzzle. Given that I'm free floating it, wouldn't I want a barrel that tapers to 3/4" and remains relatively consistent? (think along the lines of the noveske N4 barrels) If anything I'm thinking it might look better. What kind of barrel profile would that be? Mr Wolverine, is that kind of change available?
- I can't decide which I'd rather do; the TA31F or the Comp M4 with the 3x magnifier on the fancypants rotating mount. At this point I'm kinda thinking both, and just use whatever I feel like that day.
- I havent even thought about what would be a good flashlight setup
- Are there any strong opinions on the vertical grip? Ive got a Tango Down Mk46, and there's a LaRue FUG (supposedly) on the way. I dont mind the way the KAC one looks but I'd imagine its as hard to find as the LaRue and there probably wouldn't be any advantage over the other two.
Before you post "Why wouldn't you just do it on a Stag?", I hear nothing but good things about AEI but Stag doesnt make a middy 16".
Thoughts? Opinions? Experience? Similar Project? Trolls/Flames?
