When I get to it, it''l probably only be a BCM, BAD, or Noveske (assuming there aren't any quirks with mag compatibility for the gen IIIs). Definitely something nicer than a solid standard because it'll probably be the one I shoot most at that point.
Sic semper tyrannis.
Thus far I've followed the instructions in the sticky thread. Put the lower together, slap my BCM 14.5 Middy upper on it and shoot the snot out of it. If it works correctly over a case or two of ammo, I consider it OK for NFA conversion.
Could it be that someone mod'd the receiver to take old Colt FCG pins?
Have you tried a set of .17 pins?
I'd get some KNS pins and be done.
There are very few bad lowers out there. I SBR'd a Superior Arms that is a little too snug in the mag well to take Gen 1 PMags. I don't consider it the receivers fault, but Magpuls, and at least they got it right eventually.
I'd have no problem SBR'ing a non-gucci lower.
(That being said all my other SBR'd lowers are Noveske)![]()
Ive been looking for a good lower to SBR and a friend of mine sent me the CDNN deal on a POF Billet complete lower with POF trigger for 399.99. Purchased it and did the form 1 the same week. Waiting on it now............
I just pick the one that has the rollmark or selector options I like. Among my favs are:
1. Aero lower with NO PEW/PEW/PEW PEW PEW markings
2. Spikes pirate lower with PARLAY/PLUNDER/ARRR markings
3. Spikes lower with SBR prefix on SN
4. Zombie Defense lower with SAFE/FIRE/FRENZY
But that's the same reason I buy a lower in general. Like my JD Machine US Border Patrol lower (makes a nice build in FDE) and my Seekins lower (love the rollmark).
I SBR lowers that I want to pair with a barrel under 16 inches in length.
A couple of lowers that i like for SBRs: Mega Billet lower is very nice, so is the CMT billet stuff.
Last one i did was a Colt M4A1 Carbine lower but that was because of the gun i was building.
