PegLeg... my SBR is built on a real LMT MK18 upper with the KAC furniture ...in addition to the $200 tax stamp, I paid $200 for the trust and $35 for the engraving... my "pistols" use a KAK 8 1/2" buffer tube and rubber furniture tip, not a blade or brace, so to be not at the whim of the ATF
update on the Charger... it points exceptionally well with just a slight modification of a rifle hold with it extended, I
probably won't bother with pursuing the AFG... the Vortex Spitfire really works well with the pistol extended, much better than I expected... at 25yd, you just throw it up to eye level, and pull the trigger
