If your prepping for SHTF senerio you better make sure it will run steel ammo also , you want it to shoot what ever may be available. I have a couple of 1:7 barrels and they really like 62 gr , its far more accurate than the 55 in my gun with that barrel twist , 1:9 seems pretty universal and can basically shoot what ever you put to it from 45g to 75 gr without issues . Depending on what your willing to spend , I will suggest some good brands with good reps . BCM, LMT, Stag, PSA, RRA, S&W MP15, Noveske, Colt, Windham Weaponry, Mid range and higher DPMS, and the older Bushmasters made in Windham ME
