4.5” barrels are chambered in .223 Wylde, made from 41V50, have 1:7 twist, and are .936” OD. Reliable and extremely loud. Use ammo comparable to M855 or M193 for best results, also runs great on Tulammo 55gr fmj, Tula gives the largest flash. Tends to run best with an H2 or H3 buffer, may vary with ammo. For AR pistols, SBRs, AOWs, and machine guns only, all NFA rules apply.
