The SOLGW M4-76 is a great entry-level complete AR-15 rifle with all the features you want for a reliable, do-it-all carbine built for duty. This model features a 13.7” barrel machined from 4150 chrome moly vanadium steel, and QPQ Nitride finished inside and out. Attached to the end of the barrel is a pinned and welded NOX 3-prong flash hider to get the overall length to 16 inches. The six groove 1/7 twist rate is optimal for heavy 62 grain 5.56 NATO surplus ammunition. The Mid-length gas system and appropriate gas port size ensures reliable function under any conditions and minimal recoil. The government profile barrel and gas system are protected by the M4-76 free float handguard with M-LOK slots for full customization potential.
