Frequently Asked Questions

What are the key differences between the SOLGW M-76 and M-89 rifles?

The primary distinction lies in their handguard designs. The M-76 uses a rear tensioning screw and M-LOK at 3, 6, and 9 o'clock, while the M-89 features indexing pieces, additional barrel nut screws for stability, and more M-LOK slots at 3, 6, 9, 10, and 2 o'clock for enhanced accessory mounting.

What barrel specifications do the Sons of Liberty Gun Works M-76 and M-89 rifles feature?

Both rifles are equipped with barrels made from 4150 Chromoly Vanadium steel, featuring a 1:7 twist rate optimized for heavier bullets, a 0.75-inch gas block size, corrosion-resistant coating, and M4 feed ramps for reliable feeding.

How does ammunition choice affect accuracy with the SOLGW M-76 and M-89?

Ballistic testing shows that match-grade ammunition significantly improves accuracy. Loads like Federal Premium 77gr Sierra MatchKing and Frontier Cartridge 68gr BTHP Match yielded sub-MOA groups, whereas standard FMJ ammunition produced larger groups.

What quality control measures does Sons of Liberty Gun Works implement?

SOLGW ensures high quality by test-firing all their bolts and paying meticulous attention to detail, such as securely staking castle nuts in multiple places. They build to established AR-15/M16 platform specifications.
