Sons of Liberty Gun Works
Overview
The Sons of Liberty Gun Works Gas Block V2 is a solid .750" clamp-on gas block made from steel and finished with phosphate for durability. This component is designed to provide a secure fit on your barrel, ensuring reliable gas flow without the need for adjustments. It’s commonly found in carbine gas system builds utilizing the 5.56 NATO caliber, making it a practical choice for standard AR-15 configurations.
Sons of Liberty Gun Works Gas Block V2 - .750" was the fourth most added gas block on GunPartPicker in August 2026, behind the Bravo Company AR-15/M16 .750 Low-Profile Gas Block, with about 6% of all gas blocks added to builds. Down from #3 in July. Builds with this gas block are nearly all chambered in 5.56 NATO, mostly on mid-length gas (89%, then carbine-length 11%), and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today 5 of the 7 retailers we track have it in stock. The best price crept up from $41.99 to $45 over August 2026. Buying today, the lowest price is $45 at Brownells, above August's low of $41.99, so a better deal may come back.

Sons of Liberty Gun Works V2 gas block in .750 is a buy again product. Steel construction with even phosphate finish. Set screws thread cleanly. Aligns with the gas tube without any fitting. Solid budget gas block from a quality maker.
Sons of Liberty Gun Works V2 gas block in .750 is well machined steel. Set screws thread cleanly into the body. Wish the package included spare set screws since they can strip with overtightening. Otherwise solid block.
