From Sons of Liberty Gun Works comes a gas block that’s produced from tough, durable and long-lasting 4140 steel with a journal size of .750. The journal size is important to note as this gas block is designed to work with any handguard on the market.
This low-profile Gas Block V2 is produced with knurled set screws designed to work best with properly dimpled barrel and will provide a lifetime of valued service when installed correctly.

Great gas block. Works as expected and simple install.

It works! Fits great on the BA 300bo barrel I bought. Be aware there are no dimples, so get a dimpling tool somewhere as well. I used an SLR one.

Very high quality gas block. Install was easy on a dimpled barrel. I like that the front of the gas tube journal is open, makes removing a worn out tube easy with a punch. Can’t go wrong with SOLGW!

The most beautifully machined and finished gas block I own, genuinely excited to install this due to its exquisite craftsmanship. The SOLGW text engraved on the side is the cake icing.

Nice tight fit on my SOLGW 13.7 barrel. The knurled set screws are a nice addition.
