Solid bcg with good specs, great machining, and assembly. The chrome key makes a lot of sense and I’m surprised more companies don’t produce a similar product.

Solid quality as usual from hodge and at a very fair price. Cheaper than DD, Colt and plenty others. Nice to see an upgraded chrome gas key as well.
