View Full Version : BM59 tricompensator

11-21-2006, 10:28 AM
My understanding is a grenade launcher is considered a destructive device in CA and therefore not legal regardless of SB23 features. My question is re: the Beretta BM59 tricompensator. I have one I bought from Reese Surplus that will work on a Garand. I plan to put it on a Tanker I am building (no detachable mag so no SB23 problems re: flash-hiders). Question: how do I modify the grenade launcher part of the tri-comp to avoid problems? I was thinking about chucking it on a lathe and taking off the ridges that constitute the launcher and re-park. Thoughts? TIA.
