It works fine now and doesn't jam. I had the stock weight recoil spring installed in that video which will not work with the added weight from the suppressor and 147grn ammo. I ordered a "tune" spring kit from wolff and found the right weight spring. It works 100% now. The ammo used is winchester 147grn TMJ so its subsonic The loud echo you hear is not the gun firing. Its from the 147grn projectile slamming into the wet mud at 1000FPS downrange. This video is old and I have more videos of better suppressors. Suppressor technology is advancing very fast these days as more and more find out how easy it is to legally own one. And yes, its a backyard, yes its legal and no its not a playground. Thats an unoccupied childs swingset in a backyard. Idiots....... Read me: To purchase Firearms or Suppressors email me: [email protected]
