    • Not a silencer but sends most of the sound out front of the gun.
This is solid. Works well, looks great on my sub-2000. I recommend this.

    • Excellent
I put one of these on a 223 while waiting on the suppressor, much more pleasant to shoot than with a side blast muzzle break, still need hearing protection, but not nearly as bad.

    • don’t recommend
doesn’t work, yes it threads on and everything but i shot my umarex fn 502 with it on and now my 22 doesn’t work, i think it broke the firing system, also tried on my glock 17 gen 5 and it didn’t have enough pressure to rack another bullet i had to discharge the shell manually, so overall don’t think it’s the best bang for your buck, wouldn’t recommend, just save your money and buy a better one not on amazon. ... show more

    • Good buy for any 22lr
Works good for 22lr and smaller. Anything hotter than 22lr the end will fly off. As a linear comp it works well especially on my 22lr pistols.
