5KU 14mm Negative Breacher Muzzle Break for Airsoft Rifles

"Very strong threads, i slipped up and shredded some of the receiving threads, no damage to the muzzle break threads, so pay more attention when installing than me.

"A super nice high quality muzzle break with an aggressive design. Only thing to be aware of if it comes with a grub screw that needs to be removed or else it will strip out your threads but overall 10/10 would highly recommend.

"Pros:
- Looks sweet
- comes with a grub screw
- threads we decent

Cons:
- I don't know what was up with the finish, but it was a bit neat up with nicks, rub spots or thin finish in places, etc. I just kept it because it's exactly what I wanted in my 8" M4. It's a shame it looks beat up before I beat it up myself, but it was $15 and not worth the trouble to exchange or return.
