Matrix 100% CNC 5 Bearing Hammer for WA / G&P / KJW / King Arms & Comp. M4 Airsoft GBB

"Installed in my G&P WOC M4 challenge kit with the other ambi steel parts available, fit perfectly.

"Used in a G&P WOC challenge kit with Inokatsu Superbolt (weight removed) and SHS trigger, sear and selector. Works great with 0 modification! Excellent piece, a little over priced, but that's what we have available here in Murica. Would not recommend adding this part with out everything else being steel also, which you can get here on Evike if you got the wallet for it!

"Works perfectly in my AGM GBB M4. Action is A LOT smoother and reduces wear on the bolt and the hammer with the small roller on the hammer. The bearings help a lot too. A must for the AGM GBB M4 or for a replacement/upgrade.

I haven't used this in a game yet since my rifle isn't combat ready yet, but the roller pin seems to be holding up just fine.

***This does not comes with the hammer spring***

Pros:
- Roller on hammer to reduce friction and wear on the hammer and bolt
- pivots on ball-bearings
- nice solid steel

Cons:
None
