RA-Tech CNC Steel Bolt Carrier for WE SCAR-L Airsoft GBB Rifles

"As soon as the rear screw hole in my stock bolt broke, I had just to buy this. Since this is made out steel rather than some weak alloy metal, it should last for rest of the life my we scar l. Also, there's diffinitely a stronger recoil with slight slower rpm (closer to the real steel rpm), due to the heavier weight. I highly recommend this for longevity and recoil.

"Great part. A recommended upgrade for longevity. Over time the screws holding the upper nozzle guide may come loose, in some cases the threads can break on the stock alloy bolt causing all sorts of issues.

"Literally just installed this thing 4 or 5 minutes ago...This thing is amazing. Only and i mean ONLY problem is that the top nozzle guide required a half millimeter of filing to fit to the bolt. Other than that this thing is awesome. The recoil is noticeably different. Im currently using black nurpol gas and a noveske flash hider with my scar. Between the flash-hider as well as overpowered gas AND a steel bolt carrier my scar puts the fear of god onto the field, the thing sounds like a cannon. Again only downside is the little bit of filing but other than that id say go buy a noveske flash-hider and go blow out the eardrums of your teammates .
