frankly the spring and the hammer that I ordered are great the only problem is that it's a little long to wait because I'm from France otherwise it's reliable
Only replacement I can find for this price worked perfectly
To get it to fit on the Tokyo mauri akm probably have to cut a section off very irritating
You sent me the wrong part. You took weeks to respond. You made me pay to return it to an address you provided that was incorrect. You never refunded me. You stopped replying to me, and finally you ask me for a review. Well here it is - not good.
The Grub Screw is missing. So if you want that the Outer Barrel wont turn sideways just unstall a grub screw
