Wgp 2-peice classic
Less weight making the guns recoil less like you didnt already know that though.
I had to sand down the front of the striker because it wouldent fit .
I got my striker used off the forums for about 40 due to some screw ups on my side of the deal so i just threw cash at the problem to make it go away. anyway thats all i got to say about this product and now im going to keep taling till i have used fifty words
Great for product but should be one of the last things you upgrade
