I bought one from Mike too. I got a deal for a project gun plus spare parts so I got 2 barrels .177 & .22 or just basically just missing another stock. I had to replace the seal and spring that was installed with AG with the spare and had her shooting for a month and had to change the seal again and got that from crosman. Quest seal fits like a glove and was hoping the spring also..i Got it in but won't cock, too long. Re-installed the other spare spring and got her to shoot tight groups @ 17 yrds but was loud. I tried installing my Q-muzzle brake but no effect. It's all mechanical noise I guess from installing a stringer spring. She was shooting 600+ with 7.9 CPHP. I went through 2 scopes on this plinker and had to install open sight. I was able to lighten the trigger pull by polishing and honing and installing a lighter trigger spring, not too light or it will not cock right.
