PWS has the short stroke piston kit, which we use on our Addax GPU's we build as a dedicated AR piston using only brand new high quality components and barrels.
We also use this same short stroke system for performing a retrofit on customers uppers, and we can perform this retrofit on your BCM upper.
The retail cost for the system with installation is $425.00 plus shipping, but we also offer the members of AR15.com a Forum member discount. All you need to do is set up an account on our website, and email us your name and AR15.com user name, and we will update your account profile with the AR15.com Forum Member Discount.
The new long stroke piston system from PWS is used in our new ATAC-GPU (Advanced Tactical AR Carbine Gas Piston Uppers), we build in a few variations and calibers.
