Great fit and is definitely less impact on receiver very noticeable when running suppressed. As always great service.
The unit’s construction is well designed. Installation was very easy. If you could make a retaining ring out of metal and include it with the unit, it would be the ultimate replacement available.
Got to the range today.... So my goal was testing the new prototype shock buffer and also installed the extra power recoil spring. Installation was easy. I ran 50rds of 115gr, 50rds of 124gr & 50rds of 147gr. The gun ran flawless, no malfunctions of any kind. Recoil was even less than before (very smooth). A nice improvement.
Ordered this as a prototype the day I got the email the construstiin and finish were fantastic felt recoil was improved feels alot better than the steel on steel after a few range days and over 3500 rounds later after cleaning I inspected the buffer and it is still in great condition no cracks chips or deformations must have for the PC carbine. Mcarbo always makes top notch products that will keep me coming back!
Works like a champ.
