Compatible with the SP9A1 and SP9A3 gen2 guns only
Older A1 guns have two rods that run between the bolt and buffer block
The older two-rod guns are not compatible with this buffer block
This buffer block is designed to be used in conjunction with the stock factory buffer block (see product pictures)
After removing the recoil assembly, simply remove the retainer that holds the coil spring, slide this buffer block over the spring, then compress the spring and replace the retainer
All set!
It is recommended to have professional installation on all parts.
Don’t forget to lube your guns and moving parts correctly!
