Barrett's of Caterham are official suppliers and repairers!
Is your PFS noisy when compressed then it probably needs servicing.
Most people fit them then just leave them alone, but with the compression happening every time you shoot, the compression washers wear, get dirty and go out of line.
Service will include:
Strip and clean
Remove compression washers and clean
Realign washers and rebuild
We can replace missing screws on the cheek piece at an extra cost
Your stock will be returned with exactly the same dimensions, you will find the recoil will be smoother and slightly softer.
Any parts or repairs will be quoted:
