AK Recoil Buffer — AK-47 FRT Replacement Part
This is the AK recoil buffer that ships with the AK-47 FRT kit, available on its own. It cushions bolt carrier impact at the rear of the receiver, taking the edge off the shock your rear trunnion and internals absorb — which matters more once an FRT has you running higher round counts than the rifle was ever set up for.
What the Recoil Buffer Does
The buffer sits at the rear of the receiver and absorbs the impact of the bolt carrier at the end of its rearward travel. On a standard AK that impact goes straight into the rear trunnion. On a rifle running a forced reset trigger, it happens a lot more often.
The practical result is smoother cycling, less battering on the receiver internals, and a slightly softer impulse at the shoulder. It is the cheapest insurance you can put in an AK you intend to run hard.
When You Need One
- Replacing a worn buffer — buffers are a wear item and compress over time.
- Adding one to a second AK — buy the buffer without buying a second FRT kit.
- Running high volume — an FRT-equipped AK sees round counts that make trunnion protection worth having.
- Restoring a kit — the buffer went into a different rifle and never came back.

Installation
The buffer installs at the rear of the receiver with the recoil assembly out. No tools, no permanent modification, and it comes back out just as easily. Fitment is common to AK-pattern receivers, but check clearance with your specific dust cover and recoil assembly on first install.
