VLTOR A5 H1 buffer at 4.56 oz works perfectly with the A5 receiver extension on my 14.5 mid. Smoother recoil impulse than a standard H1 in carbine geometry. Inside weights dont rattle. Fits any A5 spec extension.
Switched from a standard H1 to the VLTOR A5 setup on my 14.5 mid build. The longer A5 buffer with the right spring smooths out the recoil impulse. Cycling is more consistent suppressed too. Weight is correct at 4.56 oz, matched a scale. Worth swapping if you have A5 receiver extension.
