Geissele Super 42 with H2 buffer in black is a quality complete buffer tube assembly. The adjustment lever was stiff initially for the first week of use before loosening up. Now slides positively. Solid recoil reduction.
Geissele Super 42 with H2 buffer in black has noticeably less spring twang than a standard music wire spring. Cheek weld on the tube is fine, no roughness. Black anodize matches non-DDC builds.
