UTG Pro 6-pos lever stiff
Reviewed on April 21, 2026Verified with Build

Leapers UTG Pro mil-spec 6-position buffer tube has the standard QD socket. The release lever was stiff initially - took some adjustment cycles to break in. Now slides positively. Threads to a standard castle nut. Functional budget option.
