This Geissele Super Charging Handle is designed specifically for the large frame AR platform. Geissele does not specify fitment for the PSA AR10 and I would recommend reaching out to the manufacturer for more information. This charging handle is known to NOT be compatible with the HK 762, Colt 901, DPMS Gen II, Adams Arms .308 Patrol Rifle, Daniel Defense DD5, and Sig Sauer 716.
This does fit the PSA PA10. It is an AR10 not an AR15 charging handle.
