GAP10 Gen 1 BCG Parts

[c4xplsv]

Does anyone know what BCG parts kit is compatible with the GAP10 Gen 1 rifles? My firing pin retaining pin is bent and it appears to be the same diameter (albeit shorter) as the normal AR15 and the AR10 replacement I ordered is too large (thicker). These rifles were built on the hogan receivers at one point if that helps. Thx

Ah yes, vaguely remember that detail now that you mention it. thank you.

Do you have a sprung firing pin in your BCG?

If so, it’s an ArmaLite.

KAC is now using sprung firing pins in the newer SR-25s, and Savage uses them in the smaller frame MSR-10.

Yes it’s a sprung firing pin. The weird part is the retaining pin - it’s small diameter like an AR15 but AR10 length. But yes, ArmaLite rebuild kit matches what I have.
