BigStew Posted April 2, 2020 Share Posted April 2, 2020 So been sitting with an old springer ruger min14 and a real steal folding stock for years now trying to figure out how to power a semi auto rifle. Anyway got given a nackard Glock AEP and having stripped it found the gear box fits horizontally into the upper receiver so was wondering if a MP7 gear box cylinder head is the same diameter as Glock gear box?
