The receiver stubs are gone with a little dremel work, but how do you remove the old rivets still stuck in the trunnions?

 

[cruzie27]

once the barrel is out,...

you can drill them with a smaller sized drill,..and beat them out with a pin punch and hammer,..

or

useing a smaller drill,..drill it,. the go up in drill size untill the rivit spins,.. and then knock/tap them out.

either way,.. a set of punches and a hammer is needed.

Ditto with what Cruzie27 advises and when you are drilling, drill slooow and use alot of oil. If you try to rush it, you'll break your bit for sure. The keyword is slow.

Good luck.
