Anyone know if possible to convert model 51 2 & 3/4 in to 3 in? Barrel only.
The 3 in barrel only has one gas port in barrel vs 2 in the 2 & 3 in

I don't see how .
theres more then just ports at play...
chamber length as well as part of the barrel that fits into the receiver.
a receiver that's 1/4" longer in 3"

I don't know for sure but looking at the differences and people in the know' comments. It looks to be cost prohibitive considering the price of machining both the barrel and receiver.

I have made the swap. On each.

Worked fine for me. No need for a conversion, just put the barrel on you are wanting and shoot it.

Return to Model 51
