I may need to build another precision upper one day and if I do, I’ll probably use a Shilen barrel. My cousin has a few of these and they’ve all shot well.
Right now he’s using McGowan and he’s been pleased with all but one of those. I put together an upper for a friend of mine with one and it’s very accurate. I think that’s 4 or 5 McGowan barrels that all shot well except one and it had a chamber problem I think.
Lots of decent barrels out there but I don’t hear too much about these two on here.
