Who is going to jump in first to test this out? I recently committed to the Trident setup, so I'm out of this one

Scuttlebutt is that Satern is making them. http://68forums.com/forums/showthread.p ... 0BM-barrel

I'm happy with my Trident, so I guess we'll have to wait to see.

Satern makes a very good barrel. I've had a 6.5 and a 308 from them, both shot sub moa with most loads.

Don't toss me under the buss for this just yet :o but I also have a 45 Raptor barrel on the bench waiting on a SLR rail. Plan is to run it side x side with my 16" 450B and see what shakes out.

actually just tested it for function yesterday and it ran ok with a minimum book load of Lilgun and a 240gr xtp mag. Just need to scope it and get some bench time in now.

Is it a Liberty barrel? Or is someone else making them now?

I believe Satern is the only maker, they have them in their barrels for sale section from time to time.

I bought one and I am just waiting on a magazine and a BEV block to show up, maybe tomorrow, to put it all together. I went with a 15" rail and the gas block was too tight, I machines .020 off each side towards the top but it looks like I need to take another .010 off of it. I'll post back once its all together.
