I sent
@unclemoak a Craddock 6.5cm barrel where they used a Bartlein gain twist blank to convert for my 15.5" mws upper. The barrel is 22" long and has a +3 gas system. It's one of the signature series that they usually keep in stock. As usual his work was fantastic and the turn around time (even being that he wasn't officially doing MWS conversions yet) was totally on par with his normal MRP conversions.
Took it out last weekend and just threw together some factory Hornady 140 ELD clone loads at 41.5gr of h4350 seated to mag length using some brass i found at the range in recent years and cleaned up as best as i could. It shot everything under 3/4" and most groups were 1/2". Had a few .3 groups if not for that measly 5th round flier. I also did some extras working up to 42.2gr just to see how we were looking on pressures and velocities. It handled the 42.2gr load no problem and velocity was 2720fps. Gonna work on some more load development and see what it can do with some good brass from the same lot. Either way I'm totally satisfied with the work he did and the way it shoots so far.
I switched to a heavy buffers 10oz buffer just to see if it would run and sure enough it did. With the 10oz buffer and the +3 gas this thing recoils so nicely. It felt like shooting a 223. The factory 6.5 barrel and standard rifle buffer was annoying to shoot. Very violent recoil impulse. I forgot to bring my rod so I didn't get a chance to shoot it with my TBAC 6.5 ultra 7. Hopefully next time.
Anyway here's some pics.
