I was in your position in early 2010.There are lots of great choices for barrels.I settled on LW because of my experience with LaRue. Just finished 200 rds of practice ammo,Federal OTM.On good days,5 shot groups have been consistently in the .7 -.9 range @ 100. With more practice and better ammo I'm sure the groups will shrink. Good Luck with your build.

Happy with a Lothar Walther Match bull (6200 contour) in LW50 stainless.Choice of contour,chamber,twist,length,thread and crown type. Price was very reasonable... but be prepared for a wait. For myself it was 4 months. :(

You could use an Armalite AR10 catch. It has a longer threaded stud for better thread engagement.The catch portion itself is slightly taller.I have used this part on both CMMG and DPMS builds.Very happy with the results. It's about 12 bucks for the part. Works just fine with the Prince bullet button.
