That is some HOT shizznit there. Nice SBR.
Eric,
I have worked with RobArm and I am trying their trigger mod where they insert a set screw into the same hole that the grip screw is screwed into. This is something like our friend Bill does, but not to the same extent. It reduces the trigger travel, and takes out "most" of the two stage trigger. It has left me with more like a "Glock" trigger than a DAO Sig trigger. I am quite pleased with it and hopefully it should get better still.
I will find out more information on the mod. and post it if you like.
Before I traded off my XCR I switched to gas setting 3. I liked it more than gas setting two. The increase in recoil was barely there, but it made feeding and extraction better and more reliable with all types of ammoI took my new SBR XCR back out to the range again today to let my friend 1redgmc have a shoot. Well I will let him post his comments on my rifle, but again it work flawlessly with another 100 rounds down range. I was even thinking about dropping back the gas setting to #3 as the shells were being ejected a good 15 to 20 feet from the shooter.
I am continued to be impressed by this rifle and it's performance. I want another XCR in 7.62 NATO.
Thanks for looking, and thanks for the positive comments.
