I have a DB10ELB with the 18" fluted Stainless barrel. I have put a long range scope on it and really like the accuracy at 100+ yards, it ain't match grade with the crap ammo I use, but it's fun. I can at least ding a 12" steel plate with a 4" clapper center every time, and get a lot of double dings.
My problem is I want to mount a Magpul PRS stock on it, and found that the rail that the collapsible stock slides on protrudes into the attachment bolt hole preventing the stock from being attached when the stock is seated. The stock doesn't seat firmly against the tube lock collar, it has a gap about 1/16" .
Can I back the buffer tube out about 1/8" without incurring risk? Is the buffer tube MilSpec or commercial? It looks like others have had success, but without doing the above I can't see it working.
