abooboo340 Posted December 11, 2013 Report Share Posted December 11, 2013 I have a DPMS.308 lower andwant to build a 6.5 creedmoor Since the DPMS uppers are impossible to find in 6.5cm, any thoughts on this for a barrel?: Bartlein AR10 Barrels S.S. 6.5mm 24". Will this work with most upper receivers? Any help greatly appreciated. Quote Link to comment Share on other sites More sharing options...
Dane Armory Posted December 11, 2013 Report Share Posted December 11, 2013 Lance was talking about making one of these. He even has a barrel blank. Hmmmm ... let me talk to him. Quote Link to comment Share on other sites More sharing options...
Tripledeuce Posted December 11, 2013 Report Share Posted December 11, 2013 Knowing less than nothing, I bought a DPMS bbl in 260 Rem. I told my wife to suprise me, and order everything else i needed. She ordered a Rock River complete, except for bbl. When the RR parts came, I had joined this board, and found that the parts were NOT supposed to go together! Well, I'v ben a custom smith for almost 50 years, and so I miked and measured, and checked headspace, and found I could, in fact, put a DPMS bbl on a RR upper. I had to open the gas port one size, and just "kissed" the chamber with a finish reamer,but other than that, I'v got almost 300 rounds through her with NO malfunctions, and groups are generally all less than an 1" at 100yds.

N Jensen Posted December 12, 2013 Report Share Posted December 12, 2013 I had White Oak Arms build my 6.5 creedmoor upper. Krieger barrel 26 inch, gas port moved fwd 2 inches. Shoots dang good. My only problem I had with it was all my mags that worked with my 308 upper would not feed ammo into my 6.5 C upper. Took awhile to find a fix for it. I've shot it out to 1,000 yds, no problems.

D.R.D. Posted March 10, 2014 Report Share Posted March 10, 2014 (edited) What was the fix? What mags wound up working? Also, why 6.5C vs 260 rem? Edited March 10, 2014 by D.R.D. Quote Link to comment Share on other sites More sharing options...
N Jensen Posted March 10, 2014 Report Share Posted March 10, 2014 I bought C-Product 10 round mags, but at first the mag wouldn't work. I ended up taking the mag apart. I bent the very bottom and very top (last coil) of spring at the same angle as the ones in between. The first and last coil were originally parallel with the follower and bottom of the mag, also the coil is only half the length of the other coils. I can't explain why it worked, but the 6.5 C rounds would feed fine. The ammo has to be loaded to 2.795 as well, ammo loaded at 2.700 don't feed, so hornday ammo 120g bullets won't work in my gun. Don't know why but I always hand load my ammo so it's no big deal. Quote Link to comment Share on other sites More sharing options...
EasyEJL Posted March 10, 2014 Report Share Posted March 10, 2014 the main thing is it says "Bartlein AR10 Barrels S.S. 6.5mm 24". so unless they meant its an LR308 and are using AR10 for commonality, you may have some headspace issues (or other issues) if you try and use it with a DPMS upper/bolt/etc. Quote Link to comment Share on other sites More sharing options...
D.R.D. Posted March 10, 2014 Report Share Posted March 10, 2014 Does that mean pmags are probably out of the question if its meant for AR10? Also, is it possible to headspace two barrels ( 308 & 6.5c) to use the same BCG? Im looking to use the same lower for 308 and 6.5c uppers. Would i need to change buffers if using slashes heavy buffer for the 308? Quote Link to comment Share on other sites More sharing options...

D.R.D. Posted March 10, 2014 Report Share Posted March 10, 2014 Sweet. thanks. I'm using an SI Defense lower, so it's DPMS pattern. Any idea which mags would work best for 6.5C? Seems they run pretty well with most anything when feeding .308. Sorry - didn't mean to hijack the thread ;-) Quote Link to comment Share on other sites More sharing options...
N Jensen Posted March 10, 2014 Report Share Posted March 10, 2014 The DPMS mags should work, I did have mine for a long time. I bent the springs, made them longer and probably wrecked them in doing so. When I bought the C-products, I made small change before going crazy on it. But the first try on the spring fixed it and gun feed like a champ after that. Maybe other people are doing fine who have a 6.5 C maybe they would say what they are using.

D.R.D. Posted March 10, 2014 Report Share Posted March 10, 2014 I hear this one works flawlessly with bolt action accuracy in 6.5C. I wonder what they use? http://www.jprifles.com/1.2.5_LRP07.php Quote Link to comment Share on other sites More sharing options...
