Robocop1051 Posted April 12, 2013 Author Report Share Posted April 12, 2013 Magpul actually recommends the CAR10 with their UBR. Clint, from heavybuffers.com, advises that the Armalite AR10 buffer spring works best in combo with the CAR10. The problem with those "reviews" is that anyone can submit one. There is no basis for experience level. I would love to interview one of those reviewers to find out the real reason their rifle is FUBAR... I'm sure it's not user error! (Insert sarcasm here) If you can pull the charging handle and lock the bolt back, it is not a buffer issue. If you are still getting FTF, FTE or fail to lock after last round, there are other issues you may have to address. Really, all I read in most of those reviews is, "I spent $1k on a rifle and put a $100 part in it. Now I'm disappointed that it doesn't shoot like a $4k rifle." I especially hate the, "I have a X upper and a Y lower with a Z barrel and a random BCG. This new part doesn't fit in my freakish patchwork build, so it must suck. Why can't all companies make .308 parts MIL SPEC?" They should hold their heads under water till they figure it out. Quote Link to comment Share on other sites More sharing options...
phunk Posted April 12, 2013 Report Share Posted April 12, 2013 I agree and that is why I was ready to dismiss the review. I just figured I would ask just in case. Since posting, i have compared the UBR extension to the carbine extension on my ar15 and I cannot see any reason at all it wouldn't work. For christs sake it's just a tube. Proper inside diameter and proper length and we have a match. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted April 12, 2013 Report Share Posted April 12, 2013 It's listed with the product, right on MagPul's website. Their wording is as close as they legally get, in advising you to run Slash's buffer/spring combo with a .308 AR. If you go to their Industry Section, on another AR forum, they'll straight tell you openly about it. First pic below - hit their website, navigate to the UBR product page, and select the SPECS tab. Scroll down. Second pic - and the bottom of the SPECS info, you'll see this advice... Quote Link to comment Share on other sites More sharing options...
phunk Posted April 12, 2013 Report Share Posted April 12, 2013 (edited) Ya I already read all that before I purchased the UBR. Was only asking on account of one specific person saying that he personally tried it and it didn't work... I am not doubting you guys or Magpul or anyone. But I measured it myself and can clearly see that it's compatible, so we are in the clear. Edited April 12, 2013 by phunk Quote Link to comment Share on other sites More sharing options...
98Z5V Posted April 12, 2013 Report Share Posted April 12, 2013 That info I posted was also for other people, that search this topic out in the future - wasn't directly aimed at you, man. Cuts down on the confusion, in a back-to-the-future kinda way. <thumbsup> Quote Link to comment Share on other sites More sharing options...
cantshootafish Posted November 14, 2014 Report Share Posted November 14, 2014 (edited) So after reading this am I correct to say that I can use my mid-length gas 18" barrel with a magpul PRS stock containing a DPMS rifle length tube, spring and damper? I also plan on using the Gen II Syrac Ord adjustable gas block. Any problems with this combo? I am SO confused!!!! Thanks for all the help guys. I already had to make a custom length mag release button for the H&H lower but it turned out sweet.

survivalshop Posted November 14, 2014 Report Share Posted November 14, 2014 (edited) Barrel & its gas system has nothing to do with any stock configuration , throw an adjustable gas block in there & it can effect the actions performance , if not adjusted properly . Use the proper components for that particular stock configuration , meaning rifle length or Carbine & their proper configurations for the specific caliber . 308 stuff for a 308 & 5.56/.223 for 5.56/.223 .

blue109 Posted November 15, 2014 Report Share Posted November 15, 2014 honestly...get a normal gas block until you have some familiarity with the system. one less thing to troubleshoot. I personally have never had any desire to buy an adjustable gas block. get it running on dummy proof parts, then change stuff one piece at a time.

cantshootafish Posted November 15, 2014 Report Share Posted November 15, 2014 I've been using the Syrac Ord adjustable gas blocks for 4 builds now (besides other builds) on the AR platform and am quite used to them. The only .308 I did so far was a rifle length gas system with the A2 fixed stock, rifle length extension tube/buffer/spring and it fuctions perfectly. I just don't know the best way to approach the mid length gas system since I have had no experience with it in either platform and got a deal on a CMMG mid length gas barrel for the .308 build. I have the PRS stock and rifle length receiver extension in stock with the .308 rifle length buffer/spring. I have no problem with running the adjustable gas full open to zero in the system. So can anyone tell me if the rifle length damper/spring/tube will work properly with the mid length gas barrel.....or do I need a carbine length reciever extension, buffer and tube? Thats all I am trying to find out. Thanks. Quote Link to comment Share on other sites More sharing options...

kenichols29 Posted March 12, 2015 Report Share Posted March 12, 2015 I was curious i bought a buffer for an ar 308 and it doesn't have any weights in it like an ar15 buffer. Is that normal? Quote Link to comment Share on other sites More sharing options...
survivalshop Posted March 12, 2015 Report Share Posted March 12, 2015 (edited) What does it weigh ,,, Carbine or Rifle ? Edited March 12, 2015 by survivalshop Quote Link to comment Share on other sites More sharing options...
kenichols29 Posted March 12, 2015 Report Share Posted March 12, 2015 its a 3.8 oz carbine. Quote Link to comment Share on other sites More sharing options...
FaRKle! Posted March 13, 2015 Report Share Posted March 13, 2015 its a 3.8 oz carbine.That's the correct weight for DPMS' carbine .308 buffer. Not an optimal weight though... Quote Link to comment Share on other sites More sharing options...
BlazenT45 Posted April 8, 2015 Report Share Posted April 8, 2015 So does anyone have any experience with the JP silent captured spring and the magpul UBR receiver extension tube? Will that combo work or should I just use the CAR 10 And Armalite modified spring? Quote Link to comment Share on other sites More sharing options...
survivalshop Posted April 9, 2015 Report Share Posted April 9, 2015 (edited) There's a thread around here some where on the JP SC spring set up . Read what the owners & users have to say about it .
