98Z5V Posted July 16, 2011 Report Share Posted July 16, 2011 I'm curious about this as well. I used a DPMS LR308-specific lower parts kit on my gun, and I'm going to removed the mag catch and compare it do a brand new DPMS AR-15 mag catch. If anything is different, I'll post a pic - if it's the same part, I'll just come back in here and say it. Back in a few...Back - There is ZERO difference in the DPMS LR308-specific mag catch that comes in their LR308 LPK, and the DPMS AR-15 mag catch. Nothing different.

That is why you have to get the AR-10 mag catch Chad Quote Link to comment Share on other sites More sharing options...
98Z5V Posted July 16, 2011 Report Share Posted July 16, 2011 I only did the removal and comparison just to see if DPMS had a different catch for their .308 kit.They don't. Quote Link to comment Share on other sites More sharing options...
survivalshop Posted July 16, 2011 Report Share Posted July 16, 2011 My AR 10 catch was shipped yesterday ,so If no one else gets a photo comparison , I will , with measurements. Quote Link to comment Share on other sites More sharing options...

survivalshop Posted July 19, 2011 Report Share Posted July 19, 2011 Ok , some Photo's & measurements of the two mag catches .They are both the same as far as them being a rectangle .0296" long & 0.245" wide , the difference is thickness or depth of the pad that goes into the mag recess to hold it in . M16 pad --0.155"AR10 pad - 0.170"There is also ,on the leading edge of the M16 pad , a slightly beveled portion , but the AR10 is squared off & has no bevel .Must be to help the mag. be inserted. If you can't see it in the photo ,I can post a larger one .As you can see in the photo's the AR10 threaded rod for the button is longer ,AR10--1.092"M16---1.133"I also measured the thickness of the arms of the mag catch them self's & the difference is very small ,0.1015" for the AR10 & 0.103" for the M16 catch.I installed the AR10 catch & the Pmag does seem tighter & cycled some dummy rds. & it worked ,but actually firing the rifle, will tell if it works or not & I have laid out three brand new Pmags ,in the wrap er , to test. If its going to screw up ,it will do it on a brand new untested mag. Quote Link to comment Share on other sites More sharing options...
imschur Posted July 19, 2011 Report Share Posted July 19, 2011 Great, I look forward to the results Quote Link to comment Share on other sites More sharing options...
Triggs75 Posted July 19, 2011 Report Share Posted July 19, 2011 Nice review Survival. On your AR-10 latch, is the bolt angled in at all? Mine was slightly angled in to help keep the mag latch snug to the pmag. Chad Quote Link to comment Share on other sites More sharing options...
survivalshop Posted July 20, 2011 Report Share Posted July 20, 2011 Don't think its angled in any way . Have to take a closer look . Quote Link to comment Share on other sites More sharing options...
survivalshop Posted July 22, 2011 Report Share Posted July 22, 2011 AR 10 mag catch in my CMMG ,Failed !I have no doubt this catch will do better at holding a mag in , but the measurements I got , of cartridge height above lower receiver deck were the same as with the M16 mag catch in there .I tested all mags with one round in them to make sure they all held the bolt back last round & all worked.The same bolt over as with the other mag catch . Charge the first rd. & the second is caught in the feed ramp & mangled.Put in a DPMS mag with 19 rds. & I can dump the mag. . Put a Cproducts mag with 20 rds. , dump the mag., no problems .It was funny , when I got done dumping the second mag. I had an audience , where I was alone before . I think they wanted me to keep it up ,but testing as far as I was concerned was over .I can say if you have to have one of those bullet buttons , I would try the Armilite AR 10 mag. catch , because it is a lot tighter . I will probably put one in my DPMS 20" also. I have no problem using steel mags in my CMMG lowered AR 308 , just the way it is . Quote Link to comment Share on other sites More sharing options...
Triggs75 Posted July 22, 2011 Report Share Posted July 22, 2011 Thanks for the heads up. I will not get my upper until the end of the year, so I will not be able to test the failure to feed part until then.Chad Quote Link to comment Share on other sites More sharing options...
