LeatherNuts Posted April 3, 2015 Report Share Posted April 3, 2015 (edited) And the bolt not going into full battery is one. Went to the range today and out of 100 rounds i had to rerack 90 of them. Headspace checked, dripping in lube, no visual issues. The only thing I'm noticing is that the bottom face of all the rounds have one hell of a wear mark from the extractor. Almost like its not opening enough to grab the lip of the shell, but just slamming into the bottom of it. Any thoughts before i find a professional?

FaRKle! Posted April 3, 2015 Report Share Posted April 3, 2015 Does this occur if there's only one or two rounds in the mag? What kind of extractor setup do you have? Can you open the extractor by hand (should be able to, but it shouldn't be super easy). Quote Link to comment Share on other sites More sharing options...
Dane Armory Posted April 3, 2015 Report Share Posted April 3, 2015 Pull the BCG out and take two pictures , front and side. Are the extractor marks , deep ? Did you use more than one magazine ? A.] MagPul. Plastic B.] DPMS. Metal--- are there lines on the brass? Quote Link to comment Share on other sites More sharing options...
washguy Posted April 3, 2015 Report Share Posted April 3, 2015 (edited) Leather when you assembled it...did you take and point the muzzle down and drop in the bcg? it should almost go into battery ... making sure the gas tube is aligned properly so its not interfering with the gas key itself.Did you take the bcg apart and service it before using? did you put one cartridge in a mag...fire it and did it lock back? :) Wash Edited April 3, 2015 by washguy Quote Link to comment Share on other sites More sharing options...
LeatherNuts Posted April 3, 2015 Author Report Share Posted April 3, 2015 (edited) @Farkle - Happens regardless of number of rounds in the mag. Ares NiB bolt and carrier with stock extractor and spring. Extractor broke my plastic cleaning brush attempting to get it to move. It is ridiculously stiff. @Dane - There is actually material missing from the lip of the shells. Magpul mags, one 20 and one 10. Pictures to follow. Normal scuff marks on the brass. @Wash - Bolt gravity drops into battery very well, misses complete lock by maybe a 32nd of an inch. Gas tube isn't interfering. BCG was serviced prior, bolt locks to the rear on last round without fail. As an update: I'm cleaning and I'm finding a lot of brass shavings the same relative size as the face of the extractor and when i pulled the bolt apart there were a lot of shavings under the extractor in the firing pin track. The extractor also has the rubber donut on the spring, is that normal for the 308 platform? I'm aware of why it was done for the M4,but not sure this weapon would have the same issues. In case I miss it later, thank you all for the support. Edited April 3, 2015 by LeatherNuts Quote Link to comment Share on other sites More sharing options...
washguy Posted April 3, 2015 Report Share Posted April 3, 2015 Leather yep..it would have the doughnut/oring....you prolly found the problem...get the shavings out...try again to shoot you got it narrowed down to the bolt/extractor is my guess...there was a post a while back bout the extractor tearing the cases up,,and if im not mistaken he put in another and solved the problem? there was a machining problem on the extractor? :) Wash Quote Link to comment Share on other sites More sharing options...
Dane Armory Posted April 3, 2015 Report Share Posted April 3, 2015 Fixed a couple of these by getting DPMS parts{ o-ring, extractor spring , pin}. Quick fix pull out o-ring and see if it shoots. You will need dental pick, tiny flat screwdriver, tiny bent needle nose pliers a couple of small punches ...And 3 hands. ! Might want to order parts first , spring may dissapear !

LeatherNuts Posted April 3, 2015 Author Report Share Posted April 3, 2015 O-ring pulled hopefully I will be able to get to the range again soon, if not may try a "desk pop" in the backyard. On a positive note I do believe I found the most wasteful shooters on the planet. I decided to pick through the brass cans during target change since i wasn't shooting much,fired 100 rounds and returned with almost 400 empty 308 brass in less then 2 hours.

LeatherNuts Posted April 7, 2015 Author Report Share Posted April 7, 2015 Well i broke it lol. Pulled the o-ring and the issue continued figured "hey why not pull the spring and try compressing it some?". Idiot, spring slipped got bent now it's crap. Will go to the smith tomorrow and pay for stupidity. Quote Link to comment Share on other sites More sharing options...

LeatherNuts Posted April 7, 2015 Author Report Share Posted April 7, 2015 All i have are excuses.

Idk pick one. Quote Link to comment Share on other sites More sharing options...

survivalshop Posted April 7, 2015 Report Share Posted April 7, 2015 I'm going to assume this is a 308AR , just find & order a 308 bolt rebuild kit , change out the extractor & spring assembly . I would also check the Ejector to make sure its not too stiff & moves freely in its compression with in the Bolt face . Quote Link to comment Share on other sites More sharing options...
LeatherNuts Posted April 8, 2015 Author Report Share Posted April 8, 2015 Threw an enhanced AR15 extractor spring in and the weapon hand cycles through a full mag. Will hopefully get back out to the range next week and give a report. Quote Link to comment Share on other sites More sharing options...

Yoda Posted April 8, 2015 Report Share Posted April 8, 2015 My first AR15 build did this and my gas block wasn't aligned properly. I ended up having to back it off the width of a dime. Do you have an adjustable block? Quote Link to comment Share on other sites More sharing options...
LeatherNuts Posted April 8, 2015 Author Report Share Posted April 8, 2015 (edited) The bolt moves all the way to the rear and does lock on an empty mag, it just wasn't going into full lock up front. I'm not on an adjustable right now but it is in the que for upgrade. Edited April 8, 2015 by LeatherNuts Quote Link to comment Share on other sites More sharing options...

Will hopefully get back out to the range next week and give a report. The AR 15 spring may work or you may get failure to Extract or Eject when fired with live ammo . The AR 15/16 Extractor springs are not made for the larger & heavier 308 AR Extractor . The 308AR Extractor & double spring assemble below is from a complete DPMS Bolt rebuild kit I opened up for Photo's , the small spring fit inside the larger one . Not sure if its done like that now , this kit is an old one . You can see the size difference in Extractors & springs , of course .

LeatherNuts Posted April 8, 2015 Author Report Share Posted April 8, 2015 I've been looking for the correct spring, but it's proven harder than i expected. So far fulton and sprinco are the only places I've been able to even find an potion to purchase just the spring. Quote Link to comment Share on other sites More sharing options...

LeatherNuts Posted April 9, 2015 Author Report Share Posted April 9, 2015 (edited) Survival, I really appreciate man but if i could just get pointed to the direction of a known good spring kit I'd buy it. I'd hate to take something you may need late down the line. Edited April 9, 2015 by LeatherNuts Quote Link to comment Share on other sites More sharing options...
