boostless

Have had this out to the range a couple times now and it seems something goes wrong with it every time. After fixing the buffer/spring problem shots were all over the place, double checked the scope/mount tightness and it was fine. Took it back out again Friday night and the bolt catch broke. Decided to keep shooting it since it doesn't affect function. Ended up getting brass in the bolt some how and locked it up. Was able to get it apart when I got home, cleaned, and inspected it. I didn't find anything else wrong with it. I'll have to get a new bolt catch and see what goes wrong next...

not for me, its lefty or no shooty. Motorcycle accident...

I think it would be great if us lefties didn't get neglected...

I got the replacement spring and buffer in today. Slapped it in and the bolt is going back all the way allowing the bolt catch to engage the bolt face. The bolt catch could engage a little further up when engaged by hand. When an empty mag pushes it up it goes up quite a bit more, it will be fine until I get the money to replace it with something better. The replacement buffer looks to be the same and the spring has 28 coils and is 11 1/2 inches. Looks just like the pic survivalshop posted. Thank you all for your help on this.

I appreciate the thought, let me see what they end up sending me and I'll go from there. It's no big rush as I don't know when I'll even get the time to go shoot it again.

I'm going to be taking their spring, I am kinda tight on money right now so I don't know when I'll be able to afford a new spring. Income in my house has been cut down to the point I don't know if I'll be able to pay my bills right now.

I haven't been able to find anything similar so I'm gonna wait to see what they send me. The SASS as far as i know has a rifle length system on it so it wouldn't work for me since I'm running the carbine system.

DPMS said that I had to deal with the company I bought it from. I sent them an email and received a reply back stating that they were going to get the correct/new buffer and spring out to me. Hopefully this will correct the problem, I will update when I receive the new parts. Thanks for the help.

It was seated all the way when I pulled it out. I emailed DPMS for a wild chance to see if they would do anything for me. If not I will probably hold off on ordering anything untill I have the money to get the upgraded buffer as well.

any recommendations as I start looking around?

So it's not going all the way back. I had my wife stick an allen wrench in the little hole on the buffer tube and it went in about 1 3/8 in. so I think with the thickness of the end of the buffer tube it still has about 1/2 to 3/4 of an inch to compress. I didn't have actual grease but I used some engine assembly lube to test and it wasn't compressed/squished/spread out at all.

I'll give that a check when I get back home, gotta go pick up the wife from the airport.

There is nothing I can do to get the bolt back far enough to have the bolt catch engage the bolt face with the buffer and spring installed. I can get it to lock back with the bolt catch on the carrier body, where the bolt inserts, but not on the bolt face.

I'll wait to hear back from guru with the info on his spring before I start looking into new springs as I'm a little tapped out on money right now.

Okay, I thought that was the relaxed measurement but when you said to get the relaxed measurement I wasn't 100% sure. The buffer is good to go right? at least with the length?

Thank you Guru, I know it's not a great brand which is why I'm annoyed that's what everyone keeps pointing to. 98, how do I relax the spring? When I got that measurement the spring was just sitting on the table.

If you can't give me a reason that it's the bolt catch then please don't mention it. It is not causing the bolt to stop it's rearward travel. Yes, I have tried multiple pmags. I ordered a 308 buffer tube kit so all the parts should be for a 308 and I gave what measurements I have. The bolt does not travel far back enough to get to the point where the bolt catch can even engage the bolt face.

I'll wait to hear from others because I don't think it's gonna break in to allow the bolt to move back another half inch and the bolt catch will lock the BCG back on the carrier body.

round count is at 10. LPK was a CMMG. I'm not gonna jump into the AR-10 bolt catch yet. The bolt has another half inch to move back before it's even capable of being engaged by the bolt catch when pulled back with the charging handle. It cycles just fine when firing the only problem I had with the cycling is getting the first round chambered after that it runs fine. I would say that the bolt was pretty wet, I had oil seeping out between the receivers.

I posted this in my "build thread" but want to bring it out to clear some things up. My bolt will not go back far enough to have the bolt catch engage the face of the bolt. The rifle will fire and cycle with out a problem it just won't lock open on an empty mag. Test firing was with a 20 round magpul mag loaded with 5 rds. Parts are as follows: Aero upper/lower set Aero BCG DPMS stock set: http://www.buckeyetactical.com/dpms-buttstock-assembly-6-position-collapsible-lr-308-ar-15-carbine-synthetic-black.html Magpul mags Charging handle is just a standard one: http://www.surplusammo.com/ar-10-lr-308-charging-handle-complete/ The measurements on the buffer stuff: Spring measures 10.5 inches just sitting on the table and has 38 coils Buffer measures 2.5 inches including the rubber end piece Tube depth is 7 inches Any help would be appreciated since the buffer system is what really confuses me on these rifle systems.

I bought the DPMS 308 kit http://www.buckeyetactical.com/dpms-buttstock-assembly-6-position-collapsible-lr-308-ar-15-carbine-synthetic-black.html that's where I bought it from.

Upon further tinkering, it looks like my bolt isn't even going back all the way. This is assuming the LR-308 bolt catch actually catches on the bolt face like the AR-15 does. It looks like it has an additional half inch to go back.

Well I got my BCG in yesterday. I promptly took it apart and checked the headspacing. Everything checked out and I had a chance to get out to the range this morning. I only ran 10 rounds through it but it cycled well. I also took out my fresh AR15 build, this cycled pretty good as well. The bolt was a little tight in the LR308 rifle, which didn't bother me much. What did bother me a little bit is the ejector was very hard on it. I had to pull the bolt back and released on the round in the chamber to get it to lock. Is this a normal thing with the 308s? Once it was locked in it was fine and would cycle flawlessly after the first round was chambered.

no, it causes cancer...

Got the shipping notification for my BCG, should be here by next friday since I'm on the opposite coast...
