Since I don't have the tools to do that, guess I'll put it back together and let the pawn shop dude handle it. If he can't figure it out then I want my money back. I will point him to this thread.

There isn't a K in the serial number. So I assume its factory as I have the box it came in and the serial number on the box and lower match.

Ok a few more pictures for you peeps. In the 1st picture on just my eye balling, I think this is where the block and tube should be to align which is a little different from the setting they installed. But that would make the gas tube even shorter in the upper. In the second picture if you can tell, the indents in the barrel are way off from the alignment holes of the block. I am wondering if they installed the wrong block on this setup. I mean I would think the barrel indents would mean that's where the Allen screws should go when tightening. Maybe I'm wrong. I had to file the barrel a little bit just to get the gas block back on... WOW.

And one more. Look at the stake marks...

Some pictures for you.. Looks like it's 9 3/4" to me, I put it ~ where you said it should be an it was ~ 3/8" off. Making the total length 10 1/8"???? That's not a listing. lol Does look like some blow by on the tube.

AH I see your point survivalshop on the mid hence 16" barrel. 11 3/4" it is.

Oh man, you mean I bought a FORD DPMS rifle? CRAP!!!

I see what you mean now survival shop. It does appear short by that photo you posted. I am not sure what to compare it to the apple or the orange. But I will take it apart and measure it best I can. I did speak to a DPMS rep and he pretty much didn't want to say anything since it had been modified a bit. SO that was of no help.

I have to find out about that length from DPMS. I have made sure the gas rings were staggered. Thanks for your replies.

I know the area well I live in Randall county. and have a farm in Wheeler county so we drive through Pampa often. I am just getting into shooting and haven't fired ant type of weapon since basic. LOL Now thats been a few years back. I have never had a need to own any type of gun/rifle until lately and thought I better get something before it's to late. You got that right bud.

Hi all, I live up in the Panhandle not nearly a nice as hill country area.

And now some pictures. Hopes this helps you guys out. The barrel had DPMS 7.62 x 51 1-10 stamped on it. The gas block was tight no signs of leakage. The only marking I could see is an A. I am not sure on how to check the alignment though.

Appreciate it peeps and will let you know what I find after closer inspection. I want AMMO if a part he install is wrong or bad and make him fix it. Make sense?

I wish I knew what gas block it had on it, if he even changed it. I'll have to ask him tomorrow when their open. I do plan on talking to DPMS tomorrow about it via phone. Just one more thing now that I though of it, AMMO, I am using (on the cheap) some Perfecta 147g FMJ and some like 150g Winchester rounds Neither make any difference.

Thanks for the reply... Yes, with a mag in place, I can manually lock it back and then it travels a bit more if I pull the charge handle after lock. That's without pushing the thingy in the side to lock it, if that's what you mean.

Thanks for the reply! In answer to your questions... 1) Are you able to remove the rail to expose and examine the gas system? - I have never actually done it but I assume it's only some screws holding it on. Then what do I look for? 2) Also, pull the upper and slide the carrier in and out by hand. Make sure it moves nice and smooth, and that the gas key isn't hitting or binding on the gas tube when it closes. - I looked at this earlier today and I couldn't tell one way or the other. Looks clean to me, but I will inspect closer. 3) One thing I do with any new 308 build is start with one round in the mag. Do this a few times to make sure it locks back. Once you get that situated, put two or three rounds in. Its easier to troubleshoot one problem at a time. - I have been fighting this thing for ~ 3 months off and on when I can, probably ~ 5 outings at most. Most rounds I have ever had in a clip is probably 5. I usually do 3 cause of the problems. At first did try 1 round at a time with the same results, but haven't tried since. I am just trying to gat as many rounds through it as possible right now. Unfortunately I will not be able to try it out again with one round for a couple of weeks. So what would you suspect if one round doesn't lock it back?

I have one DPMS mag and one Magpul, both do the same thing.

@blue109 No I did not. It was new and the dude at the Pawn shop did all the mods before I took it home.

Hi all new to the forums and have a question I am sure has been addressed numerous times. I have never owned a weapon of any kind and only ever really fired one was back in Basic Training. I just never felt the need until lately. Anyway, I bought a DPMS LR-308 new at a pawn shop. I had the guy build me little better weapon. He suggested I put on a Troy ~13 3/4 rail, change to a Magpul ACS stock, said something about a gas block change( I have to confer with him to make sure) and added a Truglo three color Dot site and a Sight Mark Green light laser/flashlight. Now the problem I am having is feeding/cycling (BCG oiled wet) as well as last round the BCG doesn't lock open. I have taken it apart cleaned lubed and tried again numerous times with the same result. I realize having only ~ 75 rounds through it that could be part of the problem, since their chambers a tight and rough from what I gather. That party as aggravating as it is, is not my main concern. That would be the bolt locking open on last round. With a mag in place I can lock it open so that seems ok. I have taken apart the buffer assy. and measured the buffer, buffer spring and magpuls buffer tube depth as well as the buffer weight. They are as follows. Buffer Length - 2 1/2" Weight - 3.8 oz Spring Length 11 1/4" Coils ~ 27 - 29 depending on how you count LOL Magpul Buffer tube depth - 7" best I can tell. Any ideas/tips
