Damnit! I hit the wrong emoji...

Well I may not have much build experience...but I do got some practice stuffing big things in small holes!

Yea I guess I'm going to change the buffer spring and see what that does. Unfortunately my hole in the wall town doesn't have a gun dealer, the town next door has a couple but they don't carry much build parts and since I'm going to have to order something I'm going to give the tubbs Spring a try and see what that does, plus it's another fairly inexpensive item that could straighten me out hopefully. One more thing I was wondering, I've owned a couple ar 15's years ago but I really can't remember but I believe they were a lot easier to pull the charging handle back. Are 308's supposed to be that much more difficult to rack because mine seems pretty stiff?

Ok that's how I had the spring but I was just making sure. 11 1/4 you say? Ok yea I was using an empty case to move them.

Also is the buffer spring supposed to go all the way up on the shoulder of the buffer to where it butts up against the head or is it supposed to butt up to the shoulder and that's it?

Ok so it's getting quite a bit of air thru the tube, I'm fairly certain that I've got the gas block where it's supposed to be. The receiver extension tube inside depth is 7" on the money. The buffer is 2.5" in length, I don't have a scale to weigh it tho. But my spring is only 10 7/8" long and it has 27 coils by my count. Washguy, I dong have any of that polish but I'll look into it. And also thanks for that PRO tip earlier even tho it's got me making a dentist appointment now... Anyone know how tight the ejector and extractor should be? Should I be able to press them with my finger?

DAMN IT!!...I chipped a tooth!!

I'm at work and the guys are looking at me like I'm crazy after reading that, had me on the ground rolling lmao. I promise I've cleaned it since those pics, they were taken right after shooting with a quart of mobile 1 in it...I mean everybody on here keeps saying sloppy so that's how it got it, SLOPPY! I'll get all that other info later this evening. Preciate the help.

Ok so got the gas tube swapped out to the armalite tube and still no change. I can't get thru 5 rounds without a jam. Also had a few cases that did not fully eject, they bounced back into the receiver, that's never happened before. Not sure where to go from here. Buffer or spring? Mag catch? Trying some different mags?

Defenitely will be upgrading the optics on this thing! I had never used a variable magnification scope before and wasn't sure how it would be. Nothing against the Athlon, decent for the money, but for sure want to stretch it out some.

I've got nothing but great things to say about Faxon. They were awesome to deal with when we were going thru this recall stuff. If I sent an email, they got back to me asap. Even threw in a free muzzle device for the troubles. I've heard a few of the guys from Faxon speak on some podcast and they just seem like good people. Top notch customer service!

Enough said! I've seen you guys on here regularly for a long time and watched many topics unfold. I will try it out and let you know what happens. Thank y'all!

That being said...what now?

Awwwe...it says on their website on the specs for that barrel, beside barrel extension, dpms compatible, that's probably why I didn't look into gas tube length, I saw that and wrongfully assumed dpms everything for it.

Thanks, i'll defenitely look into that. So it's too short and not fully blowing the bcg back far enough? Or what?

Looks like tube is about 15" best I can tell. Here's a few pics that might help. yes, yes I know it's dirty than you know what but I haven't cleaned it since I added a quart of motor oil to it this last time. I don't always get to do, what I want to do, when I want to do it, when you got 4 critters running like a bunch of crazed animals, lol! As far as the mag catch goes, I used the one that came with the Aero lpk because it was supposedly longer or something but I could have tighten that thing in until it was below surface of the receiver.

Sorry I just saw this after I started a new topic, sorry I'm behind times when it comes to forums and threads and chats, bare with me please.

Ok so I've recently completed my first build. Alright everyone here is my first build parts list: Aero Precision M5E1 stripped receiver set w/15" Aero mlok rail Aero lpk Hexmag pistol grip Aero .308 carbine buffer kit Magpul ACS-L stock Faxon 18" rifle length medium contour barrel Gamma 762 muzzle device YHM gas block Spikes gas tube Athlon 1-4x24 scope Everything went smooth with the build process. Took it to the farm and was ready for the break in. I took advice from posts I had read and used mobile 1 and got everything sloppy. I loaded one round into the mag, chambered the round and fired. The bcg locked back on an empty mag every time. Then things went to crap. I'm getting bolt over base malfunctions, it's totally random, doesn't matter if the round is getting fed from right or left side. I have 2, 25 round pmags. I have tried multiple types of ammo, including different manufacturers, different grain, 7.62x51, it happens with everything. I received an email from Faxon saying there was a recall on the barrel I had so I thought that might be the problem, sent in the old, installed the new one, still happening. I don't know where to go from here. Any insight would be greatly appreciated and I'll try to answer questions to the best of my ability. Thank you

Thanks, I agree. I don't have any prior experience with any parts manufactures but I am very pleased. I feel like they make a very quality product for the price.

I went with the nitrided bcg, barrel, blacked out everything, I love that look

Ok thanks, I'll look into that. Should I post in this topic the problem I've been having or start a separate one for that?

Alright everyone here is my first build parts list: Aero Precision M5E1 stripped receiver set w/15" Aero mlok rail Aero lpk Hexmag pistol grip Aero .308 carbine buffer kit Magpul ACS-L stock Faxon 18" rifle length medium contour barrel Gamma 762 muzzle device YHM gas block Spikes gas tube Athlon 1-4x24 scope I think that's about it. I tried to keep as many of the main components from the same company. I know compatibility is few and far between when it comes to .308s, so I thought this bring my first build would keep things a little simpler for me. I had a lot of fun researching and buying parts for this thing. And the build itself wasn't near as difficult as I thought it was going to be. I'll let a few people get a good look at the list, then I'd like to get into some technical difficulties that I've been having out of it. Thanks

Thank you all for the welcomes. I didn't really get into a whole lot of .308 talk last night but just to fill in a few gaps, I just finished my first .308 build which in fact was my very first ar build ever. I wouldn't say that I'm a noobie when it comes to guns but as far as building it was a different world. Within the first couple weeks of beginning to research parts, I was HOOKED! Oh boy, this is not going to be good, I thought to myself and my ole lady saw a change in me too. Every moment I wasn't working or had an opportunity to sit down I was researching or reading or looking at something that had to do with building. I have seen where some of you have warned new builders of the bug before, well I tell you, I got it! Anyways I will post my parts list and build in the appropriate section but I also I have run into some problems so I will also be starting a topic on that. Thank you all again for welcoming me.

Big hello from Kentucky, to all the .308 community!! I want to first give a shout out to all those who are currently or who have served in any way to defend the greatest nation in the world! And to those who made the ultimate sacrifice, my family and I will be thinking of you this Memorial Day weekend. It feels good to finally be a member of this forum. I have been a frequent visitor for sometime now and have gained lots of knowledge and insight into the .308ar due to this forum, so thanks to everyone on here for that. I am new into building and look forward to conversating with you all.
