I ordered an ejector, spring, and retaining pin. I didn't want to go through the hassle of tearing apart the bolt without having new parts to put back in it. I'm going to try it once without the $70 Brownells jig (might try to make my own). I was browsing through several part options on Midway (BCG, bolt, bolt rebuild kits, piece parts, etc...) and noticed this review. I wonder if they had a bad run? Midway review:

I pulled everything apart to clean and inspect. The ejector is firm, but moves freely when pressure is applied. I did not attempt to remove it from the bolt. I have a wear mark around the bolt that stops at the extractor (2nd pic). Is this normal? Thoughts and opinions?

I don't have any spent ammo pics (I should have thought of that), but here is the extractor and BCG:

Sounds good to me. When do you guys want to go?

I have a couple threads on this board describing the gun build and several issues that you guys have helped me overcome. Currently, I'm on a quest to find inexpensive ammo that will actually work in my gun. I've been experiencing FTE, often times holding the spent round while attempting to load the next into the chamber. I was mistaken in my last thread when I suspected it was a 7.62 vs 308 issue. After I looked through my Ammo orders, my last batch of "bad" ammo was 308. I have 4 metal DPMS magazines and 2 PMAGs all 20 rounds. I attempted to segregate the magazines to determine if it was a magazine issue, but so far I can only conclude that my gun doesn't like many brands of the cheap stuff. Details below, along with a video of an exploding target. https://www.facebook.com/photo.php?v=10151705859164426&l=7205561078234421217 Prvi Partizan FMJ-BT, 308, 145grain: I used both DPMS and PMAG magazines with this ammo. I experienced 5-10 FTE per 40 rounds. I attempted to shoot full 20 round magazines, 1/2 loaded 10 rounds, 5, 4, 3, 2, and 1 round tests in both types of magazines. The bolt locks back on an empty magazine every time. One of the FTEs occured during a 1-round test. The round just kind of sat inside the gun. Other times it was still on the BCG, smashed against the top or opening edge, or wedged into the chamber with the next unfired round. PMC FMJ-BT, 308, 147grain: Same performance as the Privi Federal XM80C, 7.62, 149grain: 40 rounds through the PMAGs with no issues. Winchester Powerpoint, 308, 180 grain: 20 rounds through the DPMS magazines with no issues. TraJeTech, 308, 175grain: 40 rounds through the DPMS magazines with no issues. Hornady ZombieMax, 308, 168grain: 20 rounds through the DPMS magazine with no issues. Winchester FMJ NATO, 7.62, 147grain: FTE through the DPMS magazines, but not as often as the Privi or PMC. I have not tried the PMAGs with this ammo.

As far as the buffer tube; what are the lengths of each? It was stated earlier that the 308 is 3/4 in longer, but what is the total length so those of use newbies with FTE problems can go measure their guns. Thanks!!!!! :auto:

I picked up 2 from Midway a couple weeks back. On a side note; I was at Shoppers and Dicks this week and both had ammo. I texted a buddy of mine because he was lookiing for 22 and he replied with, "So does Sportsmans!" I wonder if things are returning to normal??? I actually passed on the ammo at Dicks. They didn't have the 9mm brand that I want and their 308 was either too heavy or too light for what I need at the moment.

I got a reply from CMMG and will try playing with the BCW and AMMO types on the next outing. Here is my reply from CMMG <thumbsup> :

My barrel is CMMG.

I just read through this thread and am still a little confused. My barrel is stamped 308. Could this be my FTE problem?

This is my next attempt at cheaper AMMO. I'm headed out with some friends a week from this Friday and will let you guys know what happens.

Not new, probably has 500ish rounds through it. Can I be creating an issue running the Heavy Buffer in conjunction with the Tubbs BCW?

Quentin Defense lower, CMMG upper, Tubbs BCW, Heavy Buffer, PRI Brake, CMMG Lower Parts Kit, DPMS tube and stock. I've used multiple brands/grain 7.62 (Winchester, Privi, and PNC). The Winchester jams the least from the cheap stuff. I've also used multiple brands/grain in 308 and NEVER had a jam. I think the lightest 308 was a 160, and 147 for the 7.62.

Would there be any reason that my gun would jam (FTE) with 7.62, but not with 308? My 308 ammo is higher quality, but I just want to make sure that I'm not missing something. I've tried multiple brands of the cheap 7.62, all brass case, and used both DPMS and PMAGs. Thanks, Greg

I'm thinking about hitting the range this Thursday or Friday. Does anyone want to play hookie from work?

Bump! I'm going again tomorrow around 9:30. I want to try out my new muzzle brake.

Sorry that I missed it guys! On a side note, if you took the I-10 from Phoenix to Casa Grande, you passed my happy ass while I was stuck at work (F'in taskforce at work)... Charger rides still available until it gets hot! Josh, good luck and thanks for your service!

Factory finish was more of a nickel. I had to polished mine to match the barrel. Off to the range tomorrow or Friday!

That's what I figured, but there are videos all over youtube. I haven't seen one on a .308 yet. It has to be a hand full!

Has anyone played with a Lightning Link?

Do you have a storefront? I was under the impression that you just did custom work and not really much of the parts retail side. I prefer to shop local and apologize for not thinking of you first!!! Just didn't know that it was an option for little stuff like this.

I'm trying to get off from work. If we go on a Thursday or Friday, I'm in for sure as those are my normal days off! I'm bringing a lot of water and my .308LR. The charger would cost a small fortune to drive to Casa Grande; so I will bringing it to lunch if we pick somewhere in the east valley (San Tan brewery is good food and beer, and Cogburns has good food and is a little on the dirty biker bar side of things if that's more like our crowd. I'm open to anything, just a couple suggestions.). Summary: and for food: Santan: or Cogburns:

I ordered the PRI in stainless.

Heading to Usery tomorrow! I have a friend or 2 meeting at my house in Gilbert at 9:30, and we should be there shortly after 10. Feel free to post, pm, etc... if you want to join. Greg

My little girl got sick last week and I wasn't able to go. I'm going to try to head out this Thursday if anyone is interested in joining.
