05... I had a similar problem with my build, maybe not exactly, but similar. Just spitballing here but my hammer spring wasn't installed properly which wasn't allowing the hammer to cycle correctly. I installed it correctly (after Wash pointed out the problem) and it runs like a dream. Maybe take a pic of the trigger assembly and make sure they (springs) are installed correctly...

Welcome from Delaware... Been in the pits a few times at Dover Downs.. I live about 35 min south of Dover...

Welcome from Delaware...

Welcome from Delaware... When I built my lr308 I ordered my barrel from rainier arms. I sent them my bolt and they checked the headspace for me. I'm sure if,you order your barrel from a reputable dealer they would do the same. This is the place to ask questions, lord knows I had many along the way and was greatly helped by the members of this site. Feel free to ask away..

I just ordered 1000...255 regular price but 204/1000 with that coupon code.. Free shipping... Good deal. Thanks Cali.. I'll report back when I get them in.. Hell of a deal I thought.

Agreed, they are for a 30-30 application... Didn't realize the difference in OAL when I ordered them.

I'm using BLC2 powder sketch... Mike.. Do you think there will be any chambering issues? I only got these to plink in the back yard but I definitely will not be buying again.. not a reflection of the product, just a lack of foresight on my part...

Sorry.. The bullets from xtreme are 150gr. Flat tip...

I have been reloading for a few years now, mostly pistols, but I am now doing .308 and .223 for my rifles. Bought some Hornady 160gr. For $29/100 and they work great. I have been buying from Xtreme bullets for all my pistol bullets and have been happy with their product. Long story short... I ordered some .308 160 gr. Bullets with a roundish flat head. After I loaded a dummy round (no powder or primer) I noticed they are considerably shorter than the pointed Hornady bullets. I can't seem to find any data to help me find out what comparable load I could use. I have attatched a pic of the Hornandy in my caliper and one of the xtreme bullet as well. Any experience with these bullets? I don't want to over pressure them by placing them too deep nor do I want them just in the casing. Didn't even consider these bullets might not be acceptable on the AR platform. Any and all help is greatly appreciated.

Well I wanted to follow up with you all and give you the latest.. Got home, grabbed my 308 and went out back to see how it worked after the adjustments to the trigger system. First shot, open breech, bolt locked back like it should, casing at 2 o'clock and 10ft away. Loaded mag with 3 rounds, engaged the bolt... Bang, Bang, Bang.. All 3 shells landed within 1 foot of each other. What a relief!!! Gun shoots as smooth as butter, no hiccups and truly a joy to finally shoot. I want to thank each of you for taking the time to help me trouble shoot my issue. A big shoutout to Wash!! Thank you guys again, it is nice to belong to a forum where everyone is soo willing to help out.. Thank you all again, couldn't have done it without all the help!! I will get it cleaned up, scope mounted back on it and post some pics of it soon...

Thank you Wash... Adjustment made...

First spring pic is dpms, second is JP Spring. Longer buffer is 3.25 inches and weighs 84 grams, shorter is 2.5 inches and weighs 108 grams.

Ok boys here it goes... I took some pics of the requested info but I noticed when I was taking a picture of my trigger assembly, the trigger spring was above rather then under the trigger (what a dumbass for not double checking when I assembled the first time) so I reassembled the trigger assembly, put and empty mag in, pulled back the charging handle and the bolt stayed open... Imagine that... By the way..only used the JP spring on trigger, not hammer spring, it is original DPMS hammer spring. Here are the pics of the buffers, springs, and spring depth. I also took pics of the trigger assembly, the bolt catch with a mag in and one with no mag. I think the trigger spring blunder was causing a lot of my issues.. I will fire it this Thursday or Saturday and report back...

sounds like a plan. I will get the pics together tomorrow after work and get them posted.

Thank you Survival for the input, the ejector pin cannot be pushed in with my finger but i can push it in with a casing if I slip the base of the casing under the extractor and rock it back until casing is flush against bolt face. I did what Wash suggested but took it a little further. Just got done totally disassembling, cleaning and reassembled gas block, tube, and bolt. Went for a test fire with a new PMag... Single shots with mag in will eject casing 10 feet away at about 2-3 O'clock but with 2 shells in magazine, bolt will pick up second shot but firing pin doesn't engage... pull the trigger and hammer isn't "cocked".. I did change out the JP Polished buffer spring to the one that came with the DPMS handle assembly. Making some progress here but..... A few side notes... The bolt catch pin doesn't hold when i manually open the breach, I can get it to open but if I move the rifle, the catch pin release and the BCG slides forward to close. I also noticed that when I was shooting single shot from mag, BCG wouldn't lock open but I could slide it back and BCG would lock open with empty mag. Syrnac Adjustable gas block is fully open so I don't think it is under gassed. It is a DPMS 308 lower build kit so Im assuming it should work properly.. I am running a Black Rain Upper/lower set. I checked the way the BCG slides in the upper and there is no interference between gas tube and gas key, slides smoothly Do you think the new buffer spring isn't stiff enough to send the BCG fully closed after rifle is fired? With all your help, I am getting to the bottom of this and I appreciate everyones input and time to help me figure this out...

Lol... I will keep the rifle bj on the down low... I am running magpul magazines... I will let you know ASAP when I'm done with the air test... Thanks again...

Wash.. Thanks again for the help and I haven't done the air test yet, my neighbor has my compressor but I will get it back tomorrow when he is home. When I run the air test do you suggest a rag or something in the chamber where the bolt would go or should I take the bolt out of the BCG and try it that way? Also another thought I had while driving home from dinner... When I shot it for the first time yesterday I had to take the mag out to get it to lay in the lead sled... It cycled fine... When I shot it the other times there was a magazine in it.... Does that make any sense? I have spent some time replaying this whole incident in my mind and it just dawned on me about the magazines...

Are there issues with the JP Springs? I did notice today when I was cleaning the ejector pin that it is pretty tight. I can push the pin in on my ar15 but not on this 308. How much resistance should be on the spring? Should I be able to compress it a little with my thumb? I could cut a coiI off to lessen the resistance. I have read numerous discussions on the Shadow Ops BCGs... I sent the bolt to Ranier Arms for headspacing when I bought the barrel so I don't think that is the issue that I am having. I'm going to order a new extractor but they are back ordered. Anything else I'm missing? I am trying to trouble shoot this issue one thing at a time. Thank you for all the responses and suggestions so far.

So a little more testing today... I looked through my receipts and the spring I am running is a JP Enterprises polished carbine spring and a standard dpms carbine buffer. I took apart the bolt assembly and removed the extractor pin, cleaned and oiled, and reassembled. Soaked the BCG in mp7 oil and loaded one round in the magpul magazine. When I fired the round, it did not eject and I had to pull the charging handle pretty hard to get the spent casing out. Research and testing ended at that point as the frustration got the best of me.... The rim of the casing is scratched up but I can't tell if that is because of the ejector or a result of the bolt cycling back onto it.

I thought I read somewhere that the heavy buffer was a must for 308.. I still have the original that I can change out. I'm shooting 147(?) g ammo from Wally World. I have the equipment to reload my shells.. Just eating up trash for the brass.... I have not tried the air test but will do tomorrow. I'm gonna try some mobile one oil and run the BCG wet. Is it possible that I have over adjusted the gas block and am getting to much gas back which is causing the BCG to move to fast?? Just spit balling here.... Has to be a simple solution that's why I'm relying on you guys!!! Love this site and the wealth of info and willingness to help others out..

hello all... After completing my build a few months back, I finally got out today to dial in scope and send some rounds down range. I quickly found out that I was having issues. 1st shot without mag (had gun in a led sled) went fine. Second shot free hand casing did not eject and new round in chamber with spent round. Figured it maybe a gas issue so I adjusted the Syrac block with a single round until bolt locked back. Next few shots casing would not eject, just laying on top of magpul magazine. Last shot, casing still in chamber, new round jammed against spent round, not completely striped from mag. I am running a Shadow Ops Weaponry NiB BCG, heavy buffer in a Black Rain upper/lower with a Rainer Arms Ultra Match Barrel. Running BCG well lubed but not dripping with oil. Ejector spring seems fine and ejector pin has good tension when pushed in. Any and all help is greatly appreciated...

Hello all, Ordered this last Winter but got a different one from a friend who was changing his. New in box. List 189.00 Looking for 150.00 OBO Im open to reasonable offers. Here is the link to the Website and product description. You can call of text me @ 302-542-FIVE-ONE-60 for more info etc. Can accept money orders/Cashiers check etc. Not a business, just a fellow .308 enthusiast. https://www.midwestindustriesinc.com/index.cfm?fuseaction=category.display&category_ID=1209

After finally getting to assemble my 308, I noticed micro scratches in the finish of the matte ss barrell. They are from the barrel wrench and gas block. As careful as I was, there should be no reason for these marks. Never had a matte ss barrell before. Is there a way to remove them or is this something I'm going to have to live with? Any help greatly appreciated...

Agreed.....
