Since I'm not sure how to go about setting up a group by, I'll throw up a discount code for 308ar.com members Use discount code: 308AR for a 10% discount on 308 parts send me a PM or email me through my website if you have any questions.

I include them in the rebuild kits because everyone's gun is different and it gives users the ability to "tune" the extractor to their gun.

I'm still here. I've gotten a little less stringent on following this thread since the forum changed over and I can't make sense of what is what. I did call and left a voicemail with survivalshop just a bit ago. Give me a bit to digest everything that seems to be going on in this thread since I last posted.

+1 Don't hesitate to email me at dave@dwilsonmfg.com if you're having any problems and I'll get you taken care of.

If someone can point me in the direction of setting one up, I'd be more than happy to. Otherwise I can set up a discount code for forum members that's good for a given period of time on my website.

Not definite ETA, still have to send them out to get coated.

It's the angle of the picture. There is a chamfer on the leading edge that you can't see clearly in the picture. -d.wilson

If there's interest, please let me know how to go about setting up a group buy on this site, without getting the site staff after me and I can certainly make it happen.

Thanks for the review! Please don't hesitate to email me/send me a PM with any questions. - Dave Wilson

Thanks for the feedback <thumbsup> -d.wilson

Response from Armalite CS: "The only real difference between the DEF10 and A10A4CBF (will be discontinued) is the triggers. Overall the modern sporting rifle design (DEF10, DEF15, and DEF15F) lends itself to modularity not only at the customer level, but at the point of manufacture. By using standard commodity components at those points of modularity we are able to control cost without sacrificing quality. We don’t consider the Defensive Sporting Rifle a “budget” series necessarily, but rather a sound, well-built modern sporting rifle platform that is fully functional in its configuration yet highly adaptive to customer modifications down the road as well. We completed a comprehensive overhaul of our operations including value stream mapping to cut cost in manufacturing times and processes. This is the same processes that will help us launch our other new lines at lower retail prices as well. This added to our increased manufacturing capacity or processing has allowed us to produce the product with less overhead than in the past. In return we passed this savings on to the customer.

I was kind of wonder this myself. The spec sheets on both models on their website seem identical.

My mistake, I mistakenly refer to everything 308 as an AR10. The lower rail height. Shadow ops, Lord of War, maybe one or two others.

Interesting. I'd never heard of this before.

I have a number of AR15 and AR10 billet upper receivers that were some contract overruns (some have company logos on them). They are all 7075 aluminum and are hard anodized. I'm asking $175 for the AR15 ones and $200 for the AR10 ones shipped via USPS Priority.

These should work with all DPMS style bolts and carriers. I know there are a few brands of bolts out there with proprietary extractor/ejector designs that these kits won't work with. I can work on putting together a list to post as well. Any help with figuring out all the brands to look at would be appreciated. No problem. It's you guys that keep the lights on, so I like to keep you happy and give you what you want <thumbsup>

Yessir. You'll get an email to confirm your order and another one when it ships out. Everything gets sent via USPS Priority. I can usually have stuff in the mail within a day or two.

I think I got all the bases covered with small parts kits. There are a couple different kits available at hopefully what's considered a reasonable cost. I did put some complete bolts us as well. Please excuse the cell phone pictures that'll do until I get some better ones taken. http://www.dwilsonmfg.com/store/p24/308_Bolt_Carrier_small_parts_kits.html Extractor Rebuild Kit QTY 1 Extractor QTY 1 Extractor Retaining Pin QTY 2 Nested Extractor Springs QTY 2 Reliability Doughnuts Ejector Rebuild Kit QTY 1 Ejector QTY 2 Ejector Springs QTY 2 Ejector Retaining Pins Gas Ring Kit QTY 6 Gas Rings Bolt Rebuild Kit QTY 1 Extractor QTY 2 Extractor Retaining Pins QTY 2 Nested Extractor Springs QTY 2 Reliability Doughnut QTY 1 Ejector QTY 2 Ejector Springs QTY 2 Ejector Retaining Pins QTY 6 Gas Rings Basic BCG Spare Parts Kit QTY 2 Nested Extractor Springs QTY 2 Reliability Doughnuts QTY 1 Ejector QTY 2 Ejector Springs QTY 2 Ejector Retaining Pins QTY 3 Gas Rings QTY 1 Firing Pin QTY 1 Firing Pin Retainer Master BCG Spare Parts Kit QTY 1 Extractor QTY 2 Extractor Retaining Pins QTY 3 Nested Extractor Springs QTY 3 Reliability Doughnuts QTY 2 Ejectors QTY 3 Ejector Springs QTY 3 Ejector Retaining Pins QTY 9 Gas Rings QTY 2 Firing Pins QTY 2 Firing Pin Retainers QTY 1 Cam pins QTY 3 Gas key screws

I'll finally have some time this week to get the rebuild kits up on my site. Can someone give me a list of parts they'd like to see in one?

Thanks to both of you. I'll try to work up some pricing over the next few days and get some pictures taken to get parts kits/repair parts listed on my site.

Sadly, I can't say that I was on the forum before the comment. I have pretty strong analytic coding built into my website, so I can see where it is link from, demographics of who visits, etc, so I decided to hang out and answer any questions. I've been considering branching out into what I call off-caliber bolts lately as there's been a handful of people that have contacted me about them. It's really not that big of a deal to machine bolts with a larger face, it's more justifying making 1,000 bolts that I'm going to have to sit on for an unknown period until they all sell. 20 ARs, that's impressive. My take on the few spare parts on the market is combination of there are few people making them and compatibility issues. There seems to be a plethora of companies that spring that are making (or so they claim) their own proprietary carrier/receiver set/whatever so that is really muddying the waters of what combination of parts will work together. If the interest is there, I can put some rebuild kits up on the website.

The mechanical properties of 9310 are quite comparable if not slightly better than C158 and generally speaking, make a stronger, tougher bolt when heat treated properly. It's slightly easier to source as well. If I was Continental Machine and Tool (CMT) and made tens of thousands (purely just a guess) bolts a month, I might have economies of scale more in my favor. I make 2-3,000 bolts a month, so I stick to 9310. Simple as that. As for testing, there are a couple schools of thought. The origins of MPI/HPT testing bolts as I understand it, mostly comes from how most manufacturers make their bolts. To make the stops that prevent the cam pin from dragging on the inside of the carrier (and also preventing the cam pin from being inserted the wrong way) most manufacturers stamp the bolt in a large press to create the stops. This creates lots of concentrated stresses in the cam pin area of the bolt, which would make them an excellent candidate for MPI/HPT testing to detect and surface imperfections. I take a slightly different approach in machining bolts. I machine the stops into the bolt and don't press them in so I'm not inducing unnecessary stresses into the bolt by stamping it. The bolt then gets shot peened to mitigate any surface stresses, heat treated, then coated/plated. Some may argue that this creates a bolt that they see as inferior. I tend to disagree. In the past year and a half, since I've been keeping better warranty records, I've had approximately 3 bolts break, so out of roughly ~30k bolts, I'd say that's pretty good odds.

Hopefully I'm not stepping on any toes by posting here. But I own d.wilson mfg. Let me know if you have any questions. Obviously to protect the retailers I sell to, I wouldn't disclose who they are, but would be happy to answer anything else.
