Hi,

We've finally got in the new 7.62x39 bolt and firing pin combo that we've developed.

It has a normal 7.62x39 AR15 bolt which has been reamed in the firing pin channel for a re-profiled and extended firing pin.
This firing pin has a new profile which will strike deeper and more fully than a normal AR15 firing pin, and will be much more reliable in striking for the Wolf and Combloc 7.62x39 ammo.

The pin provides the correct tip protrusion thru the bolt face, and is large enough diameter on the tip to prevent primer piercing, while still striking deeply enough and fully enough.

The bolt has to come with it, because of the mods to the firing pin channel. It is a drop-in fit into any normal AR15 bolt carrier and barrel.
It basically solves the firing pin issues that are common with the AR15 and 7.62x39 ammo.

Materials are the same as used in mil-spec firing pins.

Endorsement of this product from Wolf is expected to come fairly soon, and we have discussed it with Wolf, and they agreed in principle to endorse. So, I would expect to see this happen relatively soon.

I don't have any photos of this system at the current time, because it is so new. But we do have them in stock for $125 for the package.

If you're interested, please call me.

I'll post up some photos as soon as Mack sends them to me.

A review of this system will be upcoming in Small Arms Review magazine, and Jeff Zimba is currently using this package on his MGI Hydra, and is very happy with it.

Quoted: Quoted: You guys always have great ideas, your booth at SHOT is one spot I always look forward to. Still waiting on that Mod stock which uses the solar pannel... I don't think that we're going to make those stocks, but if you want one I can make one up special for you. That was my invention.

I had a use for it, for a specific night application in calling coyotes.

Sounds interesting could someone explain this?

Forest,
Here's a pic of an old prototype from years ago, that I made up for Mack, as proof of concept.


It basically is a Crane stock that I modded with an unbreakable flexible solar panel system laminated onto it, and wired into the battery tubes for recharging batteries on board.
It can do AA, AAA, or R123 batteries.

Sent it to Crane for testing, but they didn't buy it. It cost more than a penny, and they have tons of replacement batteries, and didn't seem to see the value in the recharging if you got out of distance from a resupply source.

I made one for myself and for Mack, and we still use them.
I can do it on any stock with battery tubes, and even on the CAA "saddle" with the battery tubes.

I also have a version which can be a detonator for Claymores, eliminating the "clacker" detonator. Includes a wiring junction and switch on the stock for that version(mil only).

Thanks Wayne!

OMG that is beyond Cool!

Do you offer this conversion if someone sends you say their VLTOR?

Yes, I could do some on a limited basis in my spare time.
Haven't done one on a VLTOR, but it should be possible.
I'd have to permanently glue the removable battery tubes on, so that I could laminate the solar panel on it.
Please contact me privately if you want to talk about having me make one for you.

Quoted: twl, Are there any other improvements made to the bolt except firing pin? I have a DPMS in 7.62X39 and heard a lot about weak bolts prone to breaking. It hasn't failed on me yet but it is like waiting for an accident to happen. Also DPMS extractor slipped on some rims on extraction and after examination the extractor is not grabbing the rim of the case on full circumference, only grabbing at outer edges and leaves marks clearly showing it. I put o-ring in the extractor to increase grabbing tension and it seems work better on extraction but leaves deep marks on the rim upon closing on a cartridge. What extractor are you using on on your bolts? Are they specifically made for 7.62X39 case? My DPMS extractor seems to be an extractor from different caliber bolt. Lastly, do you have any thoughts offering chrome-lined barrels in this caliber /at least as a limited run/? I am shooting russian surplus ammo exclusively /same as wolf/ and cleaning after shooting is no fun at all. And I can see that these ammo can play real hard on non-chromed bore. Davaa

Davaa,
This kit uses a normal grade bolt that is not going to be demonstrably stronger or less prone to breakage than your DPMS bolt.
With normal grade bolts in this size boltface, some last long and some don't, and there can be a variety of reasons, depending on how the gun is tuned, and the ammo pressures.

We really didn't do anything different on these bolts, other than to make the firing pin hole the correct size for this new pin. It's primarily a firing pin upgrade that required the modified bolt hole for it to fit.

Ragarding the extractor, I will have to check with Mack on that one. I'd expect it to be the proper extractor for the boltface size.
Adding extractor tension will cause marking of the case rim as the extractor rides over the rim when chambering. If you are not reloading the cases, then I'd see no real problem with a mark on the rim in these disposable steel cases.
However, I do think that the extractor claw should get a good full grip on the case rim, and that could be an issue. As for right now, if your extractor is working, it's probably ok. I'd look around for a better one to keep as a spare. We don't stock the small parts of this nature, and leave the spares purchasing to the end user.

We have plans for a hi-strength bolt in the future, which is a "spin-off" of the technology we developed for our future .308 kit, and we plan to make the hi-strength bolt in 7.62x39 bolt face as well. But that is still a ways off yet. The price for that hi-strength bolt will be very much higher than normal.

We don't actually manufacture any barrels at this time, and we buy them from normal vendor channels. Nobody currently offers a chrome-lined 7.62x39 barrel, and I don't think anybody has ever offered one. I like the idea, and perhaps we could contract a special run of barrels in this caliber with chrome lining. I can't promise anything, but I'll bring up the subject again to management, and see what they say. I think it's a good idea. The barrels that we currently have in stock are DPMS barrels.

Quoted: twl, Thanks for the reply. I will compare my extractor with regular 223 size boltface extractor. So far besides few feeding and extraction problems the gun shoots fine. The chrome-lined barrel in 7.62X39 will be a real good option for guys intending to shoot wolf or surplus ammo. Besides no one offered this type of barrel before so being a first comer isn't that bad thing too. If the c-products 7.62x39 mags will be successful a lot of guys will be building 7.62X39 uppers.

Davaa,

Glad to help.

As I'm sure you're aware, we are providing a reliable 7.62x39 rifle with our MGI Hydra Modular AR15 system, which can use normal AK47 mags.
So, while it would open up the market alot if CProducts is successful, we need this for our customers anyway.

I'm not sure why nobody has made a chrome-lined 7.62x39 barrel for the AR, but I do agree that it would likely be a popular option.
