Sweet thanks.  I was looking at the melonite gas tubes from Spikes but wasn't sure if AR10 needed anything more specific.  First build and all...

Im getting the Melonite spikes tube. But mine is rifle lenght. Melonite just adds a bit of protection, and should make it easier to clean if you ever do deep cleaning like that. I do every 500rds or so.

Just started my MATEN build and came across this thread. Did a little reading and am wondering what BCG's are working best. From what I have read looks like there are some issues with the 762 Industries BCG. Planning on running a Rainier Arms Ultra Match 18 inch barrel. Just trying to avoid any unneeded stress on my end.

I have not heard of any issues with the 7.62 Ind. BCG's. Some are not happy with the machining marks on theirs but I haven't heard of anyone having problems who actually shoots them. I have 250-300 rounds through my MATEN with that BCG and the inside of my receiver still looks new.

JP also makes a good BCG. If I ever changed carriers, thats what I would go with.

Any issues right off the bat with the 7.62 Ind function? I thought I read a few pages back that some people where having issues with them at first break in.

IF....I go the JP direction I understand that its more than just the BCG that is needed. You need the JP Buffer Spring, Low Mass buffer and the BCG carrier and bolt. Am I correct?

I've got a slew of parts on order and starting to arrive, but I still have a few gaps in my parts list that I'd like some clarification on.

I have ordered the monolithic Maten upper and a barrel from Fulton Armory.

1- I still need a barrel nut, are all DPMS-type nuts equal?  Just order one and that's it?  I want to make sure it works with the upper.

2- will I need a .308 specific gas tube or is any rifle-length tube adequate?

3- What is the advantage of the AR-10/.308-sized stock compared to the AR-15?  I want the Magpul PRS, maybe I screwed up but I already got the buffer and spring from heavybuffers.com.  I got the CAR10 XH for use with a 7" extension.  I don't know what the AR-10 PRS length is or why I would prefer one over the other.

4- I have no clue which trigger I want.  I think I'd rather read the tax code than try to figure out what the differences are between all the Geissele triggers.  Any suggestions?  This is a precision rifle for long range but will be used in the field a lot more than at the bench.

5- I already ordered a low profile gas block.  Will I need to either return it or upgrade to an adjustable block to use a suppressor?

I really like the SSA in mine, but some say spring for the SSA-E, for mostly field work I would say the SSA will work great.



5- I already ordered a low profile gas block.  Will I need to either return it or upgrade to an adjustable block to use a suppressor?  If you want to go suppressor and don't want a single shot, I think you need the adjustable, besides 308 gas can be finicky so having the adjustability will work out any of those kinks.  But I am no suppressor expert.

Armalite AR10 Rifle length gas tubes are a little bit longer than the AR-15/LR-308 rifle length gas tubes.  The one you need with depend on your barrel.  Usually if the barrel extension is patterned for DPMS then it should be the std. AR-15 rifle length.  I think it is always good to check with the mfg.

I guess some people were having issues with sharp or jagged edges or bad machine marks. This was one of the first BCG sent out so I don't think they were in a hurry on this one. You can see some VERY FAINT machine marks if you look really close but your fingernail cannot feel them. No jagged or sharp edges, no worries here. It works flawlessly as well.

Pics for proof.

Thanks for the info. I am not concerned with a few marks here and there. My guns are not safe queens. I know that in time they will get scratched and nicked so its not a concern. Just don't want to deal with function issues. I am currently trying to figure out if I will go the direction of the 7.62 ind BCG or a complete JP bolt, buffer and spring setup.

My BCG from 762 Industries seems similar to the one in your photos.  Some light machining marks in a few spots. But they are hard to see and will not affect the function of the rifle at all.  I'm happy with my purchase.

I was able to find a 762 BCG that was made by Rainier Arms. The 762 Ind looks very similar. Does anyone know if these are in fact the same BCG? Does anyone have any experience with the Rainier Arms NiB Match Grade.308 BCG?

It doesn't matter. This is well documented in the "I'm Not Happy With My Rainier Amrs Match Grade BCG" thread in the AR Variants section.  The bottom line is that they appear to be 100% identical in fit, finish, and function.  The assumption is that all of these companies are sourcing these things from the same "manufacturer" and slapping their own brand name on them.  And at this point, I think that's a very safe assumption.  That being said, I've not seen single report of these BCGs not working correctly.  e.g. They work as advertised.

I got it as a Rainier. However, they seem to have the same parts and shotty finish.
100% functional though.

I bought the Rainier first, and it looked identical to the ones people had issues with from 762. Supposedly the first batch they did was not as bad as the ones out there now. You could run your finger down the sliding surfaces and it looked and felt like a rough file. It did not slide in the upper smoothly at all. I returned it and bought one off of Gunbroker from fox valley firearms....slick like it should be.

There are photos of one these carries messing up a MATEN upper and taking the hard anodize off and eating away at the upper.  Not all of them are bad , only the ones with the incorrectly machined bearing surfaces.

I'm running one of these BCG's that I polished with some 3.5 micron diamond paste and removed a great deal of the zing. I must have missed pics of the damage to an upper. Do you have a link?

I'm not an AR pro, but I assume given enough use, pretty much all AR-type rifles eventually wear through the anodizing were the carrier bearing surfaces ride.  Am I wrong about that?  I ask, because when I previously asked a question about a wear mark in one of my AR15 piston uppers (unrelated to these 308 BCGs) here on AR15.com , I was told that it does indeed happen given enough time.

I had some small anodizing flakes come off from my upper with the "762 Industries Brand" just by charging it a couple times and never even firing it.  These BCG's are a mixed bag, some get lucky and some don't.  I think it depends on how early or late in the production the BCG was run off.  One thing is clear to me after handling a few of these things and that is they all come from one source.  Rainier Arms, 762 Industries, WMD Guns , Lord of War, they all have the same identifying marks.  Mine was really bad IMO and my bolt was out of spec by as much as .006" on some of the lug lengths so it would never headspace correctly.  If your headspace checks out and you feel comfortable enough using it then go ahead.  It's true that the anodizing will wear off over time but rough bearing surfaces will accelerate the wear process.

I started a thread about my supposed Rainier Match Grade NiB BCG and how awful the fit and finish of it was.

After many phone calls to both AIM (who markets the BCGs as a Rainier product) and Rainier, the latter informed me that these BCGs are made by 762 Industries. There's no such thing as a Rainier Arms produced .308 BCG. Period. They've since changed the product name on Rainier's website as well.

Why not? Because a few people got some bad carriers? I have one from JSE thats a 762ind and its flawless. All companies muck up things. Give them a chance instead of running away from a company that is trying its best to deliver BCGs when EVERYONE else in the industry is keeping them for built rifles.

CMMG and DPMS are GTG.  I have a CMMG right now and it's way better quality than these subpar NiB BCG's.  If you want NiB you can always send it to WMD Guns and they will strip it down and coat it.

I'm glad that you had a positive experience and that your BCG worked out for you but a lot of people out there got hosed.  762 Industries is already out of business after only being around for a few months.  They sprung up from nowhere and only sold 308 BCG's and now they're gone.  Shady business if you ask me.  I also think they were the reason I had my credit card number stolen and used for over $2,000 in airline ticket purchases.  I can't prove this but it was the first time I had used the card in months and then I get a fraudulent charge.  I have also noticed that Rainier Arms has dropped the 308 BCG's attached to their name from their website but still sell the 762 brand.  I can't see that lasting much longer.  As far as "faith in your fellow Americans"....give me a break  It wouldn't be the first time people got screwed over by fellow Americans and certainly won't be the last.  I'm glad that you had a positive experience and that your BCG worked out for you but a lot of people out there got hosed

JP only makes the low mass 308 BCG but they are the best quality you can find IMO.  If they sold a full mass BCG I would buy it in a second.  The low mass is best used with the JP spring and buffer with an adjustable gas block.  Young makes a great BCG too if you can find them.  If you call them they might put you on a waiting list to get one eventually?

I have a Harris Tactical and it looks just like the 762 Industries and the Rainier ones that have been posted. I already purchased a JP to use instead.

Thanks, makes my decision a lot easier, that and the fact I already have the JP SCS, and JP adjustable gas block...  Now I just have to find the complete bcg in stock, and figure out if its better to send my barrel in to check head spacing with bolt or buy the gauges and check on my own...

Shadow Ops Weaponry has a 308 BCG as well. I dont think these come from the same mfg as the 726 Ind. But I could be wrong. Here it is.

I think ar15news.com still has a coupon code to get it cheaper. Here.

Not sure if its expired or not. I personally have no experience with it, but it is a good deal. I sprung for a LaRue BCG off the EE. Paid a pretty penny for it, but is definitely worth it to me.

ETA: Youngs is supposed to start making more carriers in January once they are caught up with the AR15 BCGs. `

I just placed an order from Shadow Ops - missed the info on the discount coupon...I hope it is up to snuff. They do have a return policy - but I won't have even 20% of the parts necessary to assemble my rifle. Their ar-15 style bolt seems to look nice at least.

I'm glad that you had a positive experience and that your BCG worked out for you but a lot of people out there got hosed.  762 Industries is already out of business after only being around for a few months.  They sprung up from nowhere and only sold 308 BCG's and now they're gone.  Shady business if you ask me.  I also think they were the reason I had my credit card number stolen and used for over $2,000 in airline ticket purchases.  I can't prove this but it was the first time I had used the card in months and then I get a fraudulent charge.  I have also noticed that Rainier Arms has dropped the 308 BCG's attached to their name from their website but still sell the 762 brand.  I can't see that lasting much longer.  As far as "faith in your fellow Americans"....give me a break  It wouldn't be the first time people got screwed over by fellow Americans and certainly won't be the last.  I'm glad that you had a positive experience and that your BCG worked out for you but a lot of people out there got hosed

Ok, 762 Industries and rebranded are no go for me.
Where do I turn to for a good 308 Bolt and Carrier assembly?


Why not? Because a few people got some bad carriers? I have one from JSE thats a 762ind and its flawless. All companies muck up things. Give them a chance instead of running away from a company that is trying its best to deliver BCGs when EVERYONE else in the industry is keeping them for built rifles. Have some faith in your fellow Americans.

Fair enough, but if they are out of business, why are these BCGs still popping up all the time? Maybe theyre still making em? I hope if they are they get their shiyt together cuz i could use another one.

Although I haven't had any issues with my 7.62 Ind. BCG, I am pissed that they (7.62 Ind.) seemed to have disappeared. If my BCG causes premature wear I will be beyond pissed. I'll probably pick up a JP carrier or standard carrier just in case.

As near as I can tell 762 Industries is not the original source of the BCG's.  I'm not sure who is sourcing them but I hope more reputable manufacturers enter into the market and begin putting out quality parts.

Finally brought it out to the range for some test firing and it did not go so well.  So, i put one round in the magazine, charged the rifle, pulled the trigger and it fired.  What did not happen is the ejection of the spent casing..  I also have the 762 industries bcg.  Not blaming the bcg, yet. .

When i pulled the charging handle back, nothing.  I could not get the bolt to to rotate.  Of course i had no tools with me, so i finished the day shooting all my 556 ammo and shot all my 1911's.

When i got it home, i pulled the bcg back using a wooden "pry bar" and came right out.   The casing had signs of extremely high extractor pull with a piece of the rim gone.  The case also had some expansion, which made it difficult to get out.  I put a dowel down and it popped right out.  

I took the bcg apart and inspected it.  No marks, no burs, nothing obviously out of the ordinary.  The cam seemed to have a little resistance, but nothing major.  The bolt face looks fine,



Of course, i did not take a pic of the casing, but it definitely was pulled on HARD as it was missing a section of the rim from the extractor.  I am so pissed at myself for not keeping the casing and taking pictures.

Because i did not have a chance to fire it again, its a small sample size.  But, just from the case showing the sign of the high extractor pressure, is there enough info to conclude overgassing or do i need to fire it a few 100 more times?

Search "maten" on gunbroker.  It's slim pickings but there are a couple high priced options.

When I first put my Maten together I tried to manually cycle a few rounds and it would do something very close to what you are saying, even though I was not firing the round. Then when I tried to fire it did the same and yours and would not extract even when attempting a mortar move.  I am running a mega 18in barrel. Only thing I could figure was the tight tolerance made it hard to extract the round after slamming it home with the BCG. I cleaned the crap out of the throat and chamber on the upper barrel with the chamber brush. Then I used 762 m80 ammo, been shooting smooth ever since with 762/308
