Damn, THAT didn't take long for you to find!!!

Just got off the phone with Leapers/UTG. Asked the question - they only make ONE carbine receiver extension, just like I suspected. All these companies that say this is for "AR-10" are incorrect, because it certainly won't fit AR-10 Carbine recoil parts, and function. Will not. It will work with DPMS-based LR-308-type recoil parts, and that's the weird spring that nobody can get right, besides Sprinco and Wolff, and the 2.500" shorty 308 buffers. Talked to the LE/MIL rep there about this very thing. They make ONE carbine receiver extension, and it's for the AR15-specs. Now, here's a pic of a bolt "locked back" on an empty MagPul LR-20 P-Mag, in an Aero Precision M5 upper and lower. It's a D Wilson 308 BCG. Receiver extension is DSG Arms mil-spec AR15 receiver extension. Buffer spring is a polished DPMS LR-308 buffer spring. Buffer is a regular AR15 Carbine buffer (3.0 oz, 3.250" long). At first, it wanted to catch, but would slip off, and the empty mag is what's forcing the bolt catch up. It wouldn't stay, on it's own. If I manually hold that bolt stop in, and ease the BCG there, the bolt stop catches the BCG body, and it's nowhere near close enough to catch the face of the bolt. That receiver extension has an internal depth of 7.000". So, OP, please confirm the internal depth of your receiver extension, buffer and spring removed. A tape measure is more then sufficient for a close-enough reading. Just insert until it bottoms, and make the reading at the top of the receiver extension where it meets the lower receiver. It's 7.000", and it'snot7 5/8", which is what you need to run the Armalite AR-10 Carbine Recoil System. The guy at UTG hooked me up with a permanent 25% of mil discount, too.

Nope, I figured it out - that bolt catch is only grabbing the BCG body, and not the bolt face. It doesn't travel rearward enough to catch on the bolt face, and it's probably barely catching that body of the BCG. I'm putting that combination together right now, to try out.

I have that same question myself.

Are you serious, brother?! That's Karma, right there. I put the info up on mine, here, and he proceeded to tell me how I did it all wrong, how his was just as strong as mine, yada yada yada. That's when I told him to pound sand...

Gonna be hard to make a 3.8oz H1 buffer combination, two steels weights and one tungsten, with anything but an aluminum buffer body, brother. If it was anything but aluminum, it would be heavier than 3.8oz. Look at my aluminum buffer body (2.5" buffer body) weight of 0.65oz. Your 3.25" buffer body weighs in at 0.8oz. How is that anything other than aluminum? If you messed around and invented the "aluminum magnet," I"m gonna be pis$ed. I've been trying to do that for YEARS!...

The photo above is perfect. Right in the middle of the cam pin cutout, just like it should be. It's either gonna be that, or it's 3/16" too short. I looked all over Leapers UTG website, and they don't have a specific .308AR receiver extension. I could only find one receiver extension from them, and it's for the AR15. That's not gonna be the right receiver extension for using the Armalite AR-10 carbine recoil components... These are the two best sources of info on it that I could find: https://www.thefirearmblog.com/blog/2015/03/16/leapers-introduces-6-position-308-ar-receiver-extension/ In this one, straight from Leapers, when you look at all the "related items" in that long list, there is no 308-specific receiver extension... https://leapers.com/index.php?act=prod_detail&status=utg&itemno=TLU001D I'd bet that you have a receiver extension that is 7" internal depth, right there. Perfect for an AR15, or a DPMS-based LR-308-type recoil system.

Food coma again. Just got up, seriously. Knocked me the fuk out! Damn, that was good! I was lucky enough to go out to the grill and have this greet me - what the hell? Yeah, sucked to grab the handle and pull that monster over into the shade... BS... So, on the thicker beef cuts I do, they ONLY get the salt treatment. No other seasonings. Nothing else. On thicker pork cuts, I like to toss a little of this, only on one side... Thank you, Mr. Mark LaRue. Just this much, nothing more... WooHoo!!! I do the thick pork cuts just like thick beef cuts - 7 mins per side, at about 425 on the grill... They all came off, to rest... Fired up another plate with the mashed potatoes and gravy (bulk cook a couple days ago), and corn... This is what knocked my as$ out a few hours ago. Damn, that was good...

Is this a completely different build than the one gun described 3 months ago?... I'm just trying to figure shiit out here... Aaaaaaah, Floydie. Master Gunsmith of Everything... I miss that guy...

I was waiting for that... Wait, I wonder how long he had to WAIT for that?...

These 3 pork tenderloin cuts are KILLIN' ME!... They're in the "salt treatment" right now, just like steaks, to soften them up and break down the tissues. I can't wait to get these thick bastards on the grill... Couldn't pass them up at 1.77 a pound...

How far should what go? The gas tube? Just get the pic. It should go to the very center of the cam pin cutout. If you're talking about the tape measure, into the receiver extension, it should go 7 5/8" into the receiver extension, measured at the top part of the receiver extension.

^^^ THat looks like the grip on a Daisy 880 bb gun, that I cut the stock off of as a kid!... I cut the barrel off, too, just after the handguard...

Hit this one, if you will, please - just saw your post. It's easy, just do it now, and no need tocall them for anything, man. Also, if you can, get a pic up of how far that gas tube protrudes into the upper receiver - need to see the relation of how long it is, and how far it goes into the cam pin cutout in the upper... That's an important factor...

Man, you're gonna have to stick a tape measure down this thing to show me - I've searched high and low, and I can't find any reference to the internal length of this receiver extension. I just can't. There are several sites saying that it's for the "AR-10" but we know how that is. Gotta stick that tape measure in it and put the pic up... I'm just sayin'...

You measured that to verify, yes? It's really 7 5/8" internal depth? I guess if you can lock it back by hand, then it is, 'cause that wouldn't happen on a 7" extension. Gas and lube, then. Shoot it more - needs more than 25 rounds, and needs lube. Got a build thread on this beast somewhere, listing the build details? Upper, lower, barrel, etc., by brand?

THAT is the issue, man. Right there. Measure the internal depth, and you'll see it's 7.000". You need a tube that 7 5/8" with that recoil system. Armalite AR-10 Carbine Receiver Extension, or VLTOR A5 Receiver extension. Nothing else will be right. Can you even lock that bolt back?

" I had the bolt carrier, (D. Wilson Mfg) and the buffer/spring (Armalite) permanently dry lubed with slipstream, and put wet slipstream on top of that. " What receiver extension? Armalite parts for buffer/spring are the H3 buffer and the EA1095 spring?

#1. Run it WET, if it isn't. #2. Way low round count, might need to shoot more to seal the gas system (gas block to gas tube, gas bloc to barrel). #3. Wide Open that gas block, right away. Always. Run it wide open, and cut it back from there, no matter what the manufacturer told you. #4. Highly doubt it's a mag issue, or a LPK issue, based on the reputation of both those manufacturers. Lube, and wide open gas block - gotta start there.

I kept thinking that my "lightweight" gun was 5.2lbs, but it was 5.39lbs. I forgot that I changed a few parts after that initial weighing. I added a BADASS safety and PRI combat latch to the charging handle. I think I changed that again (the charging handle) because I found something lighter. I'd have to dig it out to make sure. I built it as stout as I could, as light as I could, and the priority went to "Stout" over "Light." Had a hell of a time finding the details on it, because I didn't post it in my own thread - I hijacked JJ109s thread... @suzukiray 5.39lbs. Build parts: Yes, finished out at 5.39lbs total. Now, I told you that was a temporary buttstock system, in that pic, just so I could shoot it. The 5.2lbs was before adding the PRI Combat Latch and BAD-ASS ambi safety. After re-weighing, it's at 5.39lbs right now... Complete parts list: Upper: XProducts forged upper receiver Lower: Aero Precision forged lower receiver BAD-ASS ambi safety, long fat and short fat levers. DSG Arms enhanced magazine catch. ALG ACT trigger Battle Arms Development Sabertube / BAD-LBS buttstock system MagPul MOE K grip and poly trigger guard Standard charging handle with PRI Combat Latch Ares Armor Reduced Friction BCG complete ALG EMR-V1 10" rail with it's own barrel nut Faxon 16" pencil barrel with Faxon lightweight gasblock. Spike's Shorty DynaComp Fortis T1 mount Primary Arms mini red dot Standard parts: regular carbine buffer, buffer spring, magazine release pivot and takedown pins, ejection port door, midlength gastube and forward assist. Armalite springs throughout the lower. Don't think I forgot anything... THIS is what weighs 5.39lbs, total: JJs hijacked thread, with the details... Ray, you get into that thread, and you can see where I was telling you that I drilled out the shell deflector, to save whatever weight it saved. I didn't weigh that before and after, so I have no idea what it took off. The original intent was to keep cutting those drill holes out, and take out as much as I could, but I never did it. Figure I've got the time now, work what it is, so I might dig it out and keep going...

I think that's his pic, brother! Same weakass stock system, no sights at all... Called it a complete gun, with no way to aim it!...

Man, if I could get so lucky... I wish I was Larry, and just won everything that I entered in... He'll find that comment someday... ^^^ It's true !! A guy from Pennsylvania that bought some LaRue MBT triggers the week of July 4th won the first UU upper MBT drawing !! It's an 18" 5.56. Pennsylvania guys, go check your LaRue email !! For the rest of you, every week between now and Christmas someone that bought an MBT during the week we're drawing for, will win themselves an Ultimate Upper kit. Our MBT triggers are taking the trigger market by storm ... we expect to have made and shipped our 50,000th MBT before this coming Christmas. Order an MBT today to get in on this week's drawing. Enjoy the clean break, Mark LaRue

I didn't even think about it - never grabbed the length of the weights in the buffers. Just popped that AP shorty back apart to measure one of the steel weights I stuck back in it - 0.607" long, both of them. Just call it 0.600" for planning purposes... Found some 1/2" tungsten rod on A-zon. Prices vary WILDLY! Wow! Some people are really proud of their tungsten rod... The best deal (I think) that I saw was a 1/2" diameter pure tungsten rod, 12" in length, for $128.80, with free shipping. There's a 36" piece of it up for $505! What?!... There's C2 Tungsten Carbide on there, Copper Tungsten, etc. Just watch what you find there, and in any general search for it. Look for "pure tungsten" or something that says the percentage; saw several listings that said "99.95% pure tungsten..." So, that 12" piece for $128.80. 12/0.6= 20 pieces of tungsten, out of that 12" rod. You won't get that,because of kerf, so throw one piece out, right away - call it 19 pieces of tungsten from that 12" rod. $128.80/19= $6.78, each piece. That's not bad, right there. You can afford to build your own heavier buffers that way, if you want to brave cutting the tungsten. Shiit is harder than woodpecker lips.

That decision looks like it actually takes a step further than Heller!
