What BCG do you run? Why no lube? Quote HistoryQuoted:
Quoted:
Yeah! Great trip, I was really surprised that it ran as well as it did under the conditions, and I'm pretty sure it would have run 100% if I'd ever lubed it. The bolt is so gritty that moving the bolt back and forth in the carrier is like fingernails on a chalkboard. What BCG do you run? Why no lube? It's from Shadow Ops, not sure who made it. They have closed their doors I believe. No lube because I was doing a lot of shooting and freezing my ass off, and I forgot to maintain the rifle. Stupid mistake, but it only effected a couple of shots. I was surprised when I got home how dry and gritty the bolt was. |

They have 2 versions of the A-peg grip: "Initially designed with the precision shooter in mind, the folks at LaRue Tactical queried trusted individuals in the precision shooting community what they would prefer in a grip. The result is the LaRue A-PEG™. The project grew into an accessory that featured ambidextrous geometry that can be used by all shooters, enchaining control of AR15-type weapons. The A-PEG™ is available in two sizes; Regular (for 5.56 receivers) and Extended (for 7.62 receivers). The Extended version fills the “gap” in AR10-platform receivers. Inspired by the human hand, the unique “flats” on the front and back fall more naturally onto the geometry of the hand’s structure. The flat front also provides indexing to help level and square the firearm to the target. A sculptured palm swell on either side fits nicely into the hollows of the palm. A gentle taper helps seat the hand towards the firearm, and helps to keep the hand from sliding. The generous texture added to the sides gives just the right amount of traction in slippery conditions. Having an A2 footprint, the A-PEG™ will attach to almost any firearm that has an AR15-type grip interface. Comes complete with mounting hardware." |

Got mine out to the range yesterday.
One (major? minor?) issue. The bolt will not lock back when I pull back the charging handle. It locks back with an empty mag though (if the round actually went off--that's a whole other can of horsefuckery described below). I removed the upper, pulled the BCG (AIM Nitride) and pushed it into the buffer tube as far as it would go.....no dice. The bolt was forward farther than the bolt catch. Stock is an Ergo F93 Pro, buffer/spring combo is an Enidine carbine 308 setup. No marks on the lower to signify the carrier is making unwanted contact. Wondering if maybe I need to swap to an A5 tube and different spring.... As for the ammo.... HSM is shit. Serious shit. I can't begin to describe how fucking frustrating it was. This was SIX ROUNDS from a box of TWENTY. as in a THIRTY PERCENT FAILURE RATE. 
IMG_1541 by Armed Ferret, on Flickr 
IMG_1543 by Armed Ferret, on Flickr Absolutely ridiculous. At least I have a 30-cal collet for my pulling die, so I can pull down the rest of the rounds, reprime with primers that actually work, and reassemble. FFS.....nothing more satisfying than trying to sight in/break in a new rifle and nearly half the fucking rounds you try and send downrange don't ignite. In fairness, the ONE lighter-colored round is a fairly light strike. The rest DAMN well should have gone off. I already emailed these photos to them, but I'm not expecting much. Like I said, I can always pull down, remove powder, deprime, reprime, recharge, then reseat. Bit of a hassle, but i'm already going to be loading for this gun, so i suppose it could be worse. Of course I'm extremely grateful it didn't go the other way, overpressure or other kaboom, and delete half my face. But yeah.....those who were at the range with me will attest I was beyond pissed.

When you pull those rounds apart I'd be curious how consistent the powder charges are. I haven't bought HSM for probably two decades because they were so bad, a really hot round then one so light you wondered if it was a squib.
Re: bolt lock, do you mean it won't lock back even if you press the bottom of the bolt release? Or are you trying to lock it back without a mag and without pressing the bolt release? |

Holding bottom of release or with an empty mag. BCG doesn't go back far enough; bolt is about 1/2" too far forward. But shooting it locks back fine. Stooxie, i appreciate the link; however, it doesn't mention the enidine, only dpms part numbers. Thanks though. |

Stooxie, i appreciate the link; however, it doesn't mention the enidine, only dpms part numbers. Thanks though. Just doing some Googling... so you've got his hydraulic buffer with a length of 3.25". The DPMS 308 carbine buffer is 2.5". There's your gap right there. My guess is that it's hard enough to make that plunger move that it's difficult to do by hand with the charging handle. Firing, through, there's enough energy to make it happen. (Answered too quickly) You might want to consider going with just a plain jane buffer until you get it running smoothly. Drop in a DPMS 308 carbine buffer and spring and try again. -Stooxie |

I don't know where you got that information, but at rest, the buffer is 2.75" and compressed it's 2.5"....same as the DPMS. So changing to the DPMS buffer and spring will not yield any length difference. It's also very easy to compress, i can do it between my thumb and forefinger. Something else is causing an issue; I'll post back with any info enidine can give me when i call later today. It could be the buffer's compression AND the spring working together though; that would make sense. I think we're both on the right track. On a side note, HSM apparently knew there were issues with those primers and never issued any sort of recall or anything. They just figured if people used it in machine guns they'd be fine, otherwise, oh well.  Quality Control....they has it.

no worries. i think it's the combination of spring and buffer compression. but it also feels like it just won't go back *ANY* further no matter how firmly i tug on the charging handle. i dunno. i'll call 'em and see what they say.
ETA: On an unrelated note, with or without BCG, my dust cover won't stay closed. It's the OEM one that came on the upper (MKM extended) from Mega. Of note, this receiver also didn't include the set screw that keeps the dust cover pin in place. Mega corrected that quickly and couldn't have been better to deal with, for sure, but it's very annoying to have a dust cover that....doesn't keep the dust out. I think a future build will utilize something a bit less expensive. Fitment issues with a $250 receiver set are much less of a disappointment than they are from an $800 receiver set. |

You were using a Rainier barrel correct? Yep, 16" Rainier match. sadly, i couldn't really get a feel for accuracy because the ammo wouldn't light. 2 rounds would go off, third would be a dud, fourth would go off, fifth a dud. random crap like that. FWIW, it was awesome yet unbelievably frustrating to see a gorgeous single-hole clover leaf developing....then the resoundingly loud click that sucks SOO HARD.
Silver linings and all that, I wasn't flinching or anticipating recoil; the crosshairs never moved on those dry rounds. 
I'm getting some rounds loaded up today; not sure when the next range day will be (hopefully before thursday; heading to Gettysburg that day with the missus for a nice day out) but this rifle and the mk12 are the top choices to take. probably won't be shooting the blackout much until i get magnification on it. |

Clamp it between 2 pieces of wood or something so you don't mar the finish on it and don't over tighten the vise and deform the gas block. With it secured in the vise and with some force on the gas tube it should go right in. |

stop PM'ing me about this thread. headspace was fine. ever-so-snug on a go gauge. this is the one that the bolt won't lock back by hand on, and i was able to get SOME HSM shit-grade ammo fired through it (most wouldn't light though; HSM admitted fault and that was basically the end of that--no offer to replace it or anything. fuck you, HSM.) and it would lock back on the last round....but pulling it back with the charging handle was no dice.
MATEN extended MKM, rainier match 16" barrel, AIM nitride BCG, ALG ACT, Ergo F93, SS10x in ADM mount because Mark Larue is a cunt. i'm done with large-frames period. please stop PM'ing me to come back here and answer questions. thanks. |

I bet the issue was the AIM bcg. But we'll never know now. either that, or the buffer setup. Really not many things it could be. Quote HistoryQuoted:

SS10x in ADM mount because Mark Larue is a cunt. There's your problem, you weren't using a Bobro.

Quick range report here for a newly built MEGA Maten-- happy to say it was boringly reliable. Shot three kinds of ammo, PPU white box 308, Federal XM80 and AE 308 red box. All 145 to 150 gr.
The only time it didn't cycle perfectly was when I was tuning the adjustable gas block to the point of failure. I backed it off two clicks and it fed, fired and ejected everything. PPU and AE casings landed at 4 o'clock, about 15 feet away. Fed XM80 must have been a bit hotter, cases landed about 2 o'clock. Leaving well enough alone. Primers all look fine, no signs of over pressure at all. Brass looks good, no dents or signs of violent extraction. All seems well. The build list is pretty basic: MEGA Maten MKM rifle length upper receiver MEGA lower MEGA 18" barrel Spike's melonite gas tube Syrac Org Gen II clamp-on gas block RCA 308+ BCG DPMS carbine buffer and spring Milspec 7075 buffer tube SSA-E trigger Magpul mags Very happy with it! -Stooxie |

stop PM'ing me about this thread. headspace was fine. ever-so-snug on a go gauge. this is the one that the bolt won't lock back by hand on, and i was able to get SOME HSM shit-grade ammo fired through it (most wouldn't light though; HSM admitted fault and that was basically the end of that--no offer to replace it or anything. fuck you, HSM.) and it would lock back on the last round....but pulling it back with the charging handle was no dice. MATEN extended MKM, rainier match 16" barrel, AIM nitride BCG, ALG ACT, Ergo F93, SS10x in ADM mount because Mark Larue is a cunt. i'm done with large-frames period. please stop PM'ing me to come back here and answer questions. thanks. Seems kinda drastic... This is simply proof that putting one of these together takes a lot of thinking, checking and experimenting. And patience. Lots of problem solving skills and patience. It's like running a custom or semi custom 1911 in a lot of ways. But throwing a fit and selling on the EE will likely work out well for someone! |

Let's see pics. I'm build will be the same as yours. Curious to see how a 18" barrel looks in that upper. |

Here's a pic:  I am builing a 7mm-08 version with almost the same config. Will be a Megalithic upper, 16" BHW barrel and set screw Syrac Gen 2 gas block. -Stooxie |

New as a user but not new to the site... This thread itself has been my go to over the last 10months...
A little back ground... Never owned an AR and just bought one on a whim, a DPMS Gen II about a yr ago...I was instantly in love with the platform... Most of my shooting background is with custom rifles and competitor archery in the past... That being said I felt like there had to something out there that was of better quality... Thus the build began... It's been more of a behind the scenes project buying this and that here and there... But I recently sold the 308 and bought a DD M7... And began shooting more and more, now my project has become my obsession... My parts list: Mega Reciever set MagPul PRS Jp LMOS Jp Silent Capture spring Troy Ambi mag release with Seekins button Seekins Tactical bolt Release Geissele SAA-E Ergo grip BAD ASS CASS-SA 26" Kreiger 6.5 Creedmoor Bull threaded by Ross Schuler SLR Sentry 9 Melonite .936 clamp on The only peice of the puzzle missing is the handguard... This is where I need help... I know I want a 15" er, to cover up the GB but can't for the life of me find one with a large enough ID to fit an adjustable .936 under... From my research, Google experts I found that I need somewhere in the range of a 1.875 ID to be safe.... I've personal contacted JP, JD, and even Unique for a custom but as far have only found one that will work ... AP customs handguards have a 1.93 ID... Are there any others that are possibly off the grid that I might look into... Thanx in advance Shad |

I think Lancers carbon fiber handguard will clear an SLR 9.

The 936 SLR Sentry will fit under their hands guards. And they have some 15, and i think a16" as well for the 308. Very nice stuff, and matches the MaTen very clean.
