Quote HistoryOriginally Posted By Eruoen: Dude. Sweet. I've seen the photo of when it was deconstructed, and the trigger looked different than an SSF, so I'm assuming it was a Knight's? The safety is the Knight's Ambi too, right? Trigger on the FDNY from the pics I've seen was the old adjustable KAC F/A 2-stage match trigger. There was a discussion on the ambi selector somewhere in this thread, I believe the conclusion was that selector most often used on Mk12s was made by DPMS. No longer available. As I understand it, the Luth-AR M16 ambi-selector is identical. |

For those of you who sent their ARMS rings in to get tightened up, what does ARMS actually do to them to have them clamp tighter to the rail? I have a set of 22H NLS that are somewhat loose on my Colt upper and I want them to clamp better. |

Quote HistoryOriginally Posted By thatARMSguy: It looks interesting, definitely cheaper than the other options. waiting for a black upper and throwing it on an H&R lower could be a nice budget build for people who just want the looks and performance but without all the extra autism It would of been nice if they threw it on the H&R lowers they are making but I also understand they want their Sabre to set itself apart. I already have my autistic Mod 1 and Block 1 build. So I think I'll pick this up to scratch the itch for a Mod 0. |

So.
I've got Mk12mod0 with the original ARMS 38 sleeve mount (PEQ). I'm trying to replace it with non PEQ mount. I've managed to remove the rear "locking" piece with 0 issues. But I'm kind of baffled by the 2 front flathead screws. I've managed to loosen both and one basically spins freely, but won't come out, the other still has some resistance as if its screwed in but I've spun it probably 100 turns and it doesn't appear to be coming out further. Are these screws somehow retained? From the few pictures I've found of the ARMS mount it doesn't seem to be the case. Also does the rail slide off or just lift off? Seems like it should be the latter? |

The BCM rifles were built with Gen III PRI tubes and the ARMS #38 SPR PEQ2-3 sleeves. It should just be the side retaining screws in the back and the forward retaining screw that gets taken out. I don't own one any more but I'm pretty sure you have to slide the whole sleeve to the rear to take it off once those screws are removed.

Well jolly good, then something must have gotten proper fucked. The rear retainer came off no problem. The front two screws however can't be removed, the very front one spins freely but is still retained by "something", The "middle" one, there is still some resistance, but its not coming out. I took it to a smith to see if he could unfuck it. My best guess is that the screw "holes" on the actual rail broke off, or at least the front one. |

Quote HistoryOriginally Posted By thatARMSguy: Don't mean to butt in, but what are you planning to do with the A.R.M.S. sleeve once you get it off? Sell it or save it for another build? I have already sold it, last week. I'm not a cloner, something about the counterfeit lowers is particularly offensive to me. I was going to buy a full auto lower, but that fell threw with grandkids & such. So I fell back on my lower, a LMT Defender 2000 lower that has never seen another upper. Even have an original OPS 12th suppressor, but in the clone world, that doesn't seem to be worth much. And guess what, no muzzle strikes, I've been lucky, but better to be lucky than good or rich. |

Really digging the look of the original Ergo grip on the SPR. Starting to realize how lucky I was to find one after only looking for a year and a half.
 Now complete with an issued Vari-X III 3.5-10. Need to get a Harris bipod and A.R.M.S. adapter for shooting because the Versa-Pod is really just there to fill out the kit. Only bit left to finish the whole thing is the proper early collar. |

Took my Mk12 Mod 1 out today to test some ammo, and chrono it.
Still new to the lab radar so it didn't pick up all the rounds, but most of them. Sadly I only had enough ammo to do 5 shoot groups. So not great, but at least it does give me an idea so I can buy some more to try out then start stocking up.  Attached File Attached File Attached File Attached File Attached FileNemo 5.56 - Avg - 2996 fps Federal SMK 77gr - Avg - 3100fps Federal Gold Medal Berger 73gr - AVG - 2585fps IMI Razor Core - Avg - 2714 fps Sig Marksman 77gr OTM - 2513 Sadly I didn't get the average of the other rounds, but I will end up going back for more testing. The Federal 77gr at 3100fps definitely surprised, had a decent grouping with it too. Might have to pick some more out to try in the future. Also the last unnamed group is S&B 77gr HPBT. |

I will do the same soon but I will start with 69, 73,75 and 77 in different brands. So far I’ve had good results with freedom munitions 69 gr remanufactured (yes reman). For the price I’ve managed 1 inch groups all day even with their 77gr so just curious to see what other brands and weights will do in my rifle, does the added price worth the change. Have to also be realistic about what is really needed at different distances under 600 I shoot 69 is faster and 600 and on 77gr. Zero at 100 for the faster round 69 and adjust for 77 usually 3moa up.

I don’t have any FGMM 77gr SMK info myself, but my handloads that are in the middle of 5.56 pressures with 8208XBR are running 2560-2670fps in the DD and PRI 18” uppers I’ve run them through. The PRI Mk12 Mod 0 upper is faster than the DD, FWIW, but there ain’t no 62k PSI or less 3100fps 77gr load in an 18” AR. ETA: just checked my notes and 55gr Federal American Eagle FMJ is 3010fps with the OCM-5 on. No way you’re getting 90deg more with a factory 77gr round. |

Quote HistoryOriginally Posted By Cowbell: 3100 with 77's is impressive if that's accurate. Nice! Yeah I have no idea why it is reading so high for those. Idk if it was chronograph error, user error or a hot batch of ammo. I need to test it again this weekend. The rest of the ammo seemed to read accurately and I didn't move anything. |

I did have an issue where my LR was picking up particulate matter (think unburned/still burning powder, thick clouds of gas, etc), but that gave me 12,000fps readings LR told me to keep the unit 6" or more behind and to the side of the muzzle to stop the particulate matter tracking and it hasn't done it since. |
