For those of you running your 11.5 CQB suppressed most of the time, what carrier, buffer/buffer spring combos are you having luck with?

Standard M16 carrier, H3 buffer, Geissele spring. Works just fine as long as it's lubed and magazines are maintained. Sometimes the bolt doesn't lock back on magazines with worn springs when running suppressed due to high carrier velocity.  Attached File |

@AZ2A I remember a couple years ago when you were testing different options and landed on the Bootleg. What made you go back to a standard carrier and H3?

Ended up breaking the bootleg sadly. While this setup isn't the softest shooting, it's reliable and it works for me. If it's a defensive rifle I'd (personally) avoid more points of failure. Just my two pennies though

Quote HistoryOriginally Posted By Cdm1985: For those of you running your 11.5 CQB suppressed most of the time, what carrier, buffer/buffer spring combos are you having luck with? Criterion Core 11.5 inch carbine length barrel. .073 gas port. Running a BRT reduced sized gas tube. The gun will not function without the suppressor. Dead air Sandman K with E Brake, Resonator K or my Rex Silentium MG7. Running an A5 tube, Sprinco Green with an H buffer. There is zero recoil and muzzle climb with this setup and either of the three suppressors. It will cycle wolf gold and anything hotter than that with zero issues. It will not cycle wolf, steel cased ammo. With a normal gas tube, the gun would probably cycle steel cased ammo without any issues. This setup also has no gas blowback in the face, even with a higher back pressure can like the Resonator K. EDIT: Also, just to note. Originally, as the original owner had purchased it, the BRT gas tube was woefully undersized and the gun wouldn't even run 5.56 with a can on it. Shrug. I ended up drilling out the BRT gas tube to something in the .06X range (I'm sorry, I honestly dont remember what drill bit I used. Probably .068" and it runs as described above). |

I kind of assumed reliability should be good, since it's just a carrier and carriers never really break, I can always use a standard milspec bolt (c158) in the bootleg carrier, should something go wrong with the bootleg supplied bolt. |

The more I see of these the more I think I like the picatinny version over the mlok. Having to take all the accessories off of the mlok to switch barrels kinda defeats the quick change part of it all. Plus the picatinny is just sexy

     I bought a 16" New Zealand barrel with bayonet lug but didn't like the extra 2" of length when compared to my 14" MRP barrel... Then I found this gem. 14.5" carbine barrel with bayonet lug. I had it fluted to save weight and improve cooling, while also maintaining rigidity for my suppressor. And bayoneting. This is my favorite rifle, perfect in every way except for the stupid rotational QD sockets. I'll be trying to fix that today or tomorrow with some beads of epoxy. |

@slipjett,
re: MRP-H upper length If you were gonna put together an MRP-H as a run and gun 308 with lightened/dimpled SS 16” 308 barrel and a precision type rig running a 24” 6.5 barrel would you use the 15.5” or the 12.5”? Do you know the weight difference? Leaning toward the 15.5” |

Do you know the weight difference? Leaning toward the 15.5” I've been meaning to strip both uppers for a weight difference, just haven't gotten that motivated yet. Even with their caveat that 16" barrels needing extra shims to work with certain muzzle devices, I definitely would run the longer 15.5" upper with a 24" barrel as the even the shorter 20" barrels don't even look right with 12.5" upper. I'll try to motivate myself to strip both uppers and do a weigh in. Good luck. |

Appreciate the effort. I’ll be running a can and have now heard I’d need at least a 1/4” of shims to get a brake and can to fit. Not cool. I just don’t understand why they wouldn’t do 15” handguard and allow 16” barrels to work. It is a switch barrel platform after all. Not like a 1/2” shorter handguard will matter with a 24” barrel, when it definitely does matter for most popular length they sell (16”).

The chance of you finding one of those 7.62X39 barrels is probably slim to none. I would put yourself on a backorder list for a FAXON 7.62X39 barrel and wait until that comes in. D Wilson's work is fantastic. I have two criterion barrels which he converted to run in the MRP. |
