| Looking at a MicroMoa 11.5 barrel/block combo for a build that will get a can at some point, any one have feedback on the barrels? I was looking at BCM and DD for barrels and was looking at adj block for those, but this combo seems like a good way to go. Thanks for the input. |

I'm looking at their 14.5" barrels. What rails will they fit under? Centurian, daniel defense... Check out the link on their website it lists a few known issues. http://micromoa.com/rails-with-issues/ |

Centurian, daniel defense... Check out the link on their website it lists a few known issues. http://micromoa.com/rails-with-issues/ There are more rails that work than don't work. See various customer pics here:http://micromoa.com/pics/ Here is a barrel review from a member here: http://www.ar15.com/forums/t_3_4/660735_Building_SBR_and_need_advise.html Lot of barrels out there, hopefully some more people can chime in. Thanks for your consideration! |

Quoted: Just order the gas block. The only problem I have with them is the plate locking, all three of mine lock into position after 100 or so rounds and I need a punch and hammer to move them to another position.

The only problem I have with them is the plate locking, all three of mine lock into position after 100 or so rounds and I need a punch and hammer to move them to another position. Are you running reloads? What kind of powder? Feel free to send one of the setups back to me if you want me to check it out. I advise customers to move the plate when they are cleaning their rifle. I use Breakthrough or Firelcean on the regulator plate and that seems to work for me. Thanks!  |

Quoted:
100 rounds? You shouldn't be having that problem. I've run over a thousand without moving the plate and while it will be stiff if I don't move it after that many rounds I don't ever need a hammer and punch. Are you running reloads? What kind of powder? Feel free to send one of the setups back to me if you want me to check it out. I advise customers to move the plate when they are cleaning their rifle. I use Breakthrough or Firelcean on the regulator plate and that seems to work for me. Thanks!  http://www.youtube.com/watch?v=BEJTQ5F3-7w

All reloads using TAC and either 55 or 77gr. bullets all loaded to 5.56 specs. None of mine move like the one in the video. I'll send one in after my class next month. |

What's the new hotness in adjustable gas blocks for a 10.5" .300BLK barrel? The intention is to primarily shoot subsonic rounds with a supressor but I want the ability to run supersonic rounds as well (with or without a can) without it being overgassed and beating my parts to death.

A lot of people use our blocks for 300BLK, 6.5, 6.8, 308 etc....in addition to 223/556 of course. For a 10.5", we could do a .073/OFF/.093 for: supersonic with and without a can/OFF/subsonic That would work for FACTORY 300BLK ammo we have tested, standard power spring and up to an H2 buffer. If you reload, YMMV. You will be able to know what position the regulator is in by visually looking at it or in complete darkness by feel. Also be able to adjust with just the tip of a bullet. If none of those capabilities interest you, you can go with a set screw detent adjustable block. Let me know if you need assistance, Thanks! |

As seen in the link above, we noticed that the older factory Remington was hotter than the newer stuff and we stopped testing as that variable was changing which is beyond our control. In addition, many people that run 300BLK reload which introduces more variables. However, many of those don't mind drilling the plates out on their own to tune to their own exact configuration. All that said, that testing was just to give everyone ballpark ideas on what worked for us with the configuration outlined on that page. I know it has worked for everyone that has used that data. So to do a .073/OFF/.093 for a 10.5" 300BLK you have 2 choices 1. Order the 3 position custom with the Variant 3 regulator plate: http://micromoa.com/3-position-custom-with-variant-3-regulator-plate/ and drill it out yourself and you can fine tune it to your exact configuration. Obviously, requires work on your part and testing. 2. Order the same thing as above and select the option for us to drill it out for you for an additional $10. There is a box to enter the port sizes desired. As mentioned, I'm pretty sure it will work for you as long as you're not using some xtra power recoil spring and super heavy buffer. We used the milspec standard M4 lower configuration....standard power spring and H2 buffer. As long as you don't go heavier it will work. This is the fast, no hassle, no tuning option but most likely won't be perfectly tuned for you unless your variables were identical to ours including the same ammo used (which again changed on us). The variant 3 regulator plates are dimpled in all 3 positions. We had a Variant1 where we left the middle undrilled and the left and right pre-drilled but of course you get the few oddball customers that want OFF on the left or right so we just decided to do it like this to please everyone. The plates are pretty hard and you really need a drill press press to get the initial hole drilled after that you can easily enlarge with a hand drill.  Thanks for your consideration! |

Quoted: Amphibian, I always heard this and wondered: Does a muzzle brake really add backpressure? Anything noticeable vs a flash hider? https://www.k-var.com/shop/KR-007US.html  That really does add backpressure. I've been using them for a as long as I can remember playing with some full auto 22LR guns. Brownells adverstises the both of these as muzzle brakes: http://www.brownells.com/rifle-parts/muzzle-devices/muzzle-brakes/ak-muzzle-brake-prod5735.aspx  They both have little expansion chambers and I'd suspect that they boost the gas some also....likewise, you would think that any muzzle break that does have expansion chambers would do the same but it may be so slight that it would not be noticeable. The Bulgarian 4 piece 'muzzle brake' also creates back pressure for sure. I've got some shorty 7.62x39 builds that I've validated with them. I've been told that the ATF was going to classify them as suppressors as they are supposed to reduce the sound by some very small amount but they had already let a lot of them into the US and didn't. |
