I have seen both RIS II Barrel nuts with a slight hole and 7.62 Lite Barrel nuts with a slight hole. As far as the Rocksett, I have had to boil them for up to three hours before they'd come off. Anything after the three hour mark, I let the water cool off and the move the pot to a spot where it can sit for at least 24hrs. That stuff really is quite amazing. |

Just joined the MK18 club and I love it. It's the shortest AR15 barrel I have, so I was trying to find some data/research on defensive ammo ballistics testing for barrels this short, similar to Dr. Roberts's comprehensive testing.
Unfortunately, it seems like testing is relatively sparse. Most of the time it seems like people are simply picking ammunition for their 10.3" barrels with proven ballistics for 14.5-16" barrels. I'm not sure we can count on those tests for my MK18. Does anyone have any ballistics testing for barrels this short. |

View Quote This should give you a general idea of the sort of velocities you can expect with many popular rounds: https://www.ar15.com/forums/ar-15/-/16-714088/? Personally, my current defense round is Hornady Black 75gr SBR, but I'm probably going to work up a 77gr SMK load in the near future. Basically, an Mk262 clone. I'd like to have a little more defense-grade ammo on hand, and buying factory ammo at $1 per round just ain't my cup o' tea, lol. No real way to clone the Hornady Black SBR load in any case, due to the specialized powder; but the components for a decent, economical Mk262 clone are readily available. |

Thanks for the recs on ammo. I was thinking about going with the MK 262 clones. I just assumed that in an SBR, the barrier blind soft point variants would be superior (e.g., 62 grain Fusion, GD, etc.).
Isn't the reason the military uses HP's in the MK18 due to the fact that they can't use the barrier blind soft points due to the Hague Convention. I haven't researched that, so take it with a grain of salt. |

View Quote Normally I carry either Mk262 or M855A1 as my to go ammo. Mk262 is more accurate at longer ranges 200m-600m. Which I normally carry is dependent on how much on hand. M995 AP if I have a hard target. Also carry one mag fully loaded with tracers for marking targets for the heavier weapons (30 rd USGI with either red/orange tape). Only use M855 for range use as least effective. CD |

When I hit the NV button, I have to press it twice to get an optic. The optic I get is fairly bright. I've never worked with NV or have another NV optic, but its brighter than I would have guessed. Pushing the NV button will get the optic to turn off, but i cannot use the arrows to get it back on without pressing both arrows to turn it "off". Additionally, when I turn it to max brightness and turn it off, it turns back on with the mid setting. Any of this sound familiar? From what I've read, it should remember my setting. All this is leading me to think its fake. Eotechs website said a easy tell is a visible red LED. If I look at the back of the optic steep enough, it seems like I may see an LED. What do your guys' look like? https://i.imgur.com/1VkwZWu.jpg Edit: I should add, I put about 200 rds through it and everything seemed fine. Anything else I should be looking for? View Quote I have seen fakes and none of them are that well done. Compared to a real eotech they are pretty easily identifiable. You could email eotech with the serial # or call them. They will verify it. Could be Eotech just sent you a bunk optic If you feel, post some general pics of the optic. Side, front, back, etc. Should be able to tell off the bat if its fake unless there is some new secret optics factory in Shanghai pumping out 1:1 clones. |

NV settings are like SUPER dim.
Go into a dark/dim room. Power up with the square buttons. Hit the NV button. Even though it looks like it turned off hit the (+) brightness like 10X. You should see a faint reticle in the dark room. In a dark room, I can generally only see the top 2 or 3 brightness settings. |
