  1. Thanks. I've already looked at CMMG's videos. I was looking around on here to see how others liked the BHOA. since I've read bad reviews on it.

    Mine didn't come with the BHOA or forward assist adapter. I don't know if I really need the forward assist, but I plan on ordering the BHOA. After watching the videos of how to set it up, I think the bad reviews are probably because they didn't fit it properly to their gun.

  2. CMMG has a video animation on their channel that shows the installation and proper fit. I'll put the link in the description or just search "CMMG BHOA Fitting Instruction" and it should come right up. I love this thing! If only I could find .22 ammo!

  3. I just got a conversion kit and installed and shot it yesterday. Worked great except mine didn't come with the BHOA. I was really hoping that you would show installing that and properly fitting it.

    I noticed that on the last shot of the magazine, the bolt slams into the top of the magazine follower. Don't know how long the magazine will last if I don't install the BHOA.

  4. @multiHappyHacker I still plan on doing a follow a up on this to include shooting. If you want to see just the bolt I would suggest visting CMMGs' website, they have some good pics of their kits.

  5. @YouHogTube This is one of my earlier videos, none of my more recent videos have music. I'm not going to re-do this video because we don't have the same taste in music or you don't have the patience to get throught it.

  6. @YouHogTube I WOULD NEVER COMMENT ON SOMEONE ELSES' TASTE IN MUSIC OR ASK THEM TO CHANGE SOMETHING IN THEIR VIDEO FOR ME. I'm on here to learn and share, not disrepect others taste in music. To say "F'ing so-called" is out of line. If you can write a comment like that and then lecture me about not being interested in listening to those who view my videos, you credibilty is lost.

  7. @YouHogTube You seriously couldn't sit through that! I can't think of a genre of music that I coudn't listen to, or at least have patience enought to sit through to get to something I was interested in! Your Loss!

  8. @nightsniper101 Let me put it this way, all BHOA kits, which are Evolution kits, include FA now. They didn't used to. The S&W M&P 15-22 does completely function normal with charging handle and bolt hold open but the evolution kit is more cost effective. I didn't have to buy BUS or a primary.

  9. @nightsniper101 Not really with this upper since it does not have the forward assist. Wanted to have it though so that when I get another AR or a different upper it will be functional. Not that I'll ever have to use it. lol. I think all the Evolution kits include the forward assist? Got to have the BHOA, if it does not function the same it's not worth having.
