Colt M4A1 SOPMOD Block II Clone AR15 Build – Complete? + Full Parts List

The build is complete (for now). If you pay full retail for the parts listed (I shopped for deals, got some parts used, and had a lot of help from Brownells), plus the going rate for the parts that aren’t available for retail, you’re looking at a total just north of $4,000, not counting tax and gunsmith fees etc.

  1. I finally watched this back after uploading it. At one point in the video I misspeak and say "Magpul CRT Stock" and then correct myself with text on screen which says "Magul CTR." Yeah… That one sneaked by me. You know what I meant, right? Right? RIGHT?!
    Good.

  2. THANK GOD you didn't get the Geissele rail after the mishap. I have a non FSP version myself and its definitely the way to go. Looks great, I need to grow a pair and rattle can mine but taking a can to an ACOG plus 3k in parts makes me cry a little bit. Haha!

  3. Just found this video. Did you ever do any more work on this, or build anything else? I didn't see anything on the channel. I ask because now the 4 prong flash hider is more readily available. Also there is govt contract B5 SOPMODs available at Brownells.

  4. These videos crack me up…… I can put together an AR for 1/3 of the cost. It will even look and function the same, be just as accurate, WILL be 40% lighter, and you would NEVER know it was not "authentic"………..

    I could litterally build 3 rifles (optics/lights/furniture) for the same cost as this setup………

    The stuff people spend money on……….

  5. Clone life man . It's fun and expensive . That my friend will be worth a pretty penny in years to come . Might as well and just Clone them all . MK18 CQBR , M4 SOPMOD , M4A1 SOPMOD , M16A1 , And M16A4 . With the A4 though I do believe that's USMC and it's actually FNMI. The M16A3 is the rarest of them all . The USN was the only ones who contracted the 16a3

  6. With a Colt SOCOM Profile you need have an H2 Buffer . If not you will have Bolt Bouce . You will not notice anything in Semi but if you had a fun switch it would eventually malfunction due too bolt bouce. The TDP is for a H2 Buffer when using SOCOM profile

  7. EOTECH . I will just say that if SightMark CAN GIVE A LIFETIME WARRANTY AND COST WAY WAY LESS not to mention Primary arms unconditional lifetime warranty as well as vortex. The when EOTECH can offer a life time warranty I may consider spending way more money . It really make one wonder why no lifetime warranty ?Maybe because they don't believe in there products?
