  1. I'm having a hell of time with my build that is almost identical to yours except mine is using a Wilson Combat barrel kit. I cannot get the Wilson Combat adjustable gas block to fit under two different handguards I have tried. Just curious if you had any issues with interference with yours? I've reached out to Wilson Combat for assistance. I wish they would spell out the height needed to what handguards work.

  2. Hey, Love the video. I'm interested in building a 458. FYI, I'm also a WA resident, on the Peninsula.
    I have two questions: 1) where can I obtain an A.P. upper made for the 458, there is nothing listed on their website. 2) I recently returned to WA and was under the impression that the profile bolt carrier you mentioned was prohibited. Please tell me I'm mistaken, as I would like to get mine out of storage from out of state. Thanks, keep up the rockin' and shootin'! OH!, (bonus question!) have you encountered the 375 Socom, and do you have an opinion?

  3. This is neat you guys are into the 458 SOCOM.  I'm in the middle of building a couple myself.  Once you put the adjustable Gas Block on, did you go back to a regular carbine buffer?  Look forward to more videos on this.  Thanks guys!

  4. I follow you guys on Facebook and only get updates seldomly. I have to check your page regularly to get updates. This is their way of making you pay to promote. Regardless I am a fan. At least I can stay up to the minute on YT.
