  1. Caleb, i would love to see you take us thru your box of tools and supplies for firearm assembly. All the jigs, the punches, the wrenches, the chemicals (like Aeroshell, threadlocking compounds etc…)
    Make recommendations based on the type of firearm being assembled, tips and tricks that real gunsmiths use to simplify these processes.
    Pull a Caleb on us. Look up the meaning of your name.
    Appreciate what you do and what you bring to the Brownells brand.

  2. We appreciate you Caleb for having these great you-tubers on Brownell's to build a special Rifle for themselves!!!🤗 These custom builds also shows us who has knowledge about building a Firearm from there personal experiences!! LOL 😂

  3. Almost done the exact build but radian saftey and dd upper and 11.5 barrel. Definitely need to be done with shorties. Well I’ll eventually build a 12.5 or 13.7 or.9 build. May change it up and go with a g$ mk4 or mk8 rail but man I love DD riii rails.

  4. From my understanding, you should be adding grease to both the threads on castle nut and also on the barrel nut. With the gas block screws, I'd be using Rocksett. The castle nut should be torqued to 40 ft/lbs. I also wouldn't hammer the barrel into the upper… Use a torch and heat up the upper allowing for the barrel to fully seat. The barrel nut will also fully seat the barrel.

  5. You can easily thermal fit this barrel man. Don’t hammer your barrel. Thermal fitting is easy and it will only take a minute. If this dude was experienced he would have known that Bcm uppers have a very tight fitting tolerance. Influencers are for entertainment only and you can’t really count them as experts. I think brownels is trying to expose them with these videos 😅
