Gift Idea: AR-15 “Build Box”

I am sure I mirror many Modern Sporting Rifle enthusiasts in my zeal to maintain organization. After years of builds parts can scatter to the organizational wind. Putting together new builds was becoming frustrating, especially with the variety of MSR parts to review. Handguards, pistol grips, and other items were donned and doffed with regularity. Trying to keep track of it all was a nightmare, especially with my building location off-site from my home. One missing part, and a return trip was required.

In to potentially solve that issue is the Build Box, a rather basic product that can serve a whole lot of utility for those enthusiastic builders. In short, its a box (duh!) that features pre-cut foam designed to readily accept loose AR-15 parts to help one keep track of their parts acquisition process. The aptly named box features cut-outs specifically for:

  • Upper receiver (with optional carry handle)
  • Handguard
  • Lower Receiver
  • BCG
  • Lower Parts Kit
  • Barrel (with optional FSB)
  • Buffer
  • Misc Parts

Unfortunately, the box does not maintain a completed upper assembly – its designed for builds only.


Those interested in the box, can pick one up directly for for $18.25 including shipping to CONUS, Alaska, and Hawaii!

Yes, the box is inexpensive, but with this, its truly the thought and the fact that Build Box built the Build Box, that counts.

    Step one, put some cutouts in a box.

      Two, put your junk in that box.

      • Longhaired Redneck

        My junk?????????

      • CountryBoy

        Three, say “Ouch” when you close the lid on your junk.

    Or how about, an *actual* build box, with all the build components minus the lower receiver? Maybe even the deluxe version that includes tools and stuff? A DVD of various videos that focus on the various stages of the build? Jazz it up and offer color options, parts upgrades, etc. It’d be crazy expensive, but you know… trying to sell me a cardboard box with foam cutouts for almost $20 is already a step in that direction.

    • Martin M

      I suppose what makes it cool is that you could put this under the tree and it doesn’t scream ‘firearm’. You could hint that it might be electronics or a tool set.

      • Rick O’Shay

        Christmas at your house must have had crazy low expectations. I think if I got literally a cardboard box with cut foam on the inside, I’d be pretty freaking disappointed unwrapping that, ESPECIALLY if hints had been dropped that it might contain electronics or tools.

        • TheNotoriousIUD

          Yeah, if somebody gave me an empty box full of empty holes where gun parts should be I would be pretty disappointed.

        • Martin M

          Well, the gift giver should make some effort to fill the cutouts. Otherwise they deserve some cheap rechargeable batteries in their stocking.

          I am selling ARbuildBags for $17.25 each. They look very much like used plastic grocery bags, but they are really quite useful to newbies and experienced builders to keep their AR parts.

  • Anonymoose

    Does it fit A2 stocks or only A1s?

  • Disarmed in CA

    I used to build a lot of Revel and Monogram plastic models as a kit. An actual AR-15 would be pretty cool to buy in a “put it together yourself” package as a gift. An empty box with foam cutouts not so much. Of course there would be endless arguments of “why this or that component” from the AR master operators but I was thinking more of a “$499 beginner kit”, a $699 upgraded medium kit and maybe a $999 high-value with some extras.

      Id buy what you were saying. Especially if it came with a decent quality armorers kit.

      • Marcus D.

        You can build out a lower with nothing more than than a vice grips, a small flat screw driver and a pair of needle nose pliers. A barrel wrench is needed for torquing the barrel nut and mounting the muzzle device, and the plastic block that allows mounting to a vice is a nice extra, but that’s it.

        • PersonCommenting

          Ive gone that route before and on my last build I went to a friends house. He had all the tools plus a bolted vice with ar 15 housing for the grip housing. Took me 20 mins to put it together and a lot less swear words.

    • BeoBear

      This is exactly what I thought when I saw this. You could give someone an AR, which is awesome, but giving them an AR to build themselves, is even more awesome. I’d be beyond happy to receive one as a gift. Brilliant idea in my opinion. S

  • disqus_OTxIJaJmj0

    I actually think its kind of cool. I have a couple builds on the shelf that could use something just like this. Big fan of organization, kits, etc. Im sure the average joe is fine with that grease stained penzoil box in the garage. I have several uppers, lowers and barrels that would be nice to configure in appropriate kits. Die cut foam is always killer and its better than my current Tupperware and Midway/Brownells shipping boxes.

    • Rick O’Shay

      On second thought, I suppose I could use something like this for my kids’ “inheritance lowers.” Each box could have each kid’s name on it, and as I buy parts here and there and fill out the box, set it aside. When they graduate high school or get their eagle scout rank or whatever…. there’s a gift ready to go. But getting just the box itself? That’d be pretty freaking disappointing.

  • Wolfgar

    My nephew was given one of these. He works part time and his money is a little slow but he adds to it every month. On his birthday we knew what he needed and gave him parts as gifts which he appreciated. This is a great idea for newbies, as they learn the AR rifle inside and out they can keep their parts organized.

  • Parashooter

    It might be more useful if the upper area would contain an assembled upper.

  • Twilight sparkle

    It would be nice if the barrel was populated first, my skill with a drill press isn’t that great…

  • Mate

    Ghost or stealth gun build box?

  • Matt Huntington

    That AR15BuildBox is designed & built by a badass combat veteran / Army Ranger that knows his way around the AR15 platform. He’s a great guy & does a lot for the community.

  • Frank

    I ordered 5 kits for Christmas… It’s cleaner then coal.

  • J.E.Walker

    I believe those boxes are now illegal in Massachusetts unless they are “pre-ban”!

    • CountryBoy

      Yeah, they now require shorter cutouts for 10-round mags instead of previously allowing 20- and 30-round mags!
