Crab's Review of Pantheon Arms Prometheus Take-Down Kit w/Handguard For AR-15

We used this for a custom AR pistol build in 9mm in conjunction to a side-folder stock assembly to create a discrete carry platform which fit into a small unassuming messenger bag. The lockup is tight and accuracy should suffice for a short barreled platform.

A couple of notable discrepancies...the handguard threads are not cut such that when tightened onto the QD nut that the rails align at the 12 o'clock position. The handguard must be backed off a bit (which creates some lateral movement) and then anchored using the 3 hex screws at the lower end of the handguard. This did seem to be relatively rigid but it was questionable as if the flange was going to take the tightening of the screws without cracking. In the end, all ended up snug...I'd just prefer a better clocking of the threads or at least some sort of jam nut, I'm not sold on the clamping approach of the hex screws.

Next, there is absolutely no reason that they cannot supply a spanner tool for tightening the barrel nut. No one is going to readily have this special thin-wall socket/spanner which leaves one to attempting to tighten the nut by tapping the nut castellations with a drift & hammer. Certainly not the best method for appropriately torquing a barrel nut.
Pros:
  • Creates a much smaller storage package
Cons:
  • No socket for barrel nut
Would Recommend: Yes
