As an FYI, ShootingSight should be releasing a tool steel hammer for the M4 in a couple of months. If you are interested, please email [email protected], and we will get in touch as soon as they are available.
These will be CNC machined Rolled Plate S7 Tool Steel, so the highest grade you can get. Price TBD - under $100. It will be 100% US made, so 922R compliant.

I kinda went hogwild after the weekend and ordered samples of all of them. Interested in some of the others also just to get 4-shell variants. Instructor recommended Vang-Comp and Ess-tac. Guess I'll be doing a heavy comparison of my own of those, and the SOE.
Mine is ordered so I haven't seen it; but from the above, and the advice of an instructor who I think ran it - the $80 mounting plate is Remington; but the $20 shell-holding part is straight Velcro. I believe you buy 2" 4' velcro strips off of Amazon to stick to the gun, and you velcro the Vang $20 part on.
It appears that brownells still has them in stock...
