Bushmaster took too long.

I bought a 10.5" 300BLK barrel and did a lot of work to the gas block, op-rod, and charging handle carriage.

It works great! Video to follow. It locked back about 75% of the time, I need to open the gas port slightly and test some supersonic rounds.

"U" Setting

Sorry for the poor video quality, I will get some better ones later. I was rushed today.

That is amazing, good work. Is this a possible future product from Unity Tactical? If so count me in, I have always liked the ACR but have converted to 300 Blackout as my round of choice. This would be a great product because it seems Bushy can't figure out when they will be releasing caliber conversions for the ACR.

What kind of mods were required? Do you mind posting some additional info?

I bought an ACR nearly two years ago with the sole purpose of using it as a 300BLK. I really doubt we'll see anything from Bushmaster or Remington, especially now with the whole enterprise up for sale.

It was fairly extensive. But it works great with subs and supers.

It may be something we look at in the future.

@goteron - have you reached out to Marvin Pitts? He's done a lot of ACR mods and is working on a 300BLK. He also produces a lot of custom parts for the ACR mods including his own custom gas system (which is a lot like the ACR but in many ways better).

It could be the start of a good joint venture. There's a lot of interest in 300BLK in the ACR community.
