Anybody install this? Looking for opinions from those who have installed this upgrade.
I don’t think recoil is all that bad with the standard Sub 2000, but I’m curious if this heavier bolt works noticeably better in recoil as Kel-Tec claims.

The heavy bolt removes some snappiness but I did not notice a big difference in felt recoil. I do not have one but suspect the muzzle brake would make more difference.

I have one in .40 S&W, so installed the rubber tube cover and a butt pad to cushion my shoulder after more than a few rounds. The ‘recoilless’ charging handle and internal buffer pad are good adds as well.
Those made enough difference for comfort for me. I enjoy the authoritative thump, lets me know I’m launching some power! Ruger .44 mag carbine, M-1 Garand, Savage 99 in .308, 12 Ga.–I like to run with the big dogs! (you just have to roll your own to make it ‘affordable’!)

It works well in my .40 and slows everything down enough that my Sub runs much cleaner
It was a good investment.
The brake, bolt and buffer combined compliment one another on my Gen2

That’s what I was hoping to hear.

I have the brass bolt,Mcarbo Stuff, buffer pad,
heavy handle ON and ON and ON.
.
Take the time to read polishing S2K thread for additional stuff.
I found that polishing the bevel where the recoil spring goes into the recoil bolt helped. Along with that the interface between the bold and hammer can be SMOOTHED.
Ad Infinitum.

I have a .40 s2k and added a heavy bolt along with full mcarbo upgrades…
Haven’t shot it yet as it’s been sitting in my safe for over a month now…
Wouldn’t know what stock feels like

That is cool. I have a foregrip but it does not open like that. Pretty cool idea.
