I have a RRA 16" custom 9mm carbine. It's a lot of fun to shoot, but I was disappointed in the recoil and muzzle rise. (I compete in USPSA PCC and steel challenge.) It was partially my mistake in not understanding the direct blow back system. So the first thing I did was...

- Get a compensator. (It did very little, but it did do some.)
The next thing I did (to a small degree) and plan on doing is...
- Experimenting with light hand loads with a lighter buffer (RRA buffer is 5 and a half ounces) light loads with OEM buffer makes for a slow/sluggish bolt)
- Experimenting with heavy hand load with a heavy buffer (violent slam of bolt in the tube with hot loads and OEM buffer) heavy hand loads would allow me to reach out a little further in distance and not have so much bullet drop.
I also did the...
- Added quarters to the back of the buffer tube to remove bcg excessive travel. It did help.
So for my main question...
Does anyone have any real world experience or 2nd hand experience with the hydraulic buffer or aktive buffer from Blitzkrieg (https://www.blitzkriegcomponents.com...s.asp?Cat=1823)
or
the adjustable buffer system from Taacom?
(https://taccom3g.com/product/taccom-...buffer-system/)
or
should I just experiment with different buffer weights for my PCC?

* All three buffers are expensive, but if they truly make a noticeable difference than I'm willing to spend the money.

Thanks for your feedback! At the moment, I'm really leaning towards the hydraulic buffer.
