I have a 12.5" 32K. Probably my favorite gun. An OSS suppressor pretty much lives on the end of it. A different locking piece isn't needed w/ those. I tried one of my SDN6s once (before I got the OSS) for just a few rounds and it REALLY increases recoil. For sure would dent the receiver from the rollers if you did that much.

Sandman2's post has the data you need to get rolling if using a typical suppressor. The issue is if you need some locking piece that doesn't really exist. There are only so many available. FWIW, It going to be easier to turn down a 12.5" 32K than a 16" 32 as it will already have less gas/pressure.

They have been out of stock for MONTHS everywhere. Atlantic just got them back so they are still in production. If you want one of the K's buy it soon.

WIth any HK, If you use a baffle based suppressor you'll probably want to try the next step lower angle locking piece when shooting suppressed. IIRC, the stock 32K locking piece is 70 deg (but don't quote me on that) so a 65 or 60deg should do it.

Should be a blast w/ a binary trigger. They are very soft shooting.
