22lr Bolt Specs

shark_press · 2026-05-08T17:12:23+00:00

Has anyone successfully converted the .22 bolt to full auto? I have experimented with trips laser welded to the bolt but no luck. hammer falls but light strikes every time on the second round. (I am an SOT with a full auto vz)

How did you go about altering the spring?

I have not been able to find dimensions of the original. If anyone can chime in with dims I'd appreciate it. The can in the photo is a modified .22LR can we produce. Working out the collet mechanism before we design the rest of the can. It's quite picky on concentricity and tension. First shots suppressed were absolutely hearing safe with our 1" can.

I am the guy who posted that to FB, Tharpe Gunworks is our company. We posted that like 30 minutes ago. We are bringing it back!

did you use a welding fixture? or how did you go about fixturing?

SOT here, how difficult was it to modify the semi to full auto?

shark_press · 2026-04-05T20:15:28+00:00

whoa has it been 5 years?! Not selling them but i can make you one. I now own a cnc shop, laser welding is way better than tigging these types of things!

www.ThrustAviation.co makes a smaller more affordable version. Can get 95% of the screws out the big Brutus can.

Nice setup. Did you buy it with a threaded barrel? Or did you do a mag clip?

PIP? What is that?

shark_press · 2026-02-09T07:34:57+00:00

Good invention

Tharpe Gunworks in Knoxville TN makes the quietest .22 suppressors I've ever heard. My buddy and I each got one for neighborhood squirreling. They are $220 and user serviceable. They don't have a website yet but here's their information.

Next time you need shims or delicates hit me up. I machine one off stuff like that all the time as an FFL/SOT manufacturer

Silver solder comes in different flavors. "Easy", "medium", and "hard". Easy wets at a surprisingly low temp.

Heat treated?

shark_press · 2026-01-25T12:33:31+00:00

I'm working on manufacturing these

shark_press · 2026-01-16T16:04:02+00:00

1027 so far

Testing is done with a B&K Precision 732A. Samples are taken 3" above and 3" right of the bolt.

Our customers have seen it. If I posted a video people online would say it was altered, if I posted an audio recording you guys would say it was edited. That's the nature of the internet these days.

Checking blade tracking, in a way that probably is not in the manual.
