Update M10/45 .22LR Conversion Unit

We are still filling bins with parts for the M10/45 .22LR conversion unit.  So far we have made a couple of modifications to the conversion unit that will increase reliability.  We have included a bolt “stop” above the firing pin that keeps the hardened firing pin from hitting the hardened barrel after the last round is fired and ejected.  Another modification is the use of a “booster” to increase backpressure.  Since our design is “blowback only” the increase of backpressure by using the booster increases the reliability.  Our booster is disguised as a .22LR caliber suppressor but it can be removed from the actual barrel and an actual .22LR caliber suppressor installed, as long as the threads are standard ½ x 28 TPI.

Here are a couple of videos of the unit using 100% production line parts.  The first video is burst fire – click here.  The second video is of two magazine dumps – click here .  We didn’t spend too much time with the video camera as the conversion unit was way too much fun and we all wanted trigger time! The magazines are still 20 round steel magazines (Maryland compliant) patterened after the H&K 270. We are working on 40 round steel magazines as well.

We are in the process of having the parts of the units manufactured and are still on track to have them available in time for the SAR East show.  At the moment, we have not begun work on alternative grips to accommodate conversions but now that we believe to have all of the bugs worked out of the unit, we will begin design production of the various magazine well adapters.

As for the M11 conversion unit, many of the beta testing and design changes that were incorporated into the M10 unit also will be used for the M11 units.  Now that we have the M10 unit running reliably, we are moving closer to turning our sights on the M11 unit.

  1. I am very interested in your 22lr conversion kit for the MAC 10 45. I would like to get more information on it and when it will be available.

  2. When.when,when?

  3. Waiting…

  4. I see these are from a few years back, but any chance these panned out? I’d love to have one on my M10/45.
