Welcome to MK Machining

Manufacturer of precision rifle chassis and accessories

Look below to see a preview of our Remington 700 bullpup chassis, scope levels, throw levers, AR500 targets and more!


We have new "modular" targets coming very soon that allow the shipping of up to 24" squares via USPS flat rate rather than the typical Fedex or UPS ground that gets very expensive for larger targets. Check out our $100 AR500 packages as well, any steel and mount purchase of $100 qualifies for a free throw lever of your choice!


The MK1 is a drop-in chassis for any Remington 700 short action rifle. The trigger linkage is self-contained within the chassis and easily installed by the consumer. A customized Timney Calvin Elite trigger is hooked into our linkage for a phenomenal bullpup trigger adjustable from approximately 6oz-2lbs. This chassis has many modular and ergonomic features, and will be available in the coming months.

To see our progress on the MK1 chassis and other MK Machining products (along with general status updates from the company), visit the Development page.


MKM has the largest selection of throw levers and innovative scope and rail mounted levels, at unbeatable prices! Universal sun shades are now available in 10mm increments. Simply slide them in place for a secure, yet quickly removable fit. No matter your preferred optics brand, we've got you covered.
