MK Machining Releases the MK2 Bullpup Chassis – SHOT Show 2019

MK Machining is the manufacturer of a one of a kind Remington 700 short action bullpup chassis that you may not have known you needed until now. The current model is the second version (MK2 Bullpup) of this idea and they have made huge improvements in aesthetics and functionality.

The MK2 Bullpup Chassis made by MK Machining is the best Rem700 bullpup conversion chassis currently on the market due to it’s lightweight, customizability and adjustability. Pictured is an available option for a forward bolt handle, bringing the bolt closer to the trigger.

Before moving on too far, it is imperative to address a question that many have. “What is a Bullpup?” Here is a simple definition: A bullpup is a firearm design where the action is pushed back behind the trigger mechanism, allowing it to become shorter and keep the same barrel length.

Here, you can see just how streamlined the MK2 Bullpup Chassis is. All extra material has been trimmed off in order to drop overall weight.

One of the reasons that the MK2 Bullpup Chassis really stands out to me is due to the focus on its design which reduces weight and increases functionality. The MK2 Bullpup Chassis is streamlined down to be as light as possible while still providing all of the structural support necessary as well as maintaining the ability to add on accessories such as clip-on nightvision, bipods and other items. The bullpup chassis looks strange compared to the conventional rifle but its ergonomics would surprise anybody. The butt plate and cheek piece have adjustments that enable the the rifle to be tailor fit for any number of shooters.

The LOP of the butt pad can be adjusted without the use of tools. The chassis accepts left and/or right handed actions and the cheek piece can be switched from right to left handed sides and can be adjusted for height and LOP.

Now for the elephant in the room: trigger quality. Bullpups are known for having less than great trigger pulls due to inherent design limitations, however, this is not a problem with the MK2 Bullpup. MK Machining has worked with Timney in order to get their own custom Calvin Elite trigger. this trigger coupled with MK Machining’s linkage system yields a zero creep, crisp trigger pull that is able to be adjusted from 6 ounces to 1.5 pounds. Yes, 6 OUNCES! I have not seen anybody yet that was unhappy with the MK1 or MK2 trigger for this reason.

the MK2 Bullpup Chassis comes with an Arca rail, M-LOK attachments and threaded 10-32 holes for whatever kinds of attachments you want to install on the forend.
