What is different between the MCX and MPX that make this non-interchangable? Will this fit the MCX Hybrid/MCX AR15 conversion?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on September 22, 2022

No, the Maxim Defense Industries CQB Stock is only compatible with the MPX, and MPX K via the 1913 interface. The receiver between the MPX and MCX is different and would not allow for proper functionality of the sliding stock.

Expert Answer

Todd, guest, from MA, United States, asked on December 15, 2021

Being that my arsenal sam7k-34 has a 1913 rail on the butt end. Will this fit

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on February 08, 2022

No. The Maxim Defense Industries CQB Stock is not a direct fit to 1913 picatinny. It is proprietary to the MPX. The sliders would also interfere with your fire selector when fully collapsed.

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on February 08, 2022

No. The Maxim Defense Industries CQB Stock is designed to fit the Sig MPX only. It does not attach to a standard 1913 picatinny rail. It is proprietary to the MPX.

Coleton Hebert, member, from TX, United States, asked on September 23, 2021

will this work with the Jmac customs RSA MP5 1913 rail adapter on a PTR 9CT?

Expert Answer
A
Answered by Tom B, Gear Expert, from IL, United States, on October 29, 2021

It appears that this would be compatible with your setup. The only possible issue would be the distance between the rods, but they should be low enough to be out of the way. Also the blending with the lines of your adapter, as this is designed to match the MPX.

Riccardo, guest, from Lombardia, Italy, asked on July 02, 2020

May I ask if this stock works on MCX, 9 inch barrel/300AAC caliber? I am speaking about the gen 2 (M-Lok forehand). Thank you. Riccardo Castiglioni

A
Answered by DangerMouse, member, from NC, United States, on March 11, 2021

Late reply, but no. The MCS has a forward assist which blocks the right side from collapsing. I mean, it would fit, but it wouldn't collapse.
