Frequently Asked Questions

What are the main drawbacks of the Desert Tech MDRx?

The Desert Tech MDRx suffers from significant zero shift due to its removable handguard system, ergonomic issues like a binding magazine release, and the impracticality of its multi-caliber conversion feature which adds weight and requires re-zeroing optics.

How does the Desert Tech MDRx perform in terms of accuracy?

Accuracy testing for the MDRx yielded mixed results. In 5.56 NATO, groups ranged from 4 MOA with 62gr Norma to 1.5-2 MOA with 77gr OTM. The 20-inch .308 barrels reportedly experience 'barrel whip', making 16-inch barrels generally more accurate.

Is the Desert Tech MDRx a good 5.56 bullpup rifle?

As a 5.56 bullpup, the MDRx is generally considered less practical due to its extreme weight and past reliability concerns. However, it shows more promise as a compact .308 battle rifle where its weight is more competitive and its short length offers maneuverability advantages.

What are the ergonomic challenges with the Desert Tech MDRx?

Users may encounter a frequently binding magazine release and extremely stiff disassembly pins that often require tools. The bolt release is located behind the magazine well, which can be awkward for some shooters.
