The Desert Tech MDRx is critically reviewed, highlighting its ambitious multi-caliber conversion system which, despite mechanical execution, adds complexity and weight. While it struggles as a 5.56 bullpup due to excessive weight and past reliability issues, it shows potential as a compact .308 battle rifle. Key flaws include significant zero shift from the handguard mounting and ergonomic issues like a binding magazine release.

Frequently Asked Questions

What are the main criticisms of the Desert Tech MDRx?

Key criticisms include significant zero shift caused by the handguard mounting system, ergonomic issues like a binding magazine release, and excessive weight, particularly in 5.56 configurations. The multi-caliber conversion is also seen as adding complexity without sufficient benefit for most users.

How does the MDRx perform in terms of accuracy?

Accuracy results are mixed. The rifle achieved around 4 MOA with 62gr Norma and slightly better with 55gr Winchester. With 77gr OTM, accuracy improved to 1.5-2 MOA. The 20-inch .308 barrels are noted to suffer from 'barrel whip'.

Is the Desert Tech MDRx considered a good bullpup rifle?

As a 5.56 bullpup, it's generally considered a failure due to its extreme weight and past reliability issues. However, it shows more promise as a compact .308 battle rifle where its weight is more comparable to peers and its short length offers maneuverability advantages.

What are the ergonomic challenges with the MDRx?

Users may find the magazine release frequently binds. Disassembly pins are noted as being extremely stiff, often requiring tools. The non-reciprocating charging handle is HK-style, and the bolt release is behind the magazine well, which can be awkward.
