Frequently Asked Questions

What was the primary focus of the T.REX Arms prototype rail test?

The primary focus was to test the structural integrity and initial heat dissipation of the new metal prototype rail during rapid fire. This included assessing its performance with a suppressed AR-15 platform rifle.

How did the prototype rail perform in terms of heat management?

The rail demonstrated high efficiency in heat management. After firing four magazines rapidly through a suppressed rifle, it remained cool enough to be held comfortably without gloves, indicating effective thermal transfer.

What firearm platform and ammunition were used in the test?

The test utilized an AR-15 platform rifle chambered in 5.56x45mm NATO. A suppressor was also attached to increase the thermal load on the rail during the rapid fire sequences.

What attachment system does the prototype rail feature?

The metal prototype rail features the M-LOK (Modular Lock) attachment system. This allows for versatile mounting of various accessories, such as the laser aiming device observed in the video.
