The gas system is adjustable at the block

A RIFLESPEED gas control lets the rifle be tuned to the load and to a suppressor, rather than being fixed by port size at manufacture. The gas block is pinned to the barrel, in line with the Bombproof by Design™ philosophy: a pinned block cannot shift on the barrel the way one held by clamping or set screws alone can.

The selector is configured at 90°

The Radian Weapons Talon® 45/90 can run as a standard 90° selector or a 45° short throw by rotating the shaft 180° inside the lower receiver. It is installed at 90° and can be reconfigured by the end user.

The buffer retainer is reinforced

The Forward Controls Design RBF replaces the standard buffer retainer, a small part that takes repeated impact on a large-frame rifle. It is a durability choice, not an accuracy feature.

* A note on the name

SOTM5 names the rifle; the serialized part is the lower receiver. MOD-0FA names the thermal-fitted billet upper with forward assist. PRS Lite identifies the stock configuration, built with the Magpul PRS® Lite. The serial number on the left side has been blurred in this photograph; no other marking has been altered.
