PRIMARY ARMS:

MicroPrism now with T1 Footprint

PRIMARY ARMS has launched the SLx 1x MicroPrismT, compatible with H1/T1 mounts, featuring all existing 1x MicroPrism reticles, including the new T-Dot reticle. It maintains the compact design and usability without battery power, offering a generous eye box and includes both a tall riser and low mount for versatility.

PRIMARY ARMS has released the SLx 1x MicroPrismT, a new version of the original best-selling SLx 1x MicroPrism built around an H1/T1-compatible mounting footprint. The H1/T1 interface is the most common red dot mounting standard on the market, so the MicroPrismT works out of the box with a broad selection of popular aftermarket mounts and risers.

The MicroPrismT is available with all existing 1x MicroPrism reticles, including both ACSS Cyclops and ACSS Gemini with Red or Green illumination. Additionally, new to the lineup is the red-illuminated T-Dot, the first Red Dot Bright (RDB) reticle in a Primary Arms prism scope. The T-Dot prioritizes simplicity: a bright illuminated center dot with outlying stadia lines forming a T shape. It’s designed to get on target quickly while still offering the etched-reticle benefits of a prism, including usability without battery power and a clean image with astigmatism.

Beyond the new footprint and the T-Dot reticle, the MicroPrismT is the same optic that made the original a best-seller. It has the same compact form factor, same generous eye box, same etched reticle that works with or without illumination. Out of the box, it includes both a tall 2.26″ riser and a low mount.
