Earlier I reviewed Primary Arms’ MD25 red dot sight. Well, they also have a new GLx 2X Prism with ACSS CQB-M5 reticle. It is a simple, compact, lightweight 2x optic and they make a version that is set for .300blk/7.62×39. I requested it specifically to test it on two .300blk guns, my Troy Pump Action Rifle and the Pork Sword.
I really wanted the optic for my Troy PAR. It is a pump-action rifle that is very quiet when suppressed but is faster than a traditional bolt action. Plus it has most of the same operating procedures as a semi-auto AR-15.
The GLx 2X Prism is sort of like a budget version of a mini ACOG but with the added benefit of the ACSS CQB-M5 reticle.
The ACSS CQB-M5 reticle has an illuminated semi-circle with a chevron in the center and three dots below for BDC. Below that is the ranging reticle.
The reticle is set up specifically for .300blk supersonic and subsonic loads.
The left side of the GLx 2X Prism is the illumination power knob. This illuminates the horseshoe and center chevron.

Shooting The GLx 2X Prism
I tested the GLx 2X Prism with both supersonic and subsonic .300blk ammo. I used Sellier & Bellot 124gr FMJ for supersonic tests and Ammo Inc. /stelTH/ subsonic 220gr TMC for subsonic tests.
I was able to use the BDC of the ACSS CQB-M5 reticle to make hits out to 400 yards. However, with just 2x magnification it was difficult to make corrections when I missed.
For a small lightweight optic, the GLx 2X Prism gives you a little bit more practicality over a simple red dot. I think a red dot with the ACSS reticle and 3x magnifier is a little more practical, but the GLx 2X Prism is perfect for SBRs with very little rail space. I think this optic would be perfect on a SIG Sauer Rattler. The GLx 2X Prism retails for $369.99. For more information go to the Primary Arms’ website.
