Will this be good for an fn p90?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on September 19, 2022

The Primary Arms GLX 2X Prism with ACSS CQB-M5 was specifically calibrated for 5.56/.308/5.45x39. It will work on your P90 but wouldn't be calibrated for your caliber.

Is this optic works on 8 inches AR pistol in 7.62x39?

Manufacturer Answer

Answered by Primary Arms Optics, Manufacturer from TX, United States, on June 29, 2022

Yes, this optic would pair well with your request. The scope's size proportionally fits well and is offered with a reticle measured to compensate for the bullet drop of the 7.62x39 ballistics pattern.

If the reticle is etched, how it can suit to several calibers, which have different ballistic trajectory?

Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on June 08, 2022

The Primary Arms GLX 2X Prism with ACSS CQB-M5 BDC reticle can be used with different calibers based on the distance you zero your optic given the cartridge you are shooting. The BDC reticle is not going to be exact but will give an estimation for your holdover at given distances with your cartridge. Please email us at techsales@opticsplanet.com for more information.

What barrel length is the 5.56 reticle meant for?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on March 18, 2022

The Primary Arms GLX 2X Prism will include an owners manual that illustrates different hold and ranging positions based off ammo type and barrel length. So it is basically designed for multiple calibers and barrel lengths, however, your hold will vary from different ammo types and rifles.
