The heart of our tough 2.5X Prism Scope is the ACSS 5.56 CQB-M1 reticle that combines ranging, wind leads, moving target leads, and ballistic drop compensation out to 600 yards. The outer horseshoe of the glass etched reticle is used for close quarters engagement, simply place the generous semi-circle on the target and run with it! Each side of the horseshoe also has our integrated ranging system. Place the bottom of the target on the bottom rung and range up. If you know your targets are roughly 18 inches wide, they can be ranged on the side Auto Range system, or directly on the BDC hold overs! Two dots on either side of the inner horseshoe offer a moving target lead moving with an average speed of 8.6 MPH. Each step of the BDC system includes a 5 MPH wind hold, drastically improving first hit probability at any range. As an added bonus, the glass etched reticle does not require batteries or illumination, but 11 brightness settings (including daylight bright) allow for fast acquisition in close quarters, or enhanced visibility in fading light, powered by a common CR2032 battery!
The PAC2.5X offers mounting flexibility to suit your needs. The included 1913 MIL-STD Picatinny thumbscrew mount can be removed and replaced with any mount that accepts AR-15 carry handle-type optics, or simply so you can mount the 2.5x Prism Scope directly to an AR-15 style carry handle. Optionally, shooters can add an M1913 picatinny rail to the top of the optic to piggyback a red dot back up sight. The PAC2.5X offers the perfect amount of magnification to balance close quarters speed with hits at medium range, in a flexible and durable package.

Great Optic, Great price
by Mike -
Red dot didn’t work for me, along with having an astigmatism, I found that my target was not as sharps as it could be even 20-25 yards indoors. I hoped that this 2.5X prism would be the solution to both my problems and I am completely satisfied. Reticle is sharp and the small amount of magnification is perfect. Worked fine indoors with illumination off (black) and on (red). Eye relief is decent, a bit of an adjustment coming from an unlimited eye relief open emitter dot, but perfectly acceptable. The offset mounting allows you to bring it farther back if needed and you still have room to grab the charging handle without issues. Listening to other reviews I degreased the screws and used blue Loctite (as the manual suggests). A quick note to the reviews mentioning the reticle is off-center or crooked. I believe this is an optical illusion as mine appeared tilted slightly counter clockwise while shooting right-handed, switching to left it looked tilted slightly clockwise.
Clear Glass, Great Reticle
by Justin -
The glass is plenty clear and the reticle is by far the best available. The mount is good quality but I will likely swap out for a slightly taller one as I can see my thumb in the bottom of the lens whenever I grip the handguard. I can actually see my collapsed MBUS Pro front sight as well. Not deal breakers at all, especially since these take the super abundant ACOG mount. Only complaint is eye relief. Eye relief is naturally not as good when compared to red dots but I was hoping for a little more. I have a short length of pull naturally (2nd position) but still had to mount all the way back on the receiver to get a full picture. No big deal as you can easily just mount front BUIS in front of this optic.

Unbeatable Sweet Spot
by Unbeatable Sweet Spot
Cantilever mount, stupid simple lockup, crisp AND bright (no bloom or blur on the reticle). Tried this against a Vortex 3x Spitfire Gen2. Note to self, never get a rifle optic of any kind with an objective less than 25mm. 32mm like the SLX is the sweetspot for magnification under 5x. The Spitfire costs $100 MORE if you find it on sale but its like looking through a straw where this one is like looking through a TP tube, much better eye box and relief.
Crystal clear and holds zero.
For the money you would be hard pressed to find better. Flawless on many different platforms and holds zero when swapped very well

This 2.5 prism is a solid optic. Acss work great and have taken the ar out to 500 yards with just a little effort. I own 3 of this model and 7 PA scopes overall. They are perform very well.

Awesome Red dot for the price ! Pretty durable to. It’s just as good as other that cost at least twice the price. After purchasing one I just had to get a second .
