INTRODUCTION:
This is a technical oriented review of the EOTech XPS 3-2. The EOTech XPS 3-2 has a BDC reticle so I will focus on explaining the reticle. I will also be doing a battery life test.

EOTech XPS 3-2 RETICLE EXPLANATION:
The EOTech XPS 3-2 reticle was calibrated with the M855 ammo with a MV of 2900 FPS with a 50 yard zero. So the center dot is calibrated for 50/200 yard zero and the second dot is for 500 yards. And as many of you EOTech owners already know, the bottom of the reticle is the holdover for 7 yards.

Generally, the 100 yard zero is the better short range zero as the space in between the two dots is dead on at 300 yards. The 50/200 yard zero is the better long range zero because the second dot is good for 500 yards and the space in between the two dots is close to 400 yards. It is best to take your load and see how they match up for you because bullet weight and velocity can change things slightly.

So with that info, I plugged it in to the JBM program and I came up with the distance/drop of the 2nd dot:

Ammo: M855.
BC: .304.
MV: 2900 FPS.
Zero Range: 50 yards.
Sight Height: 2.6".
2nd dot: -2.8 MILS/-9.7 MOA.



TRAJECTORY EXAMPLES WITH A 100 YARD ZERO:
Ammo: M193.
BC: .243.
MV: 3130 FPS. (16" barrel).
Sight Height: 2.6".
Zero Range: 100 yards.



Ammo: Hornady NATO 75 GR BTHP W/C T2. (MK262 will be nearly identical.).
BC: .355.
MV: 2700 FPS. (16" barrel).
Sight Height: 2.6".
Zero Range: 100 yards.



TRAJECTORY EXAMPLES WITH A 50/200 YARD ZERO:

Ammo: M193.
BC: .243.
MV: 3130 FPS. (16" barrel).
Sight Height: 2.6".
Zero Range: 50/200 yards.



Ammo: Hornady NATO 75 GR BTHP W/C T2. (MK262 will be nearly identical.).
BC: .355.
MV: 2700 FPS. (16" barrel).
Sight Height: 2.6".
Zero Range: 50/200 yards.



RESULTS:
I went to the 300 yard range to see how the BDC reticle matched up. From my calculations using the handloads of the Hornady 55 GR FMJ/BT with a MV of 2900 FPS, 300 yards should have been right between both dots. I did 3 10 round shot groups using the FBI man sized targets and it was dead on at 300 yards. If you have an FBI target, at 300 yards, place the center dot on the top of the paper and the lower dot on the bottom of the papaer and pull the trigger and it will strike right in the center. So for any target, just place the target right in between the two dots at 300 yards and you will be on. With the Aimpoint 3xMagnifier I had no problem seing the target at 300 yards.

BATTERY TEST:
The EOTech XPS 3-2 has a reported battery life of 600 hours on setting # 12, which is the standard setting when you turn on the EOTech. So in theory, if I turn on the EOTech XPS 3-2 everyday using the 8-hour setting, the battery should last me 75 straight days. I started the battery test on 12-18-09 and I sold the EOTech in late March, which was over 75 days, and it was still on the original battery. So, the battery life of 600 hours is pretty accurate.

CONCLUSION:
After owning the EOTech XPS 3-2 for a few months and using it, I decided to sell it. The second dot just got too annoying after a while. I really like the new XPS Series and I think EOTech has finally got it right, but if given a choice again, I would have just purchased the XPS 3-0 instead.
