Hey guys,

I currently have an m14 build which is in need of some optics. The use of the rifle will be for hunting and I'm really looking for a short to medium range optic to go on the build. I hunt in a brushy area with medium sized choppings so shots range from up close (20yrds ish to 250 yrds-ish).

I've been looking at the Eotech exps2-2 with a burris 3x magnifier. Fairly certain that this would cover the short ranges, but wondering what the average medium range that this optic setup could reach.

Realize that the answer depends on a lot of things, but hoping that some folks on here could give me some personal opinions or share some relevant experiences.

Thanks,
Ben
 
I have the EXPS2-0 and the EOTech flip to side 3x magnifier (whatever the exact name is) mounted on my 16" AR.

I can hit targets out to 200yrds all day, but I've zeroed it at 50.

The projectile will cross your "zero" point/sightline twice: once at 50yrds on it's way up, and then again at 200yrds on it's way down.

I've used these 2 targets (printed out and hung up at my indoor range). When the target is correctly placed at 50 yards, the optics dot will completely cover the colored portion of the corresponding target. The black ring will assist in correctly centering the optic over the target for a near perfect hold (depending on if you do your part). Just shoot your groups and use the adjustment references to quickly move your point of impact. This should speed up the zeroing process and provide an extremely accurate zero at the same time.

Here is a 25 yard targets that will give you a 50/200 yard zero when used properly when you only have access to a shorter range. These were made to work with standard AR sight height (2.6" - 2.8" over the bore) using averaged M193 / M855 velocities from a 16" barrel.

Place the target at 25 yards. Your point of aim should be at the colored / bold outlined portion of the target. Fire your group. Adjust the point of impact to the GRAY DOT in the middle of the target. If you follow the adjustment grid it will get you there. The math works out to give you a 50/200 yard zero.

Be careful to keep the optic's dot centered within the optic itself as much as possible when zeroing at this range as it is not entirely parallax free at 25 yards. Also, be sure to verify this at 50 yards when you can as there may be slight differences in each weapon that may alter the zero (sight over bore height, co-witness, barrel length, ammunition used, etc.).

Good luck
 
sweet targets, I use the military 25m/300m target normally, but I might give that one a try. any reason to adjust at 50y/200y over 25m/300m?

Personal preference. For reasons I don't want to commit to a public forum, I think 200m is a more realistic distance (for me anyways). Also, the 50/200 zero means the projectile is ~+1.5" @100 and ~-1.5" @300, so it's a middle ground

I prefer the 50yd zero. It has the lowest amount of deviation between 25 and 300. At 50 and 200 its zero. Between 50 and 200 its high. Past 200 its low. You might be surprised to see on the graph below that the bullet trajectory for the 25 yard zero rises 10+ inches above the line of aim at its apex! The bullet doesn't re-cross the line of sight until about 375 yards! A definite eye-opener for people who are using the 25m/300m zero that the Army teaches.

But, incase the OP wants the 25/300 meter target for optic:

thanks, I'm using an aimpoint TI and KAC 200/600m so I'm better off sticking to the 25/300m zero otherwise they wont co witness at all... and I'd loose the elevation adjustment of the KAC

Ya that's exactly what I was going to say. Good observation.
