I'm an old iron sight guy but as I get older, I find I need a scope to see my target. I only shoot for target practice now at an indoor range at 25 yds and 50 yds.

You are welcome! Remember, 1/4 inch clicks at 100 yards equal 1/8 inchs of movement at 50 yards when sighting in your rifle.

The parallax is set for 100 yards on this scope. Bore sighting is a great place to start and then make the sighting in adjustments to get dead on at 25-50 yards. This compact scope should be perfect for your eyes and the will focus just fine at the distances you describe.

If you have not physically zeroed this scope on your rifle ,you will need to. I wouldn't just bore sight it and trust 100% that it's going to be zeroed at 100yds with out putting rounds down range.

If you go to Nikon's website, they will be able to tell you how to adjust your zero based on the yardage, the rifle, and the specific ammunition you are using. The website is great. http://spoton.nikonsportoptics.com/spoton/spoton.html

Everyone who answered is either not understanding the question or talking out of their butts. The P-223 could very possibly be too short to fit in this mount. I would go with the two-piece P-series mounts from Nikon that are designed to work with that scope. Sorry I do not have the absolute answer either, but I am not pretending to.

Correct, this scope is dialed in for .55 gr bullets at 3240 fps. If you want to shoot heavier bullets accurately I would suggest the M-223 with BDC 600 reticle. This will allow you to use Nikon's Spot On Ballistic Program to dial in your rifle, scope and ammo choice.

It takes 1" mounts. If you're mounting it on an AR-15, I highly recommend the Nikon P Series mounts. Also sold by Amazon. On mine, I simply removed the carrying handle on the AR, and using the Nikon P Series mounts, mounted on right on top of the receiver. You might think that the front sight would be in the way, but it's not. This is a great combination. If I might make one more suggestion. If you are mounting it on an AR-15, I highly recommend you get a Sightmark laser boresight. I have them in 223, 25-06, 270,and 30-06. Also sold by Amazon. They will save you a lot of time and ammo. I sure hope this helps you. If you have any other questions, I'll be glad to try and answer them for you.

I would zero at 25 and then tweak at 50. This a good scope for 50 to 100 yards. I also have the P-223 3-9X40 for longer distances. I've read good things about the P-223, but haven't had much time to use them yet.

You won't need a red dot on top of scope even though there are rails on the top and side to mount it. On 3 power you can still keep both eyes open and still see the large circle red dot for CQC applications without the need for another red dot. The red dot on top will be pretty high.

the p-223 was designed for the 223 round with 55g and 3250fps.......nikon has other scopes that may be better?

I think that what is confusing you is some are saying it has "visibility" dial and some are saying that it does not. The "visibility dial" is used to focus in your cross hairs only. You would want your cross hairs as clear and crisp as possible. However, you CANNOT adjust the magnification of this scope. IT is a straight 4X magnification. If you buy a scope with magnification adjustment, it will say something like 3 x 9 adjustable magnification.This is a good scope for a .22 caliber up to 75 to 100 yards. I have seen these mounted on .22 caliber handguns with raised rings so that the shooter can use the Iron sight or the scope.

The best thing I can say is wen I was in the Marines, our battleground zero (standard/default zero) was 300 yards. I didn't have an eotech in the corps. Just iron sights on my m16a2 (20" barrel). I can also tell you the trajectory of a 5.56 NATO ball round at 36 yards is the exact same as it is at 300 yards. We zeroed at 36 yards. Again, iron sights only. It should be the same with the eotech. The range you choose to zero is all about the trajectory of the round. I don't see where an eotech would change where you should set your zero. Everything I know about my ar, I learned from my marine corps service rifle 20 years ago. I hope this helps.

Hi my name is tom I put one of these mounts on my dpms upper with my flip up rear site and it clears fine. But you must remove the scope to see your front iron site depending on the power of the scope it will be to close and you won't see it. The ruger has a longer rail than my upper has so you will be fine. keep in mine when you adjust the mount to your rifle mark you lable where you mounted it so you can return it to the same place on the rail each time. after installing I check my set up with both a lazer bore sighter and 100yds paper 5 shot group and 5/5 on returning with in a quart inch of my first zero. I am impressed. Hi my name is tom I put one of these mounts on my dpms upper with my flip up rear site and it clears fine.

This is an amazing red dot that performs well when paired with the .233 cartridge. However the question is how high do you want your optic. I have this model (with the cantilever mount) and the centerline ( middle of the lens) is 1 7/8 of an inch above a flat top AR. Depending on what stock you use. Personally since the optic and boreline will be closer I would go with the Strikefire 505 for your Ruger.

As a few others have stated, for it being a low fixed power scope it is on the "weak side" of pin point accuracy for 300+ yards. But as a person who has 2 of them mounted on AR's and shooting 55gr bullets all the time, it does work for 300 yrds without the need of using the BDC and I am able to hit a 12 inch target 8 out of 10 times. Know your ammo and if your eye sight is "ok" you should be fine. Don't be discouraged from buying this scope, it is a great scope with crystal clear field of view.

For the BDC reticles to work properly, the scope needs to be zeroed at 100 yds. That being said, experimentation on your own at different distances may provide other workable solutions.

2:03 PM (2 hours ago)to Amazon I am using the UTG CQB Red/Green Dot Optic Model SCP-DS3840W. I only use the rifle for targets and this works great. We shoot at 4" steel gong targets from 100 yards and only miss when it is shooter error. This model has locking windage and elevation adjustments. The fellow I shoot with does not have locking adjustments on his optic and has had to reset each time we shoot. I am very happy with my setup. In order to mount both you will have to have a top rail on your handguard. I replaced my stock handguard with the UTG SSSR Model 4/15, easy install.

I mounted it on both a DPMS LR308 and an AR15 I built, both flat tops. The 308 has an A2 front sight, it does not interfere, the red dot sits right on top of the front sight (if your eye is where the rear peep would be, if folded up). I have fold down sights on the 223, but the red dot aligns absolute. I like it better than the lower 1/3 view with the straight mounts..

Shouldn't be a problem for 223 but have not used it for 556. 556 usually requires a swage tool before priming.
