Must Have Sight Pusher
584713
Well made sight pusher that does a great job, simply and smoothly.  Put a set of XS Big Dots on my Glock 22, and it took all of 10 minutes.  Well worth having this tool for all your sight pushing needs.  Update, this sight pusher would not work with a Sig 229.  The recoil spring housing will not allow slide to fit in tool.  I took the bottom section metal out to accommodate slide, but there is not enough support, and the slide tends to ride up on the side being pushed.

Love it. Maximum fiber optic illumination I've seen in low light conditions. Like other sights this one two major adjustments one for windage and one for elevation. One set screw for each pin not just to lock each pin in its position, but each pin rides up and down on a set screw to make precision minor adjustments of each pin. Most other sights you loosen the set screw then move the tiny sights with fingers try to hold in place while retightening the set screw. Not this one. Turn the set screw a little for small elevation adjustments or a little more for a larger elevation adjustment. Easy to make adjustments when changing from field tips to my practice/dummy expandable broad heads.

I use these all the time when sighting in my rifles.  For the amount of them you get in a package, they are way better priced than you will find retail. The peel and stick is another great feature. You can see your hits, or lack thereof, at good distances without the use of a spotting scope.  I highly recommend these for setting up your scope sight in's!

I really like this sight.  This is the second one I have bought I bought the first one for my ar-15 and this one I got for my new ruger 10/22.  They are super easy to sight in, and stay sighted in.  I really like how you can make it green or red and multiple different cross hairs and dot shapes.  They also send you extra batteries with it which is awesome.  The price is unbeatable and the quality is really good.  My friends who have sights that are similar cannot believe how cheap it is when they have paid $200 or more dollars for sights without as many options.

Love these sights. I have mounted an optic on my DPMS AR-15 and did't want to have to remove the optic to be able to shoot if the optics fail in a SHTF situation. These offset sights are the answer. With a quick rotate of the weapon you have iron sights, don't have to flip them up and they won't go anywhere. I have shot about 2000 rounds through the AR with these on, thrown in in my truck and bumped it around a few times. Sights haven't budged. These are very similar to others on the market, if not the same sights without the branding. Great buy and save you about $200. You can not go wrong with these.

Install was very easy, make sure to use loctite!
This sight is advertised as being able to use a shell casing to manipulate the wheels, I simply can't do it. I really recommend the tool they sell for this to make adjustments easier. Otherwise, this is a way better sight than the stock mini-14 one.

I used this on a .40 cal Springfield XD(M). For some reason no one in my area wanted to or could do the sights on the gun. I watched a video on youtube. I placed the slide in this device and then placed both in a vice. I did both the front and the rear sights. It took me about 30 minutes to do both and I have never used a sight pusher before.

This was the only sight alignment tool that had calibrations to make the job way easier.  I've reset sights on several different pistols and revolvers without a single issue.  If you do your own work this is a must for a built.

These went in easily with a sight pusher tool. They look and function great. Other people say to use the Sig sights on the XDs pistols but if you measure them there is a very small difference in height. Get the correct replacements. These are the best sights on the market in my opinion.

I have sightmark sights for various calibers and these work as advertised.  Makes bore sighting laser grips a much easier endeavor by just having the "dots" line up at whatever distance you want them set for. HIGHLY RECOMMENDED

Much more accurate with this sight. Picks up the front sight quickly and bulls eyes are easier. It extends range of shooting.

I love this sight.  2 inch groups from 25 yards.

Built like a tank should last forever.

May get the magnifier cause my eyes are getting old.

The Sightmark 9mm Lugar Boresight is a good tool to have with your gun supply items. It makes sighting in your guns extremely easy and saves on ammo.

My second set of these owned now and I love them. Will reiterate my first review on my other block install... These sights are awesome. Did a lot of thinking and research between these and the fiber optic offerings. They glow at night, and the front sight is painted for daylight. So they are perfect in any condition, unlike the fiber optic type. Trijicon is also know for quality and long lasting glow, 10 years I'm told. Definitely worth the higher price. Only thing is, you must also buy the rear sight install pusher. Can run 100-300 bucks, or take it to your local gun shop for prob a $30 install. Don't bang on the rear sight yourself!!!

This is a well built sight pusher. Don't see it deforming due to soft metal. Got it I the mail and replaced sights in four pistol and has already paid for itself in gunsmithing fees.

Very good sight built strong and in the US. For myself the sight is a major improvement over traditional sights. Their is a bit of a learning curve in the beginning but when you start to practice with it more and more it will become quicker then iron sights. Mine has been mounted on a Glock 19 MOS and a FNX 45 tactical. Both are perfect hosts for this awesome red dot. I would also suggest getting the RMR mounting plate with this because the sight itself doesn't come with screws or the sealing plate... Which i am not very happy with Trijicon about, if i'm going to shovel out $600 for a sight at least include the $18 sealing plate and screws with it.. i mean really.. but over all performance Is completely worth it so far.
