MEPRO Tru-Dot tritium Night Sights Compatible with Benelli M1S90 M2 M500 Green tritium dots Glow on Sight self Illuminated Meprolight Fixed Metal Sights for Low Light Conditions

Nice product. The dots on the rear sight are fairly small, but the one on the front is very nice. The sights are easy to line up in darker areas and really aid in getting a good sight picture in lower light situations. The sights were very easy to exchange with the factory sights. In order to properly tighten the front sight you need a 7/32 wrench. You can do it with some small needle nose pliers, but you will round out some of the edges. Amazon had an adequate small wrench set for a decent price. Now I have a whole bunch of smaller wrenches in case the need ever arises again.

Got my Meprolight sights lighting fast in the mail. They were very easy to install, just make sure you get a hold of a 5.5mm midget combination wrench or you will have a bear of a time removing the front sight nut. I could only find a 10pc set of the wrenches at Sears. The sights themselves are very well machined and finished, the tritium is bright and easy to see with the three point setup. I would highly recommend these to anyone with an M4 that is tired if the old charge up sights.

Tried to install these on today. The vials had satisfactory glow. The front site post is made from too weak a metal, the threads will yield and fail soon if not during assembly then likley during use. (I'm a mechancial engineer and I build scientific instruments for a living. I make parts with threads much smaller than this everyday). The rear sight was unusable. The windage threaded hole was failed from the factory and the benelli screw would slip through with nary a snag. Junk.Very disappointing. Abysmal quality control. I reached out to Meprolight directly since this isn't the sellers fault.

I've made Meprolight Tru-Dot night sights mandatory upgrades on all of my Glocks; so I decided to try a set on my Benelli M4. I'm glad I did, these sights did not disappoint. Quality product as always!

First, I'd like to see someone remove the front sight on my Benelli M4 with a 5.5 mm wrench. Way too big, the correct size wrench for my gun ( can't speak to anyone else's gun) is 7/32, much easier to find, so check before looking for a 5.5 mm. Unfortunately I didn't, guess I can sell my useless wrench. Pretty easy to install, the M4 is such a well made gun, the sights are no exception. Back to the sights, I put Meprolights on all my Glock pistols, wish these sights had larger tubes like the handguns, these are tiny and very difficult to see in daylight. I will probably end up changing back at some point. Overall they're just okay, Meprolight should redesign with large white rings outside the tubes.

Price rocks but glow is extremely weak. I suspect these might be this low on price because they are very old stock and the tritium is worn out.

I felt the brightness was appropriate for its intended use.

Great sights. I put them on my Benelli M4. I like the contrast between the rear and front sights. It is very easy to get on target and they are plenty bright. I am very pleased and would highly recommend.
