Instructions
How to install the roll pin in the front sight. It is easy to mess up the roll pin when you first try to install it. Read below to avoid the pitfalls. Not all SIG 556 series weapons come with a front sight installed. So issues like this arise most often when the user is NOT first removing a similar front sight from the weapon and thus is completely unfamiliar with the requirements. There is a first time for everything and that is a part of any weapons system. When SIG installs these at the factory they have a special fixture or a second person to hold the weapon. While a fixture or third person is NOT required it sure makes it a lot easier. All you need is someone to hold the weapon while you hold the punch and hammer. Be sure that the hole in the donut and spline are clean / free of metal shavings. The most common mistake that leads to messing up a roll pin is not having the hole in the spline / adjustment bolt and the hole in the round / donut wheel lined up. You will have to use a punch or something to be absolutely sure of the alignment. Use a 1/16” punch or 1/16” drill bit or 1.5mm allen key… or look around the house and shop for something that fits through both. The number of turns to get the holes lined up is between 2.5 and 3 full rotations (you have to look down the hole). The windage bolt should NOT go past the point of being flush with the outside edge of the donut. It is a lot easier to file or grind down the roll pin at one end and then gently collapse the same end with a vice grips of pliers so that it just fits / sits in the hole of the donut. This will free up one hand. This is almost a requirement.

MFI hit this one out of the park! I bought this one without the adjustment wheel as I had an original SIG SANs wheel set already (so saved some $$$). Mounted it in seconds on my SIG 553 SBR, centered it with the line on the sight and gas block and it shot dead center at 75m without any adjustment (gun was previously zeroed) and I am runinng the welded on diopter. Great product at a SUPER PRICE!!!

Works perfectly, super fast shipping and outstanding price!!
Quality workmanship, I can really tell that this is a USA product. Why by Swiss when this is as good if not better at half the price?

Below is my review of the MFI Diopter Rails. I also bought this sight to use while I wait for the MFI Hooded front sight to come in.
Super fast shipping too!
I have been following this product for years and I cannot thank Mike at MFI enough for sticking with this project. I know how many problems he has had over the years with this.
Anyway I got one of each color, Black and Gray. So I will double post this on the other color too.
Fit is perfect. So easy to install and what a differance it makes. The black is almost a perfect match to my SIG 556 upper. Swiss style markings make this product even cooler. Love the Swiss Cross. I have only test fired perhaps 250 rounds as I just got this a day ago. Works perfectly at 100 meters. The 200m position on the drum appears to be right as well. I an not sure as I am using military ball ammo and I do not normally shoot past 100m anyway. I also really like the fiber optic option. I ordered the front hooded sight as well, but as I was in such a hurry to get one I bought the MFI non hooded SIG SANs flip front sight and everything lined right up and dead on. I cannot wait for the hooded sights to get in.
On the Gray Diopter... well this one went on my SIG 551A1 from CDNN and the color match is very close and may be perfect, but the MFI rail color is sort of a semi matt finish where my receiver and lower are more flat. Still way better that the rail that came with the 551A1. I also put the Black rail on the 551A1 and as I have black Swiss furniture on the 551A1 the black MFI rail actually looks great and not out of place at all. I have not shot the 551A1 yet.
Fit and finish are superb. I do not mind the casting marks as they are a reproduction of the originals I am told.
Again... THANK YOU MFI... a small company (one guy I am told) really came through!
