MOGC Posted September 16, 2007 Share Posted September 16, 2007 Hello gentlemen, I'm a newbie to this forum, looks like a lot of info to be found here. I did try a search, however, I couldn't seem to find the answer to the following questions. I just bought an M1S90 Tactical Model with the 18 1/2" barrel that accepts screw in chokes and has open iron sights mounted on the barrel. The front is a blade type that appears to be soldered solidly to the barrel. The rear sight has me a bit curious. The rear resembles a "fixed sight" rear handgun type arrangement. How does one go about "sighting in" this sight and moving point of aim to strike the same place as point of impact? I guess that it can be drifted for windage? There are two tiny holes in the sight, do these have locking screws to secure the blade? What about elevation changes that may be neccesary, how would this sight handle a necessary change in elevation? Any information will help. Thanks in advance!

MOGC Posted September 17, 2007 Author Share Posted September 17, 2007 I appreciate the reply. However, that is not the rear sight on my barrel. My rear sight resembles a standard "fixed" sight as found on many handguns. Look at page 20 and a few of the following pages for a view of the rear sight as found on my barrel. There are no windage/elevation adjustments, and, no details in the manual you kindly provided via the link. Quote Link to comment Share on other sites More sharing options...
HOGWILD Posted September 17, 2007 Share Posted September 17, 2007 is the ones that say tactical above them one this page like yours? http://www.benelliusa.com/firearms/partsAccessoriesSights.tpl Quote Link to comment Share on other sites More sharing options...
MOGC Posted September 18, 2007 Author Share Posted September 18, 2007 Nope... My front is a "shark fin" type blade that is fixed to the barrel with no allowance for adjustment. The rear sight has a very, very, low block that also seems fixed to the barrel via soldering solidly. There is a dovetail in this block and a standup blade in this dovetail, very much like many rear sights on handguns. In fact, the sight picture is exactly like a handguns. On the back side of the solid block are two tiny little holes that probably have a couple of set screws that secure the blade sight for windage. My question is what can a guy do for elevation with such a set-up? Are there various height rear sights for the dovetail? Also, how can a person loosen those tiny set screws in that rear base?

tucker301 Posted September 18, 2007 Share Posted September 18, 2007 You have fixed sights. The weapon is a shotgun, aka scattergun. The sights are designed to work in much the same way beads do on sporting shotguns or fixed blade sights do on close range handguns. They get you on the target in general; which is usually just fine for a shotgun. The dovetailed sight can be tapped right or left for some windage adjustment and the front blade can be filed down for elevation, but that's about it. If you want more exact sighting for the weapon, then consider mounting a red dot or holo-sight of some kind. Did I mention it's a shotgun?

MOGC Posted September 18, 2007 Author Share Posted September 18, 2007 Did I mention it's a shotgun? Is the sarcasm neccesary, or, is that an intiation for welcoming a new guy to the forum? I guess slug shooting falls under the "scattergun" umbrella? I'm not sure of your experience, however, it is helpful to have sights that allow some adjustment for slug shooting. Tightly choked shot loads do not always strike to point of aim and adjustment is a handy thing for such applications. Less so perhaps for for other game or sport shooting, thus a scattergun could well fit those needs perfectly. If you want to tell me something I'm not sure of, enlighten me as to those two tiny holes in the back of the block - are there set screws securing the standing rear blade?

tucker301 Posted September 18, 2007 Share Posted September 18, 2007 If this is you, then there's a screw. 043C Look, all I'm doing is stating the obvious. You have what you have. If you want something better for slugs, then I suggest an optic. Quote Link to comment Share on other sites More sharing options...
MOGC Posted September 18, 2007 Author Share Posted September 18, 2007 That is my barrel. The diagram is helpful, thank you. Quote Link to comment Share on other sites More sharing options...
