[How to raise front ghost ring sight blade on M1 S90]

I bought a used police trade m1s90 that came with 14.5 in barrel and ghost ring sights.

if I adjust the rear sight all the way down I am still 6-8 inches high at 25 yards with federal LE buckshot.

is there a way to shim the front sight to raise it?

the sight blade that came on the gun had a small washer under it but it does not raise it enough to make much difference.

 

thank you

Got it figured out

Can someone please explain to me which way the spring goes into a post 2001 rear ghost right sight?

it seems that it goes under the sight but I wanted to ask before I broke something.

Thanks

Great idea. My brother has one so I can switch with him. When I got the gun I assumed it was normal. Rob Roberts told me to run a case of shells through it.

The gun was like this when I took it out of the but plastic box it came with. Magazine tube feeds fine.

I just got a new m2 in 20 gauge. It functions fine with turkey loads but with remington heavy dove loads the bolt gets hung up on the way back. The top of the bolt is wedged against the bottom of the barrel extension.

 

When I got the gun i could hardly get it to go together. I sanded the top of the barrel extension with 400 grit sandpaper and finally got it to go together.

 

Do I just need to shoot it more to break it in? Rob Roberts told me that these guns need to be shot more than the earlier guns. My other benellis give me no problems

 

I have shot 100 rounds through the gun bring to break it in. I have cleaned the entire gun and still have issues.

 

Any ideas would be appreciated. I was thinking of polishing the top of the bolt and bottom of the barrel extension. I can't send it back to benelli because i have had a trigger job, forcing cones lengthened, and the gun camp dipped.
