There is very little info on the web about the 500SPX its mostly 930SPX but i feel mine is needing the spacer Mossberg has been using on those.

I checked for the canted sight,mines straight

so thats the biggy imo.
Ive hunted for a taller fiber optic insert and to no avail.
From what ive read about the 930 its spacer is what i need,but i have a feeling that will require a barrel replacement and id rather only do that as a last resort.

Honestly i bought the gun as the sights were a big selling point since i plan on alot of range shooting since SG shells are as cheap as 9mm now.

At 50' im 3" high with rifled slugs,but this is no hunting rifle,its HD only.
So at the average 7 yard shots with 00buck id say its possibly 1" high and thats nothing.
I could NOT test this as the range i was at only allows SG shooting at 50' ONLY.

If anyone knows of replacement higher fiber inserts i can do myself pls lmk,but the must be made for the gun or so close i can make it look stock.

For those unfamiliar its an AR style front sight,odd on a SG i know.But i really like it at the range.I did look for AR fiber inserts locally but didnt see anything,but i havent done a good web search yet.
