Question: Is this item good for Mossberg shotgun 930 combo, 12 gauge , 24" full rifle barrel ?
Document: As advertised, installed and works great on my Mossberg 500 shotgun. I would purchase again if I needed another sight.
this is for a mossberg 500 barrel with rifled sights dont look at the main pic. or go to williams gun sights web site and look at the model numbers
Product arrived exactly as described, packaged well. Installation was a breeze. Front sight blade fit snugly in the dovetail without any fitting required, and is held in place by set screw (Mossberg factory item). The rear sight was a simple remove and replace operation. I like the sight picture and the overall appearance of the firesight (black parts) vs the factory fiber optic (which is a clear sight with the fiber optic filament installed). The factory sight is a bit puzzling as both are Williams Gun sight items.
sights need some gunsmitting even if your shotgun has the stock williams sights, work great but could of being be better
Not sure why the factory item is different than the FireSight but I'm glad I got the firesight.
Big improvement in sighting your target. I would definitely get this item if you want to set your sights quicker than before.
These sights fit my Mossberg 500 Williams factory sights perfectly. You do need an hex head wrench for the front sight.
perfect fit, nice and bright, i havent tried them yet but im sure they will work great,i would recomend this product
Illusion in the advert.The product is not the photos, the sights come without the bases.
Based on the written description and the product photo, I made the assumption these sights would be a "bolt on" type of installation... Not only was it not, but it appears I need to buy other parts to even install these sights... I am not sure I am interested in spending more money on these sights and will probably go to a firearm dealer for items like this, from now on... The trouble in dealing with these details isn't worth the dollar saved...
Answer: no
