Installed on Maverick 88
I had to drill and tap the receiver on my shotgun which I've never done before but I took my time and triple checked everything making sure the receiver was dead nuts level and lined up on my drill press before I drilled the first hole. I used a #28 drill bit and an 8-40 taper tap and Tap Magic lube. I am far from a gunsmith so how did I find my center line on the receiver you may ask...on the 88 there are 13 very fine grooves on top of the receiver I counted 6 from the left and 6 from the right the middle one lined up perfectly center at least to my eye. Then I measured 2 inches back on the receiver if you look inside the aluminum is a lot thicker there and that's where I drilled my 1st hole. I was nervous doing this even though it's a cheap gun but everything worked out and my rail is solid and lined up nicely. I used blue loctite on the screws then mounted a cheap red dot from Amazon I shot 20 slugs and some Turkey rounds the other day and it hasn't budged. If I can do this you can too because I'm pretty dumb just go slow don't rush it triple check everything before you crank on the bits. Good luck! :-)
