What is the inside diameter of a scope mount and is it the same size dimension wise as the $9.00 I posted? Also is it quick release or mounted with hex screws? Lastly what is the price of their scope mounts?
Scope mounts typically come in two sizes: 1" and 30mm
Walmart most likely only has 1" ones, the 30mm rings are way too large. These are made to fit a 1" scope tube, but depending on the brand will vary a small margin, larger or smaller.
Weaver Quad Lock rings have two bands that clamp the scope with a small thumb nut to tighten the ring to the rail. Probably in the 10 dollar ball park for a pair of them. These would be quick detach, and youd have enough for two lights. They also come in a few different heights, low-medium-high, depending on how much drop you want.
Here is an example on my night critter getter, I used a modded River Rock 1AA in a standard 1" scope ring. I used regular o-rings around the head of the light for a spacer to fill the extra space (the light head measures 7/8" and the ring wouldn't close that far, o-rings were rolled in the groove for the clip, then the ring tightened down) this works well and provides some shock absorbing.
Phone photos, sorry
You can see the o-ring in the picture above, there's about 6 all together between the top ring clamp and the head of the light. Also note this is a tip-off mount (not the one you want, this ones is made for a .22 rifle) you'll be looking for a weaver (or Picatinny) base mount
From the Side. This little light allows me to see a possom through the scope over 100 yds away.
