Well I mounted my CenterPoint from my 10/22 on my 15-TS and I didn't use a scope mount. Just mounted it to the rail. Where my eye relief is the scope is actually far enough forward to still access my charging handle easily.

I will hopefully get to test it out this weekend if it stays nice outside! I can't use the front rubber flip up cover though as it hits my top rail.



Front rubber cover just barely on to keep dirt out.
