If you are looking for the picatinny rail Google Mesa Tactical part# 92370. I found it for $29 at one site. Most other sites are $30 somthing. The Mesa 92370 should work with Remington pre drilled recievers. If you just want a weaver rail you can pick up a Weaver 429 rail for $9 that will fit Remington recievers. Hope this helps.
