Ok, so now I feel about as dumb as dumb gets. I call H&R to specifically ask and made sure I said the screw size for the front ramp and it has just one screw. So, she says #6-48, WRONG !! After this I called XS and told them I need the front ramp for my gun because the gun just hast a straight blade single screw, no dovetail. OK, sir no problem. I get it and spend saturday cleaning the gun and getting it ready for it's first trip to the range. Time for the XS Ghost Ring now, The screw size is not a #6-48, it's smaller and now I can't put the ramp on that XS sent me for an additional $28.00 I might add. Kinda surprised about that, seems like they would send what you need to install the thing, but whatever. I just want it on at this point ! Does anyone know what size this screw is, could it possibly be a #4-48 ? Or is it a #8-40 ? Thank you all as always especially to Mr.Quickdtoo !
