I'm about to send off my ps90 to be engraved for SBR, and I cannot get the rail off. The front screw came out (at sight adjustment) but the screw on the TOP of the rail towards the rear, will not budge. The screw even seemed to strip the hex opening a little so now the allen key wiggles in the hole and won't grip. $%#$%#$. What do I do now other than spend a few hours with a dremel and a cutting wheel and SLOWLY cut the rail off? :cry:

For a minute, I was thinking that you were trying to get the top rail off. But after thinking more about it, I realize now it's one of the side rails you need to remove so you can do the engraving.

Do the screw extraction using screw extractors like Lester just posted and it should come right out.

If that doesn't work, would you object to engraving on the other side of the receiver instead?

If you can't get the screws off of the other side also...you're screwed! Sorry, bad joke. I couldn't resist

yep, top rail. going to replace it eventually, so I want that ugly afterthought of a 1913 rail gooooone. I will head to Lowes on Sunday, and report back. Hopefully I don't loose a finger, I'm not the most mechanically inclined :th_1087::th_1087:

Suggestion: What you could do is, if you're not worried about the rail, get a variable speed electric drill and a drill bit that's about the size if not slightly larger than the screw itself (threaded end) and carefully/slowly drill the head of the screw out. You'll be able to remove the rail and a portion of the screw will be exposed above the surface that you can grab a hold with a pair of pliers and twist/screw the remnant out of the threaded hole. I've drilled many O stripped allen head screws in the past and this is about the best way, for me anyway, remove a problem screw. But, if your not mechanically inclined you may want to have someone that's a little more capable to perform. Either way, most of the screw extractor tools will require some kind of a drill to be involved. Good luck!

OK, my ignorance is going to show itself again. The 1913 rail is the one that has the raised forward section? What would it be replaced with? I look at my PS90 and see the ramp is sloped so without using the triangle shaped rail how would you get a level surface for optics?
