Everyone who has a Longshot all know of its weak boltsled. I know there have been many guides on re-enforcing boltsleds, but this is just how I did mine and I felt like it was about time I gave back to the community!
Something to cut sheet metal
Some sort of strong Glue
Metal Wire ( i.e. coat hanger, insulation supports....)
Sorry, no in progress pics, as I forgot to take them. (Oops)
So here's what it looks like all reinforced:
There are many write-ups on this, so I won't go to in-depth on this. Rogue has a very nice write-up seen here.
Basically, what you're going to want to do is trace the inside shape of the boltsled onto your sheet metal, cut it out, glue it on, clamp it in place, and let it cure.
After it cures, make sure to sand down the metal so that it doesn't rub up against your clips.

here. Tip! Try to make the wire as long as possible to widen the area it reinforces.
I reinforced mine with two wires on both sides.
Once everything is all done, you can replace it back into your Longshot and enjoy insane ranges! I've used this in my Longshot which has a 3b and k18 spring combo and it hasn't shown any sign of stress yet (I made this back in November '11). Hopefully this was a helpful write-up. :)
