I bought a 12" long 4130 steel tube from onlinemetals.com. The measurements were .25" Outer Diameter x .058" Inner Diameter x .134" thick walls. I wasn't sure if that was the proper size, but it was close enough and it worked out well. Not to mention, a whole foot of that material is like 6 bucks...
I rivet my receivers but am having a helluvea time with my center support. When I try to press the end of the rivet, it just bends over instead of getting fat and shortening. I'm trying to find a better alternative than a Tapco center support sleeve and rivet. I'm just having bad luck with this set up.
gogetumnow, I couldn't pull up the 93265A492, only the 93265A490. I found it toward the bottom of the page in the middle right side. But no ...492. Is it just a threaded sleeve that you screw to the sides of the recevier with a 10-32 screw?
I just buy a hardened non threaded solid rod at the hardware 3 feet long for a few bucks. Can make 25 to 30 of the center supports out of it. Just cut it to the right length and rifle drill it on the drill press. Thread the ends with a 10/32 tap if screw building or leave it alone if a rivet build. It has worked for me. ak'sr4me
