I think it is a 0.5 mm Allen but I may be wrong

I just grabbed a used Rainman UC kit. How can I tell if its the new version or old. I have to find a frame screw and not if I need 5/8 or 1"

Edit: Answered my own question: new version and definitely need 5/8

Question about the "valve seat" are we sure its a 9/16 18? or could it be a 5/8 18? just wondering, when i measure it, I get 5/8, but its been a brain fart weekend so just wanted to double check

All right, what are the threads on the TPC and in the bolt? Want to use my old short TPC to make adjustable bolt for another old nel based marker.

I believe the threads on the inside of the bolt are 1/2 x 20. I was speaking with Mike about cleaning out the inside of a dirty bolt, and he said to run a 1/2 x 20 tap through it to clean out the threads.

I have some new info and a correction to make from previously posted info. The specs come directly from CCI/Mike Casady on 3/6/13...

The inner diameter (I.D.) of the stock CCI valve tube is .180 (#15)

The spring rate of the CCI red spring is 15% more (heavier) than the standard (silver) spring. The spring rate of the CCI blue spring is 15% less (lighter) than the standard (silver) spring.

Correction to what was previously posted - The threads of a SC feed tube have a 32tpi pitch that tapers from .805" out to .855" and is .700 in length.

That is all.

Anyone know what the hard line is made out of? Stainless steel? 304L?

Looking to do a little bending wanted to know before I bend it.

Screw needed to attach the SC to OC clamping feed conversion is a 8/32 x 3/8" stainless button head.

Anyone know the screw size for mounting the butt plate on an adjustable T stock?

*EDIT* screw size is 10-32
