Decided to keep, at least for the time being a Hyperframe that I recently got in off Ebay. I got it up and running really well. Valve was marked Field Rental, but hoped it would take an L10. Nope. Had to mod it to work. BTW you need a 3/16 drill to do this. Drilled it, got it cleaned up and after screwing around with carriers finally got it to work.... Then it started venting out the back. Crap! I know some of the older pistons could not take the pressure of the L10 so I swapped the L7 back in. Started venting again. Double Crap!. So I pulled it back out, and took a look at the reg seat. Looked ok to me. It was the one that came with the Aluminum back, but decided to dig around and get another out of the parts box. Put it back together with the L7 and poof!, it worked. Started feeling cocky and decided to go back to the L10... After going up a carrier or two to get rid of the bolt stick, it worked like a champ. No bolt stick, L10 engages, and no venting out the back. It's a good day!
Now my question is this. If I hadn't fiddle around with swapping out the reg seat, I would have either just stuck with the L7 or maybe gone out and bought a new piston to swap out. My question is, is there any way to tell the difference? Any marking? Any differences? And on a technical side, what is the exact difference between a piston that can take the pressure of an L10 and one that can't? Something tells me that the only difference is that one is adjusted differently.
Here's a pic so far:
Future plans call for:
1. - 13 or 22 CI tank*
2. - ULE milling on the rail
3. - Possible upgrade on the Hyperframe
4. - Clamping Feedneck
5. - Dual Detent?
6. - Anodizing
