...................................I was just thinking this morning how several relatively new technologies have come together to drastically change PCPs over the last few years.... The SSG gave us the ability to eliminate hammer bounce, and reduce cocking force compared to an SSS with gap.... The drop sear triggers on the MRod and PRod supplied us with readily available, good quality triggers, which allowed the use of MDS hammers.... The MDS hammers made the use of aluminum main tubes more practical.... and of course the SS and Cothran Valves drastically reduced the cocking force, particularly in big-bores.... and allow even lighter MDS hammers without excessive spring force.... The balanced valves also allowed the use of larger valve throats and porting in guns with limited hammer strike capability.... unleashing an FPE capability not previously possible in those configurations....A decade after I got back into airguns, I suddenly feel like there is so much new to learn.... and that PCPs have entered a new generation.... It's exciting to be a part of it....Bob

I'll probably put my foot in my mouth right now, but the bulk of the innovations are from individuals. The larger companies have come up with nicer guns, different air gun designs, more accurate guns, improvements on existing technology, and made the field fairly competitive. But the thinking outside-the-box type of innovations......... hmmmmm.
I swapped the 6 mm upper onto the unregulated gun tonight and filled it to its MSWP of 4200 psi.... I set the SSG to just a whisker of gap and fired one shot to settle things, topped it up and fired two shots with the 73.4 gr. bullets.... 1028 & 1029 fps (173 FPE).... Then I did something I have just been dying to try ever since I came up with the idea of building a 6mm.... I loaded up a 1.8 gr. Airsoft BB, topped it up to 4200 psi and took a bead through the Chrony.... 2093 fps.... repeated it.... 2097 fps.... once more.... 2087 fps.... That gives a three shot average of 2092 fps (17.5 FPE) with a basic PCP, just shooting very light ammo.... No special equipment, just a standard SS style valve, porting that turns through 180 deg., and a rifled 29" barrel that is a poor fit on the BB.... it will actually roll out the muzzle if you hold it pointing downwards.... Running air at room temperature (the pressure in the 300 cc reservoir dropped ~ 250 psi each shot), not Helium.... Lloyd still holds the record at 2162 fps.... but he better be looking over his shoulder.... Bob
incredible!! in the airsoft world ,you would be the messiah

Took our EMT 15 minutes to get that bb out, with lots of pain. The guy almost passed out. I think a BB that fast could actually kill someone from close enough. Snipers in airsoft generally aren't supposed to shoot from less than 100 ft at most fields, but this guy ran right in front of a teammate when he was breaking a shot.
Nice one Bob, gun looks very good! Not to take anything away from you but Lloyd was shooting lead pellet not plastic if I remember correctly. Marko
