Carter, your 2100 is healthier than any 2100 or newer varients I've had so far. Good work with that one!With the Legacy's piston, is it a drop in fit for the 2100? I'm thinking of picking up either a 2100 or Legacy as a project, as to not ruin the one's I have and not sure which would be better, putting a Legacy's piston in a 2100 or a 2100's receiver on a legacy. I've saved parts from older/broken guns to do either-or. My first Legacy 1000 had lots of zip, but the receiver cracked on me, didn't have a chrony then to test. The following two I purchased were noticeably weaker making 6.7fpe and 8.5fpe @ 15 pumps, my 2100 beats them both with 6.5fpe @ 10 pumps, all per my notes. The Legacy's just didn't make any power at 10 or 12 pumps, but enough zip at 3-5 pumps for plinking.
Took a little effort (...and a few words) but my 2100 now sports an aluminum pump piston. I definitely notice a difference in pump effort towards the end of the stroke. I'll chrony tomorrow and post up results.
The newer aluminum (2100) pistons used on the 362 have a plastic bushing that prevents metal to metal contact.Not sure about the original Legacy 1000 pistons.Looks like it would be easy to modify an existing piston and make a bushing.
All this talk about 2100s brings back fond memories of my modded 2100.Bought it off Amazon in 2012 for $50 delivered.It was accurate straight out of the box.Had the full plastic bendy piston so not very powerful.After several mods including a FT piston/valve it gets 825 FPS with 7.9 CPHPs.That's with 10 pumps, 15 pumps and it gets north of 900 FPS.Pumped it up today and it still gets 825 FPS, 11.94 FPE with 10 pumps.
Sealing the probe and transfer port along with the metal piston should get you close to my gun.I took out all the BB parts since I don't shoot BBs.Makes the gun much easier to assemble.
Thanks fellas. I have never shot BB’s out of this one. I’m thinking about replacing the probe with a piece of brass tubing. Tubing would be about .175” in outside diameter. I’d file a groove around it to hold an O’riing. The last approximately 3/16” would be filed into an inverted U opposite the transfer port. Hoping that will reduce obstruction of the port but still provide sufficient bearing surface to push the pellet smoothly into the breech. What think y’all?
