Ordered a Gamo Arrow Monday from PA. Got here today. Came doubleboxed from GAMO already. I knew from the YouTube reviews it was a 40 shot at 16fpe gun in .22 so didn't bother shooting it stock. Takes about 90 seconds to disassemble and another 5 minutes on the lathe opening up the TP to .147" and doing a spring swap. Valve and barrel are already ported above that. Used a .059" wire diameter with .48" OD and 2" OAL spring. Reassembled and aired up. Compressor sheared the drive shaft last week so handpumped the gun. First full takes 3 minutes maybe but now getting 20 shots at 27fpe in the sweet spot of the curve and only 55 pumps to top it back off. I am only filling to about 3100psi down to about 1800 psi. 125cc tube pumps quick. Magazine handles standard polymags too so that's a plus. I have cphp, H&N FTT, Hades, 15.89JSB, Polymags and 18.13 JSB to test this weekend and I'll do an update. Trigger is a little long but smooth and shoulders really nice. Wide foregrip feels great. If accuracy is good out to 25 yards it should be a great squirrel gun this year.
