So my entry to the world of PCP began with a couple months of research before finding the forum here, tons of great info and some very helpful folks here and Im so grateful for that. I ended up staying with my original and most researched choice, the FX Impact M4, the Copper color in .22 cal. Kind of a "damn the torpedoes, full steam ahead" moment, despite the negatives Ive read about here. Im happy to say that my particular M4 seems to be just fine. Shout out to the fellas at The Pellet Shop, the rifle arrived fast, charged to 260 BAR, and fully tuned to my choice of pellets. They also threw in a free t-shirt, pellet saver band, and a bag of Twizzlers. 
I mounted an Athlon Midas Tac 6-24x50 scope with MOA reticle and 30 mm tube, great combo!
Im shooting JSB 18.13 pellets. Reg, came set at 110, 15 on macro, micro set a shade over 2.5, Valve adjuster shoes what looks to be about 4.5 lines. This morning my Magneto speed V3 chrony showed a high of 915 low of 908, avg 911, ES 7, SD 2.8 over a string of 10 shots. With all the rain my shooting has been limited to out the bedroom window at distances varying from 20-35 yards, but let me tell you this thing is impressive. with a lull in the rain yesterday i was literally smashing flies at 20 yards. the giggle factor was off the charts.
I recieved the M4 on the 1st, as I stated the reg was set to 110, over the first 24 hours it dropped to 105 but has been rock steady there for 3 days now, assuming the drop was temperature related since my house is quite cool. The bottle pressure dropped to 255 as well. I dont see this as an issue, i expected things to settle a bit. My first refill came after the first 175 shots, bottle pressure was 145, figured filling early would avoid loss of performance. So far Im happy as a clam, great looking rifle that doubles as a fly swatter, no apparent issues. Hopefully the weather clears soon so I can stretch out the distance.

the 18 gr .22 really are the sweet spot for most guns but I’ve started upping my compact to 25 grains to see how far I can touch some pigeons.

I have a mk2 myself that's been up graded to the power block/PP. I like that I can buy any part that I need to repair it where any of my my Asian rifles I can't.
