Q:

AirMax P15 .25

Came last night. nice looking little pup is light as advertised. Spits AA 25.4s 796fps Hi, Lo 576 from just adjusting the hammer spring. trigger not bad nothing in the paperwork on what the reg is set at.

Pulled the stock off as i was unscrewing the rear mount bolt i heard something spring loose. nothing fell out lol. inspecting the bolt threads you could tell how far it was screwed in. so i screwed it in to see how far it moved the trigger rod that was what sprung free.

looks to be about 3 or 4 threads sticking through the hole hitting the trigger rod. i put it back together and just left out the rear bolt the front bolt holds it fine for now. i’ll cut a washer for it later. the side lever started out a little rough. the arm link seems to be hitting a square corner left over from milling i’ll hit that with a file later. not really crazy about the 11mm scope rail but looks like skilled laborer could whip up a weaver rail in no time. on sound at 1 meter away 796fps on my cheap sound meter 114dba, 1meter away 576fps 104dba.
ok so instead of making a washer for the rear mounting bolt i went ahead an sawed of 5 threads. that seemed to work best.

CCW raises the pressure but only move it a tiny amount.. a quarter turn is too much.. back the hst right off and wind it in slowly after each reg change to get the max velocity and then back it off half a turn.

Oh well no 900fps Wingman. 360 degrees from the factory setting CCW/CW dropped the velocity. Set it back to the start still shooting like it’s unregulated.

if you’re awake wingman please drop some knowledge on me lol. reg all apart siliconed the cylinder walls. the quarter turn velocity dropped in to 655/660. just wish my Huma reg would show up bout now lol.

hum first adjustment i went CCW dropped to 545 went back CW to where i started. shot 4 seems to be back shooting unregulated got back up to 810. readjusted CW 1/4 turn lol dropped the next 4 shots to 745 end 767. could use some expert regulator advice lol. so does turning the screw down on the washer stack usually increase the muzzle velocity? going to do another quarter turn CW.

turn your reg up a bit to get 900fps.. looks like your hammer spring is too heavy for that low setting

Okie dokie I’ll give it a whirl. And yes it a pretty hefty hammer spring.

Found out over at GTA muzzle threads m12x1.25 not 1/2×20 says threads would be to loose not use ldc with these threads.

On a full fill it started 731 768 796 814 825 830 802 818 I’d reload 713 725 775 808 836 822 822 832 every time I reloaded it always drop and every shot got hotter. Shot it empty last night pulled the reg the washer stack was dry as a bone. So I lightly silicon greased every washer reassembled the reg put the gun back together first shots 814 817 break 15min 825 818 814 821 819 822 break reloading. 10:18 start back 10:35 817 814 815 811 810 811 807 816. Well so far regulator working much better.

Yes, some local flights, all reflexes still there. Finally on vacation, currently out for scuba diving (like flying, but under water 😛 )…
Looks like an interesting little pup you have there. Needs some tuning, some detail work, but looks like you are getting there for her to be a shooter?

Good to hear the reflexes are holding up! Wish I could say the same lol. Never tried scuba!!well you be safe on vacation Papa.
Yes very intresting that’s what I thought to. It’s over priced for what it is my opinion. The regulator and barrel suck. Yesterday when I checked for a choke shoved the pellet horizontally. This morning I pulled it again an after initially pushing the pellet past TP holding the barrel vertically the pellet dropped to the floor. Only other .25 ammo I have are rat sniper hp 31gn now it was tight going in and fairly tight in places plus you could actually see rifling marking on the slug.

For the blackout stock, as you call it, what did you paint it with?
I mean the type of paint, of course…

Dupli-Color Truck Bed coating, Black Textured Finish

Thank you!

Np Papa! Been doing any paragliding lately?

How does it shoot?
.25 barrels are new for the chinese and Im interested to know if they got it right.. is it choked?

Ok found out how to remove the barrel. The barrel is not choked plus after pulling my cleaning rope 4 times. And a half dozen patches it looked like a gravel road with faint tracks of rifling.
After a mag of pellets she pretty clean now. Shooting 1 ragged hole at 15yd

Just checked Walmart.com not seeing any Chinese compressor. Just 5000$ hpa compressors.

the stock is a bit weird shape, not bad not bad at all
in the UK there was a shop was selling it for £300, sold out obviously :8:

is it true that walmart is selling the chinese compressors? the shipping costs issue has been resolved for you plus warranty lucky buggers
