New AEA 30 cal. Bullpup problems

Jump to latest Follow Reply
I have the aea 30 cal 32-in barrel I've probably shot this about 6 or 7 times probably shot about 200 rounds through it so far the cocking effort is a little hard for me but I can manage it I usually put my thumb behind it and pull the lever I've gotten used to it it seemed to have gotten a little easier but when you order this rifle you can order it with a heavy or light hammer spring that's the only way to get an easier caulking system you can probably order the light hammer spring yes they should have put a side lever on them to make it more manageable what they should do now is come up with the conversion kit to change it to side lever also I am going to tune this gun with the power Wheels to see if I can get more consistency at higher power it shoots higher on my targets and then it goes down moa is not good I start out at around 1150fps 185fpe with 61 grain Nelson's and then it drops on my 18th shot to 844 so my shots on the target are going 6 in higher or lower in that power surge I figure if I can adjust the power wheel to get about 980fps that is 130fpe I think that would get me a lot more shots and keep me on target without so much moa that's the thing about regulated air rifles also what I could do is my last mags when the pressure goes down I can go to a lower weight and stay around that speed so I figure the first two mags 61 grain and then last two mags 50 grain so I'm hoping for that Tuesday around that same speed and see if it keeps me on target without having to adjust for anything maybe a little for different distances I just finished doing adjustments on my aea varmint25 Cal I modified it and now I'm getting over a hundred more FPS and 20 more foot pounds now I'll be working on my 30 cal to get it the way I want it

Woody, you couldn't have bought a harder to cock airgun if you'd been trying to do so. I'm a pretty strong guy, and had to really, REALLY WANT IT to get my .30 AEA Challenger bullpup cocked before I started customizing it. Lowering the power on the power wheel will not reduce the cocking effort, because that only restricts air passage through the port.

The only way to reduce the cocking effort enough to make any difference is to install a weaker hammer spring, whereupon the cocking effort will reduce by roughly as much as the replacement spring is weaker than the stock spring. Moly lubing the hammer, hammer-spring, and bolt will reduce cocking effort a little, but will be more noticeable with a lighter HS.

I've done such de-tuning to other (Korean) maxi-blaster airguns to great effect, and saw a 30" barreled .30 Challenger as the perfect candidate. IT IS, in every way I'd hoped.

So I bought my 32" barreled .30 Challenger specifically to de-tune to more sane power levels and find a bell-curve power-band; rather than shooting over 1200 FPS in stock form, and each shot being lower velocity than the previous (that drives me nuts).

My Challenger now shoots with any airgun at any price. Here are the details-

Having found the bell-curve power-band at my desired power level came at only 120 BAR fill pressure, and the factory recommended charge pressure for the gun being 250-300 BAR, once my Huma regulator arrives (next week) I expect to get at least 25-30 regulated-consistency shots from a 250-300 BAR fill.

You bought an airgunsmith's dream air rifle Woody, but it sounds like you might not be an airgunsmith. Hate to say it, but notwithstanding the modifications I've described, you're not going to enjoy shooting that rifle very much (because you won't be able to cock it more than a few times in a row).

Did you ever install and test the Huma regulator? An update would be interesting and appreciated!
