Setting mini on low psi for efficiency

Hey guys! I purchased a barrel to let me also play airsoft with my mini and was wondering if it'd be ok to run it at a lower then normal operating pressure say below ~100psi for max efficiency? As is it is a gas hog right now and the event im going to this weekend charges per fill. I dont even need the bolt to cycle, just have enough air going into the barrel to push the BBs. Would just turning down the velocity have the same effect?

The bolt needs to cycle to let air down the barrel. You can try around 150 psi and turn the back cap in really far

I was playing with it the other weekend and when I cleaned it I somehow managed to put the bolt in wrong so that it didnt move and was stuck forward, only realizing my mistake when I went to switch to paintball and low and behold no paintballs were coming out but for shooting airsoft bb's it worked just fine like that.

If you under bore, it will help efficiency as well.

Actually, you're right. You could run the gun without the bolt spring in. The bolt would stay forward and just the poppet would open and close.

The poppet wouldn't fully cycle; it needs the back pressure "pop" to open correctly.

Put pic of your setup on here. I'm curious what it looks like.

I'm suspicious of this story....100% lol. The bolt needs to cycle for the gun to fire properly AND.....with airsoft BBS being so small any barrel attached to the gun would be too small (bore too small)for the bolt to cycle through. Not to mention the feeding of the BBS down the feed neck and the logistical problems that creates.

Never happened.

It's probably one of those systems that threads on like a barrel and has an integrated loading system and just needs a burst of air to shoot.

Edit: as for the back pressure needed to pop open the valve, if the airsoft system threads on like a barrel with a 6mm inner bore, you should have enough back pressure to open the valve. It's almost like shooting with a solid barrel attached.
