Mini PAC Full Auto

Unread postAuthor: Petitlu » Thu Jan 26, 2012 12:32 pm

When I got up this morning I remembered that I had one pop off and I started to do a mini running in full auto 10bar
I finished this evening, I met some problems for the charger O-ring to avoid sending more balls ...

Chamber also some problems since I welded a bolt 1 / 8 T on a 14mm ...

My wife was baptized the PFA: Pocket Full Auto :D

Sexy :)

As always, the problem is reliable feeding and loading...

By the way, if you modify your QEV and feed from the chamber, as I did here, you will get better performance and less waste:

You can open up the top of the pop-off ( file it off) inside is an adjustment screw.
You could probably get it up to 14 bar.
In combination with a slightly bigger chamber you can get the ROF down..

This will help feeding the ammo and get you more powerful shots.

if you modify your QEV and feed from the chamber


This is something you can do for full auto too.

Small hole on the side of the QEV piston ( with hot needle) and a weak spring behind it will make it much better.

You can just put the safety popoff onto the QEV and feed the chamber directly.

Less wasted air and fewer parts.
Also this will reduce the pilot volume.
Like I did here.

Petitlu!!!!! Ou est-ce que t'as trouvé ta QEV industrielle??? Ca fait des années que j'en cherche une! Je m'étais résolu à fabriquer une QEV maison qui fonctionne a merveille mais... bon, l'appel de la simplicité!


For non French people:

Petit lu!! Where did you get that industrial QEV? i've been looking around for one for several years. I finally chose to make my own and it work like a charm, but hey... call of lazyness...
