Just in time :D I needed a new hopup unit!

I just hope the O-ring isn't fat enough to start causing feeding problems for weak magazine springs.

I have a suspicion that the ring is out of the way when a magazine is inserted, and somehow only "pinches down" when the mag is removed.

The LED is interesting. But I wonder if the unit will be compatible with the Ajax STS.

It looks like simply two slots cut into the side of the feed tube...the bbs feeding up would have to overcome the o-ring tension to make it up. Weak springs would likely blank fire. I'm sure they'd work with a Hicap.

Looks like a better moustrap...sure it works...but is it necessary at all?

If you drop your mag...how do you clear your gun? Invert it and shoot out what's left?

Thats what I was thinking about. If you have to go to all clear, heading into the safe zone. I don't want to have to eject the mag then invert the gun and fire it off a few times until I know its empty. 3-4 BBs is not worth my money one bit. I would take the oring out. I just like the adjustment wheel and tracer functions. The o-ring seems pointless.

It's worth it when you're using real caps indoors, and need to do tac reloads.

And if you want to clear it, can't you just tug on the o-ring to drop out the leftovers?

What about the one round in the chamber. Im not talking about the 3 in the feeding tube of the hopup. but the one chambered into the hopup with the nozzel holding it in.

Either way, oring or not, you still have to clear it. If that means having to fire upsidedown three times, id rather than then get a BB in my eye when my goggles are off.

Obviously, but I was just referring to the BBs held in the feed tube by the o-ring.

Pop the o-ring off to drop out the 3-4 BBs, pop it back on and fire it a couple of time to clear the chamber.

But those 3-4 BBs is a very significant amount when you only have 30. This would work pretty well with the real caps that have an extended follower so that they feed every last round.

The o-ring is on the inside of the feeding tube on the hop up unit. Not easily accessible, and not at all with hands. You would need a small probe or hex key to pull it.

Now that you mention the slots I feel completely in control of my understanding of the unknown design!

I bet that when the mag is inserted the feed tube is pinched together slightly. If the slots and o-ring are matched appropriately then there should be no o-ring in the way.

When the mag is not present the feed tube is not pinched together and the o-ring (well, the parts showing through the slots) retain the BBs.

No more 3-4 BBs dropping out the hop-up when you pull out a mag would be nice.

Unless I misunderstand you, this is really the only safe way to clear an AEG anyway.

Regardless of the BBs dropping from the feed tube when mag is removed, in my experience there's almost always one left in there. Drop the mag, invert the gun, pull the trigger a few times = cleared.

Since I can't edit or attach images in my previous post:

The proportions are off but I'm sure you get the idea.

Obviously, I certainly did not fully explain what I meant regarding clearing an AEG.

Yes...of course, when you're done, the mag should be removed and the AEG should be fired semi (in a safe direction) until you get 3-4 blank shots.

Maybe I've just seen too many broken guns...but I've seen more than a few that worked fine with a mag, but inverted and with bbs just sitting there, I've seen plenty that don't feed the bbs unless there's a bit of pressure (even light pressure from a finger tip).

Anyways...I don't much care for the idea, I think it's silly to worry about 3 bbs dropping out when you've just shot thousands of them all over the place.

when I get my hands on one, I'll just use it for the tracer feature. removing the oring should be sufficient to allow the BB's to fall out as usual.

I have some of these on the way with my next stock order. I will do a Youtube review for sure!
