The Type 96 and APS2 are different barrel designs. The type 96 has a mag catch where the APS2 does not, you will have no way of keeping your mag in the gun. I'm afraid to say it, but I'm rather confident the Aero wont work.

Your inconsistency might be coming from your tightbore, I have heard a lot of issues come from the brass in DB barrels. Get yourself a Prometheus tightbore with a stock TM hopup bucking and you wont go wrong. Trust me, its what I have been using for the passed 3 years.

Lube the outer Oring on the PDI chamber when putting it in, A lot of people get poor results because they assemble the chamber improperly and use hard buckings. Hard buckings will only give you clearance problems.

All the little spring is used for is just a little more boost on your hop, you don't need it, but sometimes It helps when using .43's.

Dutton, is that hole on the hop top an empty thread? because the mag catch for the Type 96 threads into the chamber.

Here are some close shots of what I can get to compare the Aero. Along with how the spring should look on top when inserting it, I don't get why you need tape.

I mentioned the lube on the outer Oring for ease of getting the chamber into the outer barrel.

I have Tsunami BB's right now and they are complete garbage, I don't even want to finish the bag. Get yourself some KSC's, they work great. I have also tried the Orange .43's, they leave quite a nice residue in your chamber, also after you have them in a bag for a while dust forms all inside the bag which clearly is not a good sign.

The PDI outer barrel does not line up properly with the stock receiver, it will be about a quarter or even a half turn off like you have now. Its a nice scheme PDI came up with to make you buy both the receiver and outer barrel.

I have a stock receiver with the PDI outer, my threads aren't as off as I have heard from others but when you get your outer barrel and it doesn't line up properly that is the reason.

Good luck man. Once you are done you will have quite a badass rifle.

Otherwise, My main problem is not getting enough hop. I'm using KSC .3's and I've adjusted the screws out as far as possible.

Thats what the little spring is for, a little extra boost of hop.
