P90 woes again! It just never ends.... I'm getting intermittent weak shots every now and then, and I really can't pinpoint what it may be. The symptom of my problem is as follows: 1) weak blowback 2) slow rate of fire 3) low muzzle velocity *this can also happen with or without bbs loaded. that is to say that it happens even when dry firing* I already replaced it with a new o-ring for the perfect air seal, and even strengthened the hammer string for more gas! Also, the hop rubber was recently changed out for a TM one. One thing I did observe though is it happens when the

I had the exact issue on my P90. I resolved the problem by doing two things: 1. Rocket valve gets stuck inside the return Spring - sand down the circumference of the rocket valve so it'll move freely inside the spring. OR get a new rocket valve that's compatible with WE systems. 2. Increase hammer Spring strength / preload by stretching the spring by 1cm.

Yup, I have one installed in mine. Have run it for the past few months with very little problem. It is fundamentally the same bolt but just constructed in aluminium, it's weight difference is such that it increases the cycling rate drastically! However, you do get less felt recoil. One thing you have to look out for is the small pin that connects the two-piece nozzle. As the aluminium bolt is only secured from the left hand side, the pin can sometimes protrude from the right causing it to get jam. Make sure you apply some locktite there to prevent this! EDIT: Also, I noticed

Specifically what did you do to the rocket valve and spring to increase the consistency? My P90 seems to be suffering from the same inconsistencies too.
-
I find the P90 to be very ergonomic to hold and shoulder. My eyes line up fairly well with the height of the optic, so I don't have to purposely change my cheek weld either - which is a plus in my books! I personally use a rubber stock pad instead of the original hard plastic one which certainly improves the handling a little bit, but its main purpose is to let me prop the gun up-right against a desk or whatever.

Another issue I want to bring up is especially pertinent to users in warmer climate like myself in HK. The inconsistent power I mentioned a few posts ago was partially due to the rocket valve getting caught inside the spring. This was remedied by bending the spring's circumference so it's less likely to get caught. The other part of the problem is the weak hammer spring that doesn't allow the hammer to strike the valve hard enough. As there are no after market springs at this moment in time, I resorted to pulling the spring with a pair of pliers, and lengthened the entire spring by

Zinc alloy is actually quite malleable, and you're realistically only bending it around 15-20 degrees. There's plenty of give in the pop to bend that angle. The one thing I noticed, though, was the occasional jam INSIDE the magazine caused by the tightened feed lip. What i did was use a small file to remove some material where the metal lever presses against the plastic. 100% feed; no double feed 100% bolt catch

Just want to make a quick follow up on Vasriotaep's video review and some of the workarounds I came up with. 1. Double feeding issue The well known solution to this is to gently file down part no.98 at a steeper angle so that the bb has more space to sit inside the hop up chamber. On top of this, however, I also found that lengthening the spring (part no. 99) by gently pulling it helps to further reduce the chances of a double feed. You may find it difficult to reinstall after pulling the spring, so I advise using sparingly some adhesive to secure the spring to the nub first before a
-
I purposely disable mine as well to prevent the screw from snapping and / or damaging the hop up unit. Yourself?

RA-Tech has released a steel bolt. Does anyone have or will be trying one? My main concern is that the added reciprocating mass will break the cross bar that holds the spring guide and the hop up unit. If only RA-tech would also make these parts in steel I would jump on it in a heartbeat! Please let me know your thoughts!
-
Nice! Did you notice any difference in the trigger pull?
-
Thanks for the info! Is there any fix for this?
-
Does anybody have problem with inconsistent power at the muzzle? Sometimes the bb would shoot normally at 1.3J using .25 bbs, but there's the occasional bb that just drops out the barrel as though there's not enough gas to propel it. Last night, I was at a game and the problem escalated to the point where all my bb's were shooting well below the usual standard. As I investigated more and put several rounds through the chrono to confirm, the whole thing just stopped firing. Upon closer inspection, i discovered that the two-piece nozzle broke where the pin goes through, and as a result i'm n

Hi guys, I have the Z-parts complete trigger group. It's extremely high quality and have used it for multiple games and backyard shooting. Trigger pull also seems to have been improved as I perceive there to requires less actuation force. EDIT: I'm aware that RA-tech have also released steel hammers and sears, but I find the Z-part to be of higher quality and tooling. I particularly like the roller that contacts the bolt on the Z-parts kit. I found that my cycling is smoother and slightly faster as well.

Hi guys, I got the z-parts complete trigger set. Will be installing tomorrow along with an aluminium bolt from YSC. Will update everyone on performance.
