Dynamic Precision Aluminum Loading Nozzle for Airsoft GBB Pistols
(Type: SAI BLU)

"works great, nothing else to say dropped in my WE gen5 glock 17

"This loading nozzle is borderline dream material. It breaks in nicely and tolerates Nevada desert gaming heat which hits 100+ F and turns green gas into beastjuice (possibly unstable). I have to use .32s in order for minimal hop up not to overhop during these conditions.

Keep an eye on the rocket valve set screw on the top of the nozzle, if you can find an o-ring that small it would be best, maybe some type of rubbery adhesive, because it will vibrate loose with time. I just keep an eye on mine from game to game.

You will also want to pair this with an enhanced loading nozzle spring, to cover the pre break-in friction.

"got this for my tm g17 and it has been good, the uac bbu v2 works OK with it as the airseal is meh, wish they used the guns modify design so i could put a nineball piston head on there.. anyways

Pros,

-Extremely robust, will probably last 2-3x longer than and average 3rd party nozzle
-Slight increase in FPS over stock nozzle,
-nice exterior finish to conpensate for any scratches/abrasion from bbu

Cons

-Dosent come with rocket valve and rocket valve housing, which is another 20+ if u want the UAC ones, which is a bit steep considering this is $70 on evike
-Stock Valve housing/rocket valve as well Guarder dont fit well in the UAC nozzle, but the guarder rocket valve works fine in here
-Since the inside of the nozzle is POLISHED it would be very hard to fix if there were a serious scratch from inside the bbu(which is possible as they dont have the extruding tabs towards the bottom of the rear to keep the tolearnce tight in the bbu; i think this is done as the aluminium on aluminium would have to high of a friction coefficient with that tolerance for the gun to work smothely.) Scracting will mostly likely only occur from the UAC BBU cause of the burrs from the slots that house the o-ring which can be avoided if sanded down(OVER ALL I SEE THIS BEING A MINOR AREA OF CONCERN)

All in all this is a very nice nozzle. If you are looking for the utmost "reliability" and money isn't an issue then get this nozzle.

Otherwise I would suggest getting a couple Guarder/Gunsmodify nozzles if you are on a budget
