Savia 7.5" Hi-CAPA Gas Blowback Airsoft Pistol Caliber Carbine

"Got this as my first GBBR. If you're a hi-capa user, this is an excellent choice. You get the benefits of cheap and reliable hi-capa magazines, with the reliable TM MWS system. The construction is solid, all metal, steel bolt. It accepts a wide range of MWS compatible parts. For the price you really can't beat it. It does have some cons, but I feel like at this price point none are deal breakers.

I've already put several thousand bb's through it and only had one malfunction, a broken bb that jammed into the bucking, but I don't blame the gun. I think I accidentally put a sus bb from the table at the field I play at by mistake.

The only major components that are proprietary are the valve knocker, nozzle, and hop unit. I'm sure with some work some aftermarket hop units can work, but I haven't attempted to buy and fit a new one. The stock unit works fine and is easily adjustable through the mag well using a flat head screw driver. It has a positive click engagement.

Out of the box it was shooting 360-370+fps with 0.2g bb's. ROF is around 16-17rps give or take a bit. An npas can be installed, or if you're handy, the stock valve can easily be modified to be an npas valve.

Also, make sure not to overload your hicapa mags. You can fully pack it, then remove 1 BB so the stack can still spring up and down. Otherwise you can expect the nozzle to jam up. This is pretty typical even with hicapas so not really a con, just something to remember.

Gas efficiency is ok. It'll easily go through a full standard hicapa magazine without issue, but will require refilling the gas after (During testing I measured that it uses between 5-7g of GG/Propane per 30 rounds give or take a bit)

All my TM and Golden Eagle mags have worked perfectly, both in fitment and operation.

Bolt has never failed to lock back on an empty mag for me.

Pros:
-Cheap hi-capa magazines
-High compatibility with MWS components
-Nice weight and feel in the hand
-Compact design, great for CQB players or players that want a rifle that's easy to maneuver with.
-QD mount on the hand guard and rear of the reciever
-Ambi bolt release
-Appears to be pretty reliable (time will tell how long everything lasts, but so far it's been excellent)
-Trigger pull sear is adjustable, but does not have a grub screw installed. A proper length 3mm grub screw with a dab of blue loctite can be inserted to adjust the trigger sear.
-Shoots great out of the box with some caveats
-Easy to adjust hop up unit, only requires a flat head screw driver to adjust.


Cons:
-Nozzle head buffer will break. I recommend removing it before use. It doesn't seem to affect the operation. I've had it removed since I got the gun
-Nozzle gas port absolutely shreds Nineball magazine gaskets. This can be remedied by putting a gentle ramp on the front edge of the nozzle ahead of the gas port so it doesn't slam into the gasket and tear it up. Don't touch the area immediately around the gas port. After working it over, it's no longer damaging my nineball gaskets and did not affect performance one bit.
-Nozzle is proprietary due to using hicapa magazines, but replacements are available.
-Mag release and bolt release on the right side are plastic, but I'm not worried about them breaking.
-Grip and stock are meh, but at this price point are to be expected. They're easily replaced with standard MWS compatible parts
-Stock bucking will massively overhop 0.2g bb's, I suspect it will over hop slightly heavier bb's as well. But it's an MWS compatible part, so drop in your favorite MWS compatible bucking and send it.
-This gun ships with a CO2 mag. it's an ultralight mag, but as I don't use CO2 and don't recommend using CO2 i can't really comment on its performance or reliability.
-No mag release on the left side. Not a major con, but I know some people may prefer having an ambi mag release.

Overall I feel like this is a great PCC. Utilizing hicapa magazines opens the door to a lot of people that are more budget minded like I am and are already hi-capa owners and don't want to break the bank buying gbbr magazines. The combination of hi-capa magazines and mws compatibility made this purchase a no brainer for me.
