[Set] SAI Tier One (Utility Package) - Black [EM] + Mini Pistol / Carabine Red-Dot Sight - Black [JJ Airsoft]

Good, compact optic, with excellent controls, good glass quality and nice, clearly visible red dot, even has an auto turn off feature that kicks in in about an hour. Not sure how it will hold under rapid fire, as i am yet to take it to the field, but the construction seems sturdy enough.

Had this on a Shark full-auto pistol for a while and it worked fine until one day while shooting the glass just flew off. It wasn't damaged or anything just detached from the frame - managed to put it back with superglue and clean any mess on the glass with acetone, hasn't moved since (over 1000 rounds since then). To be fair, I had dropped it a few times before that, and the full auto blow-back on that pistol is quite violent, maybe on a NBB or at leas a semi-auto GBB it would be fine.
Apart from that it is decently build, and I haven't had any other major issues.
Overall quality is not amazing but not bad either - for the price it is decent.
The buttons are easy to access and it even remembers your brightness setting once you turn it off and back on.
The lowest brightness setting is still too bright, but sadly most red dots are like this.
The protective cap is made from clear plastic and if it is clean you can use the sight without removing it. It has an ear at the back for a string, but it is also a zeroing tool.
Comes with mounting plate for a pistol. Just remember to use the shorter set of screws when mounting it to the plate and the longer ones on the rail mount (comes with two sets). The screw that holds the plate to the pistol needs retightning once in a while. As long as it doesn't get too lose it keeps zero.

I've been holding myself on writing this review before putting some rounds through the gun. At least I "forced" myself to not rush it. I've got this replica at the same time as I got my F1 FIREARMS BSF-19. I won't compare the SAI to the F1, even tho both are EMG branded.

In terms of looks it's up to it's price point, and to be honest, ain't a cheap pistol. It looks and feels great in hand, it offers some nice features such as the raised suppressor sight, flared magwell, injection molded stippling, RMR cutout, threaded barrel. Can't complain in this category, it's a premium looks pistol.
In terms of performance, after 500 rounds through it, can't remember how many with an RMR and how many without this time, for CQB, which is the main purpose of a pistol in airsoft in my opinion, it's fine, fairly accurate, good range.
As with all GBB pistols, once you put a RMR on top, you have to use a stronger gas in order to combat the added weight, so I used Nimrod Black.
In terms of internals, it's 50/50 TM compatible, the trigger unit is TM spec, the bucking and barrel are TM spec, the BBU (Blow Back Unit) is proprietary. So upgrading or sourcing repair parts for this pistol will be a challenge.
Overall, it's a decent pistol that is overly priced in my opinion. But, my only 2 gripes I have with it so far are the trigger that lacks any tactile feedback, it's mushy, silent and the reset feedback is inexistent and the RMR mounting solution. Using adapter plates raises any RMR over the suppressor sight rendering them useless in case battery dies on the optic.

In conclusion, this gun is a great collector's piece but it's overly priced for what it offers, the performance doesn't match the price. I don't say it's a bad replica, far from that, but EMG should try and fix the issues because there's quite some room for improvements

Very very nice replica. Threaded barrel is a bonus. Flared magwell, Works with elite force magazines, Feels very sturdy in the hands, only one star off because it is not tm compatible and will take mostly AW parts internally wise. I’ve upgraded it with a ML bucking and Nineball 6.00 barrel and she is shooting very well. This replica is surprising snappy stock and even has a red dot mount to boot. For the price, it’s a very very nice “Gucci” Glock replica.

Overall:
Build quality: 9/10
Tm compatible: 5/10
Bang for buck: 8/10
Features: 10/10
Longevity: 7/10 (so far so good so take this one with a grain of salt)
