"I have 3 Umbrella Armory m4s... An Ocaw 2018, a Krytac LVOA-S 400fps, and the EMG class 3 UA.The EMG
Is build solid and is more reliable than the others. Consistent - Accuracy - durability - and light as a feather. My cousin has the same gun has had the same positive results... It's my oldest UA and has given me less problems than both the LVOA -s and Ocaw carbine 400fps hands down. Note: the krytac shoots about 15 fps faster than the EMG but is much heavier: Hope this helps. God Speed Airsofters

"I like this rifle. This has been a phenomenal purchase with minor inconveniences. To any prospective buyer you should definitely consider buying this if you meet the following 2 conditions.
1. You have the money.
2. You don't have the time/skill or know anyone with the time/skill to upgrade your own gun.

Here is my personal experience and opinion after 4 full sessions of use:
The first thing I noticed when I unboxed this rifle was how light it is. Other guns I have would fatigue me after a few hours but this umbrella gun was very easy to handle and the small rail was small enough for me to wrap my hand over most of it.

When I started testing it and getting the hop up and sight adjusted I was happy to see that my angel custom flash mag drum could feed in semi auto. Full auto was super fast, however it could not feed consistently. Since it came with the Gate Titan mosfet and accessories I was able to adjust the RoF to 70% and set a 5rd burst. RoF was measured at about 1,500 rpm - 25 rps which is still respectable and the 5rd burst was useful for longer ranges without wasting BB's.

With the RoF dialed in I continued to adjust hop up and sights and I couldn't believe how good the accuracy was. Without wind (and detailed measurements) I felt that at max range before major drop off I could hit a man sized target easily and start going for headshots. I would even estimate that at least 3/5 could hit a head sized target at roughly 200 feet. (I use .3 HPA BB's) Again, I haven't measured anything with any detail and this is my subjective experience. I do know that there is one part of the field I play at that is about 270ft according to google maps and I have hit people at that range before. I needed to aim high and they had to be standing still for a good 1.5-2 seconds but I could put on the pressure which I thought was pretty impressive.

As far as FPS goes I got 390 with .2's out of the box and with .3's I was getting 325 and most shots were 1 fps above and below with a max deviation of 3 either way. I just tested it after 5 weeks of ownership (this past weekend was rain so I didn't want to use it then) and with .3s it fell to 318 fps with most shots being within 1 up and down and max deviation still being within 3 fps either way.

When I first started using this gun on the field I only had a non magnified holo sight and that was ok but since the range of the gun was so good I lost track of BB's way before it hit the max range. I went through various optics and I have settled on a 1-6x rifle scope which I feel perfectly compliments this particular gun because the sight is just as flexible as the platform it was on.

If I was fighting up close the 1x option had great FoV and for long range I could crank up the zoom to 4x or above if needed to see precisely what the BB's were doing and account for wind or elevation. Long range engagements were a breeze with the 5 round burst. It was like having a small shotgun and coupled with my 1,500 round drum mag I barely had to worry about running out of ammo. The only problem of course is wind since the muzzle energy isn't that high but I still found it perfectly usable since I can fire multiple shots and compensate for variable winds.

A small detail I noticed was the fire selector switch. Since I go back and for between semi and full auto I came to appreciate how good it was. It was easy to adjust but not so easy that I would hit it accidentally. Also, I love the low battery warning feature of the mosfet. It has prevented me from running out of juice mid game.

My opinion of the product is that it is much more capable than I am and I can't wait until I can make the most out of it. I didn't rate it five stars because the second day I fielded the gun the magazine catch broke and my drum mag stopped working. It broke around the area where the ambidextrous lever portion on the left met the magazine catch. Considering how new it was I am disappointed that such an important piece failed so fast. Luckily it was an easy fix and I was able to repair the magazine as well but it did leave a sour taste in my mouth that day.

I hope this review helps you to decide on whether or not you purchase this product.

Maybe I got a bad mag catch and having a 1,500 drum mag loaded with .3s was a little too much. Maybe I fell down or bumped something that made matters worse. I will not know for sure but other than that one massive failure and little annoyances such as no sling point integrated to the rail and no ability to close the dust cover, I have been happy with my purchase. I would also like to note that the description at the time says it comes with 5 mags. It only came with 2 mid caps. I believe they are PTS EPM mags.
