"Good starter gun for not cheap/expensive good durable gun/m4 starters.

"This would be another 5 star review if the first one I received worked but anyway after getting it back from evike and using it this is an amazing gun quick trigger response good rate of fire high quality internals It shoots about 380-400 with a .2 out of the box but I'm going to be putting in an m90 spring for cqb better than my $200 gun and other friends guns good job matrix this is a great gun whether you're new or experienced.

"This gun is a great starter weapon for new beginning players that price range around 200$. However, I had problems with the gun as it came in. For example the manual was misleading, the manual tells you one thing wile its a completely different process in order to get the stock off. For veterans it would be easy to install the red dot sight but for new players it may be struggling since their is no manual on how to attach it. Another problem I encountered was the clamps(on the stock), it may be I had bad luck with a faulty unit but the clamps were glued shut to the point were I had to use pliers to rip them off and cause damage to the plastic plus the stock part of the gun itself. Besides these little announces the gun itself preformed great for whats its worth and was very accurate too.

"I bought the RIS 9" variant of the Molon Labe package. I have to say after shooting it a bunch and dialing the hop up in with .32 gram milsim max bbs, this weapon does not disappoint. The micro-switch trigger allows for a very snappy trigger response and with an 11.1v lipo at 20C-40C rating the rate of fire I got was 20-22rps. The weapon is shooting in between 340-375 with a .25g bb and is very accurate even out to 150 feet(5.27 inch group in 9mph wind on an 8inch target) with .32g bbs.

The weapon is not without its cons however. On my model the trigger spring is rubbing along side the gearbox shell a little too hard and causes the trigger pull to be much harder than most would prefer. I solved this by taking regular silicone oil/lube and dropping a few drops into the trigger and spring every so often just to keep it nice and slick. The Stock has an incredibly large battery compartment, but it does wobble left and right a little bit. My package came with a 6mm ProShop midcap, not a BAMF, but no big deal. Another con is that my SportPro micaps, elite force midcaps, elite force hicaps, and my Krytac hicaps do not fit in the magwell right, and they dont lock into the magcatch. I did replace the magcatch to see if it was the problem, but I think the magwell may just be too tight for the mags, as certain STANAG type magazines curve at different angles.

Overall if you love using 6mm proshop mags and valken or g&g hicaps you are good to go for indoor and outdoor play without ever having to open up the gearbox and change anything. Great weapon for the price, as It is more accurate than my brother's Krytac Alpha CRB and hits a tad harder with the same rate of fire.

"In addition to my previous review: Don't try to take this gun apart unless you have replacement springs ready because it does not tide well with being opened

"I have had this since august 2017 and it has been serving me well but I probably wouldn't buy it again because I'm not a fan of the polymer body but was a good starter weapon for any new players

"Is the suppressor detatchable?

"To start: this gun is great for a beginner. Without going into too much detail, I'm just going to give this gun my piece of mind.
For the bad: Pathetic external build quality. G&G makes amazing polymer externals. To label these externals as anything but ABS plastic is a lie. The charging handle design is awful. So much receiver wobble that I only owned this gun for a month before selling it because I couldn't bear the external quiality. There is a 1-2mm gap that runs the entire length of the receiver. Compression parts (cylinder, cylinder head, air nozzle & piston head) do not create a good seal, even with a replacement O-ring. The included motor is not a torque motor. It is a speed motor. I know this for a fact, It couldn't turn over the M120 I received from my matrix full tune up kit, and I could spin the pinion by pressing a sponge to it (it's that weak).
Now for the good: This internally is the Umarex QC spring guide gearbox with the Micro switch trigger, but only 6mm bushings (6mm is ok). You can spam, and I mean, spam semi all day long with this. As fast as you pull the trigger, this gun will cycle. This is in part due to the microswitch trigger, but also the speed motor and light spring. This is also the first GB i shimmed to where the gun was practically silent. It sounded & performed beautifully. This is also an amazing deal. I bought this to learn my way around a version 2 gearbox, and I did just that. You also have everything you need to get right out on the field and have a great time, with a rather impressive looking gun (the included Micro T1).
If it weren't for the poor external build quality of this gun, I would have loved it. Would highly recommend to someone for a first gun/ getting a taste for airsoft & getting away from throwing money in to empty space for rental guns.

"PROS:
-Affordable
-Good for CQB
-Accurate
-Mine came with a vertical fore grip and front/rear flip up iron sights

CONS:
-Plastic Body
-Inner Barrel on mine floats a small amount and could effect accuracy. Was easily fixed with an O-ring however

Not really a pro or con but mine shot a little hot at 375fps with .20g bbs. Ultimately I had to get my spring cut to fit my field's indoor limit though.

"This is a great gun! Out of the box it shoots great. Fantastic internals, material is a nice polymer material that feels amazingly strong.

"The gun has a great rof right out of the box and is fairly accurate. Mine however had a problem and wouldn't switch to semi instantly; I would go from either safety or auto and it would shoot full auto for around 6 rounds and then switch to semi. Besides that its a great gun that has a nice feel to it.
