Ok this gun shoot nice and sound nice, if you want it to look cooler put fake suppressor on it, *tsh* since it matches the sound. Had to drill and really twist the crap out of the orangle muzzle flash hider 🤬also wealized left is tighty, right is loosey, and love the sound when you bolt press, sounds real. (Like two chains pulled opposite directions) 🔗

It also has nice little kick, real rifles dont have much kick so theyre both almost the same

Alot of people talk about leaks, I havent really had what they had, but make sure not to put gas and hold it without taking it off be ause the mag will freeze and leak everywhere. Instead just press it for like 1 or 2 second at a time...
Only bad thing is mags are kind of 💸💸
ALSO GET GBB SPEEDLOADERS THIS GUN ANNOYING TO LOAD WITH HANDS!!

This gun is good for beginners LIKE ME, and pretty realistic for 210 bucks, i used SUMMER2023 code so it went to 187.

"So I was skeptical and shot on a review for awhile; but after having some more expensive GBBRs with worse results this is really a great deal!

I had the M4A1 model; lasted about a year before I really had issues; needed a new nozzle and bolt; simply due to wear but it got it backup and running!

I wish the accuracy was a bit better; also I “lost” two magazines that simply developed leaks and I couldn’t save (past warranty so attempted to fix with RTV silicone) so be prepared to maybe dish out for new mags at some point; but the magazines that have been good from the start have stayed good.

If you don’t want to spend your life on a GBBR, this is the way to go; you can spend $600, but keep in mind all green gas still has the same limitations; I live in the northeast and ever GBBR I have struggles with gas efficiency and cold weather; magazines sell out quick, if you just want to see if GBBRs are for you, start here!

"I bought the "Matrix M4 GBB AR-15 Gas Blowback Airsoft Rifle w/ Reinforced WA System (Model: Slim MLOK 15")" model back in September 2022 when it was on sale, it was my first GBBR (I've had many GBBP - pistols WE Tech) and was nervous that it was so cheap on sale, it is all reinforced Polymer and made in China (not Japan or Taiwan).
It uses the Western Arms Gas System and hence any "WA" compatible Magazine. The Polymer Castings are Top Notch Quality, the Upper and Lower fit VERY Tight, No Wiggle at all, and the great MLOK forearm is Aluminum and fits tight, although the factory installed it a bit crooked which is easy to adjust.
Pros:
- It's a gorgeous Full Length M4A2 rifle, it looks metal, realistic weight and feel.
- Upper and Lower fit Tight, Metal Buffer Tube, Metal Bolt and Charger.
- GBB Mags fit snug, trigger pull is excellent no "step", moderate weight pull.
- 14mm CCW Threaded Barrel Muzzle, minimal free-float barrel movement.
- 380 to 400fps w/.30 BBs, consistent 2" groups at 150ft in S.A. Fire.
- OK Iron sights, good quality "Fat" K Butt Stock", Flat Trigger guard (replace that!)
- "WA" system GBB 50rd Mags are cheaper than WE or T Marui types & never fail +!
Cons:
- Sloppy factory install of MLOK forearm, easy to readjust, though.
- Virtually NO lubrication internally, especially the Bolt which "hung" out of the box.
- Some of the Polymer casting seams are sharp, you'll have to sandpaper them flat.
- Black paint already wearing off Selector and Charger after just 1 month of use.

Summary: I immediately built up mine as a Replica M4 Mk12 DMR use, it's that Accurate and Powerful. I run mine with a 190mm Silencer Can I design and other than the blowback mech sound, you don't hear this GBBR! I've used it on 12 outdoors MilSim Game Plays with Zero problemo's. It also makes a great Infantry Rifle too. This was my first GBBR, and I'll unlikely buy another AEG now unless it's a Machine Gun. I'm already planning on buying one of these JG Works made Golden Eagle /Matrix BGGR in a M4A3 Carbine length now ..... as soon as Evike or someone has them on sale again! (Hint Evike.com)
