"The gun has a lot of kick and is quite accurate, but the fps is much higher than 430, it can shoot 485 with a 20 gram bb on an 80 degree day, which is way too hot for most fields. If you do decide to buy, you can only use the HIGHEST quality bbs, I used elite force .28s, anything lower quality will be smashed to bits in the gun, and cause a host of problems. If you do want to buy it and use it on the field, you have to be willing to spend an extra $200 for a lower fps bolt on top of the gun, to make it field legal. To play with this gun, you need to be willing to spend about $600. It is not very practical for day to day gameplay on fields. Short of that, it is awesome internally and externally, and has a ton of kick.

"I bought this on black Friday so I got this cheaper than $420 and I must say this is the best gbbr so far, whether you shoot this on burst or full, its just so efficient on the gas even more so on semi and its smooth too as the bolt cycles. The look and the feel on the gun is very high quality and has some weight to it as well. I highly recommend this! Yes its expensive but its worth every penny.

"When I found out that this beautiful airsoft gun had finally been released, I made it my mission to get a part-time job in order to afford it. And I have to say, all those hours of hard work had finally paid off, and it is worth it! I've owned this airsoft gun for over two weeks now and got to learn more about it, along with things that I like and don't like about it by handling it firsthand.

The hand guard, lower receiver, and stock are made of polymer, but don't let that discourage you, it is actually very high quality polymer, it may even be military grade polymer, I am not sure, but it is very durable, and also helps keep the weight down. And in some cases I would prefer this over metal, which can dent and get brittle in very cold temperatures (which I will talk about in a moment). However, I would have liked to see some metal reinforced parts to increase reliability, like for example on the folding stock, I would have liked the latch and catch to be metal, cause I do fear these parts may break if I am too careless. Other than that, the polymer body is very solid.

The PTS Masada GBBR functions very much like it's real-steel counterpart, with its host of ambidextrous features like , the magazine release, bolt release, fire selector ( which is a bit too stiff for my taste, but loosens up a little after awhile, although it's good to know it won't go into full auto by accident), and the charging handle ( which in a sense it is technically ambidextrous meaning you would swap the charging handle to whichever side you prefer). Other functions include being able to power stroke, the quick change barrel system, and disassembling the gun is very much like the real-steel version. So if you are looking for an airsoft gun that simulates it's real-steel counterpart, the PTS Masada GBBR has got you covered.

Going back to what I said about metal being able to get brittle under cold temperatures and breaking. The front flip-up sight is made of metal, and unfortunately it did break on me after flipping it a few times, but it is my fault since I left it in my car over night in the cold. Fortunately, I contacted PTS Syndicate by email, and they were very willing to help send a replacement part as long as I paid for the shipping, which I had no problem with. But my advice to avoid this is to just be gentle with the front flip-up sight, and don't leave it out in the cold for too long.

Very durable body
Functions and simulates the real-steel Masada ACR
Recoil feels amazing, and very satisfying to shoot
Very solid stock, much more solid than the SCAR stock
Easy to adjust hop-up
Has KWA internals, which are very famously known for being gas efficient and very reliable
Very accurate once you get the sights zeroed in, you should easily hit a target the size of someone's head from 20 yards away
Good customer service from PTS

Stiff fire selector (but simulates real-steel Masada)
Front flip-up sight can be easily broken (be careful)
Would have liked to see some areas be reinforced with strong metal, to increase durability and reliability
Front heavy (does not bother me too much since the real-steel is actually front heavy itself, so this is a accurate simulation of it, but for others it might be a problem and cause fatigue

So do I recommend this gun? Yes, I highly recommend it. If this gun is within your price range, you're able to afford at least four extra mags, and if you're like me and love airsoft, and like to simulate the feel and realism in your airsoft experience, this gun is perfect for you, and you will definitely stand out from all the other M4 users, so be prepared to be asked by a bunch of people to tryout your gun. If you are just a beginner airsoft player, I wouldn't recommend getting a Gas Blowback Rifle as your first gun, although when I first started playing, my first gun that I got is a GBBR, but I did have people around me to teach me how to use and maintain it. So if you are just starting and you're up for the challenge, go right ahead. GBBRs are a lot of fun to shoot, and the PTS Masada GBBR is no shortage of that.
