"After 1 year of having this, It still works like i just bought it....
by ADAM L. on 03/02/2016
"I purchased the KWA KM16BR on a recommendation from several friends in the Pacific Northwest airsoft community. After using a bolt sniper (Well MB05) & an M4 (G&G CM16) for around 18 months, I decided it was time to purchase a medium- to long-range AEG. It was also very important that the AEG worked well enough straight out of the box to compete on the field without needing a ton of upgrades. The KWA KM16BR was the result.

Overall, the KWA KM16BR is a high-quality AEG that I expect to last for many years in tough use. The gun is well-made with good components & is easy to upgrade. I definitely recommend it if you are interested in an M16-style AEG that looks raw, shoots around 400+ FPS stock, & its not important for you to have gadgets all over the gun.

This AEG feels very tough & has more weight to it than other AEGs made with polymer handguard & lowers. It is about one meter long making it possibly too large for younger players as well as difficult to handle in CQB (too much FPS for some indoor games anyways). The pistol grip has a nice little bump that sits between the middle & ring fingers to assist with proper handling I feel like my shooting hand glues to this gun! A very nice feature that is accurately modeled from the real steel M16A3 is the removable carry handle. It is easy to switch out different optics depending on what you like to use, but the included sights are definitely good & look rugged. There are two sling mounts integrated into the frame making a two-point sling a great accessory to help carry it in the field or assist with aiming. (I HIGHLY suggest a sling because I always see players exhausted from carrying their guns the whole day.) Aside the short top rail beneath the carry handle, there is no room for other optics or technology. Why not throw a wicked plastic knife on the bayonet lug at the front of the barrel to compensate?

In its stock form, the KM16BR is best suited for 0.25g BBs as 0.20g is too light & 0.28g is too heavy, but I knew this gun would get best results with 0.28s. The stock hop up bucking is a unique two-part unit that has little rubber teeth to hold the BB in place before firing. While this bucking is of good quality & should not be thrown away, it is not strong enough to properly spin 0.28s. I immediately replaced the original bucking with a Maple Leaf flat hop bucking. After putting a few magazines thru this upgraded rubber, it settled in very nicely with a flat shot out to around 150' & solid groupings using 0.28s. Without upgrading the spring it was shooting just above 400 FPS. Excellent!

For a battery, the KM16BR comes LoPo-ready if you like, which is awesome. You can use an 8.4 or 9.6 NiCad as well as 7.4 or 11.1 LiPo without modification it even includes the large-to-small type adapter so you can use large- or small-type batteries right away. The only downside to using the 11.1 LiPo is it will put more wear on the gearbox, but it will shoot super-snappy. I have used a 7.4 LiPo in games & am happy with the results, but am also confident that my 9.6v will be great, too. The battery compartment in the stock is large enough for a two small batteries to fit, or a battery plus a granola bar for the field!

This gun is LOUD. You cant be too stealthy using this beast as anyone nearby will hear you shooting. I believe this is a result of the empty space in the front handguard as well as the large stock. Filling these spaces with some kind of foam will undoubtedly help reduce vibration & make it a little quieter. For those who like it loud, dont change it & youll be happy.

One downside is that some magazines work better than others with this gun. The included KWA mid-cap works flawlessly, whereas my Elite Force M4 mid-caps sometimes worked better than others. The first few shots with the Elite force mags would misfeed, but after getting thru about ten BBs it was perfect. All my hi-caps worked perfectly including G&G and Elite Force. If you can afford to, I suggest buying KWA mags for best results. On a similar note, this gun does NOT include a speed loader.

Something sad: out of the box, my hop up unit required disassembly & maintenance to operate properly. No AEG should require repair when it is first opened & has not been used yet! Having said that, it is also important to understand that any new AEG will need 500-1000 shots plus a barrel cleaning before all parts settle into place & work perfectly. Anyways, my friends were there to help me & it was a minor issue that took fifteen minutes to fix no big deal.

4/5 stars for being picky on mags & needing some fixing before use. I cant wait to get into another game with this thing!

Excellent out-of-the-box performance
Tough build

"A really awesome gun haven't had it in battle again but used it for the first time the put a few rounds down range unbelievable for performance reaches out there really far and hit hard can fit a large 9.6 volt 4000 mili amp hour battery in stock build quality is solid but not too heavy to where you would be fatigue out in the field for a long period of time it is fairly long is the only downside but that's the only negative I could come up with for is the length. That's expected with this type of would definitely recommend for out of the box fun this is the best choice it is very very solid and well built went with this gun because I wanted a standard battle rifle with straight iron sights and no optics at all and also wanted to utilize a large 9.6 volt 4000 - 5000 battery my only negative I find is it does not have factory trademarks from any manufacturer except for the manufacture of the airsoft but that's a very minor minor minor things
