Red dot optic shown in images not included.The Alpha CRB is a versatile carbine length rifle that can be used effectively in close quarters battle and wide open outdoor engagements. The Alpha CRB utilizes a 10.5 barrel and 9 free floating, Alpha rail system. The aluminum receivers feature a stamped KRYTAC logo and a dull matte black finish. Additional features include an ambidextrous fire selector and a locking bolt that provides easy access to the KRYTAC rotary hop-up system. The KRYTAC rotary hop-up has 15 adjustment settings and a numbered adjustment wheel for a quick reference point to determine how much hop is needed. The KRYTAC adjustable battery stock features two different battery configurations, nunchuck style batteries can fit in the tubes or a small lithium polymer brick battery can fit at the rear of the stock in front of the buttpad. A third battery option for the Alpha CRB is a stick battery in the buffer tube. The stock also features two QD sling swivel divots as well as a loop for strap type sling attachments. The Alpha CRB features the latest in shooting sports technology and it has the internals to back them up.

Internally, the Alpha CRB features a reinforced 8mm ball bearing gearbox with integrated MOSFET to regulate electronic signals and to protect the trigger contacts. The corners of the gearbox that surround the cylinder feature a smooth radius, as opposed to a 90 angle, to prevent fracture. Also, the gearbox shell features a small window on the left side where lubrication can be applied directly to the gears or piston, this window is also convenient for inspecting the angle of engagement with the gearbox fully assembled. Additional gearbox features include a modular spring guide system that will allow the spring to be changed without completely disassembling the gearbox. The KRYTAC piston is made of a durable, lightweight polymer and features 4 metal teeth, with the 2nd to last tooth absent. The Cylinder head is padded with an enlarged rubber bumper to optimize the angle of engagement and to absorb energy form the impact of the piston assembly. The material for the gears have been especially formulated to be very strong, Rockwell test figures on the KRYTAC gears are much higher than industry norms. Turning all of the drive train components is the KRYTAC high torque motor, capable of 30,000 revolutions per minute unloaded.

"Been using it for a couple weeks now and it has been pretty great so far. It was pretty weak out of the box but with a new motor, spring and a couple other small adjustments it's absolutely amazing
by Nigel K. on 08/07/2017
"Item came as expected. I had heard about mag compatibility issues with krytac products from other people in terms of feeding and seating properly before I purchased the product, but trust me, do not like that make you turn away from this product. The high cap it comes with is incredible, full metal, and works very well. No feeding issues on that. However, the mid-caps I had purchased would not sit high enough in the mag well to get a proper seal on the hopup. The solution to this was very quick and easy, I applied a couple layers of aluminum foil tape to the inside of the magwell, nearest to the trigger side, and that fixed things up perfectly. The midcaps now feed perfectly fine.

Full metal (excluding polymer stock and A2 style pistol grip)
Comes with a small rail segment, perfect for attaching a grip
Solid weight to it
A solid platform to begin tech work on and modify to what ever you want
Solid out of the box accuracy (tested with .25's)

Mag compatibility can be annoying sometimes
Low Velocity out of the box, around ~300FPS (however can easily be pumped up to 350 to 400 with a new spring if need be)

"Amazing Gun for the money.

Don't get me wrong, this isnt the $350 trident CRB. But it's a great gun. I opened mine up and went to play the very next day and had a lot of fun with it. Sadly, the gun does not shoot very hard. Chrono'd at 265 FPS /: which isn't very good for outdoor play. But other than that it's super solid. Full Metal construction makes it feel very sturdy and realistic. I used a 9.6v instead of a lipo for the first time in ages and honestly could barely tell a difference. This is by far the best gun (quality wise) for the $250 price range. After I played. I went ahead and did some easy upgrades. Longer tight bore barrel (covered by mock suppressor), Spring, and hop up unit. Shoots around 360-370 fps now. For less than $100 in upgrades and only $255 for the gun itself. This gun is amazing.

Amazing Quality
Very high ROF with a 9.6v
Fast Trigger Response
Built in Mosfet.

Does not shoot hard enough out of the box.
