King Arms extends the family of M4 Ultra Grade II replicas with new models - M4 Striker. These replicas come in two lengths: as a Carbine with a 380 mm barrel and as a CQB variant with a 270 mm long barrel. There are two types of fronts that are independent of the barrel used. One in the Keymod standard, the other in the more popular M-LOK standard. There are also different color versions to choose from. The Carbine is available in black or tan, and the CQB variant in black, tan or grey (gun metal grey). In total, there are 10 versions to choose from.
The entire Ultra Grade series is made mostly of polymers. King Arms says it's because of the desire to reduce weight. Well ... well. Both front versions are also made of Striker nylon. And since we are talking about the fronts... Most budget, sorry, lightweight replicas are characterized by a certain looseness, i.e. the front and barrel work sideways. The stronger your supportive hand is, the more noticeable it becomes. King Arms solved this problem definitively by designing both variants of the Striker fronts: Keymod and M-LOK. In both cases, we are dealing with a uniform long rail which is a fixed and immovable part of the front, probably, slid from the front on the top rail of the upper receiver. I am writing "probably" because I do not see the front being fixed to the replica in any other way, but I haven't seen any of the replicas firsthand, therefore I can not be sure.
In any case, this solution guarantees much higher stiffness of the design, although it is not extraordinary in itself. A similar solution on the airsoft market was applied by Tokyo Marui in the "plastic" M4 S-System. The only difference is that the long front rail is connected with the upper receiver from the side, with bolts, a design similar to optical sights mounts. The same was done in late Chinese S-System clones.
Other attributes of M4 Striker:
- V2 gearbox with 7 mm bearings and a "quick spring change" system;
- factory installed MOSFET;
- inner barrel with a diameter of 6.05 mm (made of brass);
- enlarged magazine release button.
The "reduced mass" of carbines is 2220 to 2665 g depending on the version (without a magazine).
Muzzle velocity: 340-370 fps.
In the set with the replica we get a mid-cap magazine holding 140 BBs.
King Arms is promoting the Striker series quite intensively. Below is a video announcing the series, that was released in May:
Pay attention to what you can see at the 0:16 of the video:
Yeah ... It's really such a magazine. However, this is not yet another version of the Striker in the style of an AR-47 but only a smart magazine design made by King Arms:
Looks like a magazine for an AK, but in the upper part has the shape of the magazine for an AR-15 and fits all ARs:
The magazines are made of plastic. Capacity - 100 BBs. They have available for some time. They are sold in sets of 5 and cost about 70 USD to a single set.
