Walmart exclusive, competitor to the Nerf Rapidstrike. Most people will undoubtedly compare this to Nerf/ Hasbro's famed Rapidstrike blaster, and with the automatic fire, it is easy to see why. The Hyperfire has cool design cues reminiscent of some fantasy video games and real life firearms. Most kids should find this easy to hold, I would imagine, because the thumb hole handle grip is on the small side, but adults with large hands may find it awkward and uncomfortable, a con. The acceleration trigger is conveniently placed directly behind the magazine trigger, a plus. The blaster is heavier but at least somewhat balanced due to the 4 D batteries (not included) being located in the back of the blaster in the shoulder stock area, which has a nice cheek-rest. Looking at the only tactical rail on the blaster, it is apparent that the attachment point is small and almost guarantees that you will need to take off the attachment before you can fix a jam because it is so close to the jam door. If it is of any concern, there are several sling mounts on the blaster. The Hyperfire is compatible with any standard-sized Nerf Elite Darts (blue, green, white, orange, and decorated Rebelle darts) and magazine/drum-fed Nerf "clip system" darts. The Hyperfire boasts the highest Dart Per Second (DPS) rating of 5. That means for every second at peak rev, you shot 5 darts, and that also means that you have pretty much emptied your entire 25 dart drum by the time it takes the average person to finish reading to the end of this sentence. I have tested this blaster, and yes, is fit's Drac's (a Nerf blaster guru) pre-release description of it being a "dart-hose." But how does it achieve this? My examination of the dart-feeding mechanism yields that it is a conveyor belt under the jam door. Literally, it is IN the jam access door. This suggests that as the belt turns, short tabs on the belt snag the darts and push them towards the flywheels. Upon contact with the flywheels the dart is propelled, which Bobololo (another Nerf blaster Guru) has indicated that the Hyperfire makes use of canted (angle) flywheels, which uses slightly off-angle flywheels to put a spin on the darts. This spin is perfect for the stock setup, but for modders who want to use higher voltage/amperage batteries it may be a challenge. There are several reasons why modding this blaster will not be easy, but I will keep things simple with 3 of the more prominent reasons: 1.) the conveyor belt design feeding mechanism is ineffective at a higher speed RPM (rotations per minute) than what it was designed to operate at and may also need extensions on it's tiny tab arms or "nubs" that only scrape at the top of the base of the darts. Also, it will eventually need to be replaced (it is made of mortal rubber after all, and time will inevitably cause it to become brittle and break) and the availability of replacement parts will be doubtful unless there is an aftermarket company that will be willing to make them. 2.) the canted flywheels spin the dart and the Elite Nerf dart design tends to spin out of control at higher RPM, interrupting the stability of flight, resulting in inaccurate and shorter distances. 3.) the internals have surprisingly little to no space to do anything in the more important places (like the acceleration/rev trigger) despite being a bulky blaster with a lot of space in unimportant areas (like the lower front grip). Finally, like Coop (yet another Nerf blaster guru), I have a ProChrono Digital chronograph which I used to measure the dart velocity of each shot. The average Feet Per Second (FPS) of the Hyperfire's shots at peak rev was 72 FPS. The FPS of each dart at maximum DPS would naturally be weaker, that is, in the mid 60 FPS range. Now with a pair of LiPo AA batteries, a pair of dummy spacers, and 4 AA to D Battery adapters I had laying around, I found that the average FPS jumped to 80 FPS at peak rev without any other modifications. All 3 of the aforementioned Nerf gurus have warned of potential jamming issues with the use of old or misshapen darts because of the short nubs on the conveyor-belt feeding mechanism missing the scrawny or thinner dart as a result of being stepped on or overused. From my personal experience, the blaster had not jammed using several different aftermarket darts of varying conditions, but the Hyperfire did stumble a few times during the chronograph testing. In conclusion, I think the Hyperfire lives up to it's Hype, and is a great candidate for Walmart's best exclusive to date. Time and durability will be the ultimate judge of this though, and I will try to update my review if I encounter any problems that I may feel will change my generous 5-star rating.
