eally, but Stryfes' need to be modded to be good anyway, so the hassle makes that debatable). Some smaller things that comes to mind is the size, as the modulus is larger and has a carrying handle on the upper back of the blaster that makes it's flip-up iron sight useless. The battery door doubles as a handle grip under the blaster, which I thought was cool. It comes with a lot more attachments, which is the key selling point for this toy: the barrel allows for another barrel to be attached and, by itself, does not affect ranges by as much as the Retaliator/Recon barrel; the scope is lense-less but has a cool targeting sight; the foregrip is comfortable; the stock is useful in carrying an extra magazine but is noticeably flimsy and wobbly with enough pressure on the plastic bars; and there is a Demolisher-style 10-dart banana magazine included with the set. Velocity ratings on my ProChrono Digital chronograph are as follows: the average stock velocity is 72 feet per second (FPS); Unmodified but with 3 Tenergy LiFePo4 batteries and a dummy spacer averaged 91 FPS. The best difference between the Stryfe and the Modulus is that testing of the LiFePo4 batteries in a Nerf War suggests the thermistor/ resistors of the Modulus are more tolerant and do not necessarily need to be removed since no-one complained of it overheating during play (like they did with the Stryfe many times before thermistor/resistor and electronic lock removals). However, there is a noticeable spool-up lag when first pressing the rev-trigger and this 1-second delay is something you will have to live with if you decide to use the recommended alkaline batteries. Further good differences the Modulus has over the Stryfe include the fact that it is paint-friendly and the different Modulus' parts come apart easily when the blaster is opened. Check out my pictures below, I hydro-dipped and hand-painted different parts of mine (one gold and black, another a hydrographic with carbon fiber and flames, and a more recent one I mask-painted a classic Cobra, Python Patrol snakeskin pattern). In all honestly, get both the Stryfe and the Modulus kits (there are many different ones now, including the bolt-action slam-fire able Tristrike) that suit your fancy. The accessory parts are all interchangeable with most other Nerf Blasters, namely the Stryfe, Retaliator, Tristrike, even the Ionfire (it's all true, but I'm joking about the Ionfire; don't do that). As an update, I have been using my setup for almost a year now. Still going strong with the 3 AA 3.2V LiFePo4 batteries and an AA sized (Ultracell; a conduit placeholder) spacer. I have also used 2 Lion 3.7V and 2 spacers, and a 3.7V IMR with 2 spacers and both work, but I decided that it is best to use the 2 AA-sized IMRs, because there is less strain on the batteries and they will last longer; so I will be using those IMRs in the future. I use a Nitecore Digicharger D4 battery charger, it works great and I recommend it. Please mod responsibly, as using higher voltage batteries can be damaging to, and shorten the life of the product.

front grip on the alpha trooper, and a recon stock. Sadly it is wobbly, just like the recon, but can hold a clip securely. The modulus has so many other great things... such as a awesome paintjob and a cool skeletal frame (you will think it's cool after you learn to ignore the fact that a ridge digs into your hand). (it reminds me of the first time i picked up an alpha trooper). It will always be my first choice for a nerf war. But, enough said, the modulus is a 10/10!!!!

and entertainment to the kid. This is toy is worth it and sometimes grandpa got to play and make mess with grandkid.
