Skywin Nerf Stryfe Blaster Modification Kit - Compatible with Worker Nerf Toys, Easy DIY Upgrade for Custom Design | Enhance Performance for Nerf Battles & Target Shooting Games

The way the parts were packaged and boxed makes the whole kit feel very special. Everything had good fit and finish with the exception of one screw hole that I kind of had to force cock-eyed. It was one of the holes used to hold one of the smaller side rails onto the plastic fillers/inserts towards the front of the factory body. Keep in mind, most of the parts are 3D-printed, so you'll want to be pretty careful especially when twisting the heat shroud on and off and ESPECIALLY when fastening the screws. I thought I was pretty light on the barrel set screw until I looked in the barrel and found a nice dimple sticking out. Luckily, it receded when I backed off. For me, the barrel shroud twists easily enough, but pulling it off the Nerf barrel takes quite a bit of force. I thought about WD-40'ing it but decided I won't be disassembling it much and left it as-is. The flash hider slides easily on the barrel; there are some model-car type stickers included that you soak in water, peel, and stick to the barrel to make up some width to make a solid connection (my best guess!). I tried this and the flash hider just pushed the sticker and broke it into visible chunks out the end. I removed it all and ended up using scotch tape around half the barrel circumference for the final fit.The finished product is the size of a real AR15 just FYI so it's going to be a bit unwieldy for small kids.The instructions are semi-useful until I got about halfway down where the parts were no longer discernable in the diagrams. There is a fancy molded part from one of the smaller boxes that needs to go on the gun before Step 1. I had to consult Youtube videos for help; none of them show the assembly for this specific model, but I got the gist from a video featuring a similar M4. The aforementioned part was nowhere in the included instructions, and I was able to pick it out from the video. Quality-wise, the instructions look to be a copy of a copy of a copy of a fax with no written instructions.My grandson was really looking forward to this kit fir his birthday. However the nerf stryfe gun shown with mod kit is no longer available & the top rail won’t work with the newer modulus stryfe as shown in directions. Disappointing. The kit seems well made & instructions are written pretty well.Edit: we were able to get the kit to work although not exactly like they showed. However, like other customers, we are missing parts. The eye sights weren’t included with our kit.The two scopes shown on the picture were not included in our package - please sendI like it alot, it fits very well, no issues with installation.Was missing the main part.My 10 year old is obsessed with realistic and Nerf guns. He LOVED this kit. He has used the parts on every Nerf gun in the house, parts fit them all.
