M1887 custom nerf shells

thingiverse

Created a selection of custom shells for the M1887 blaster that fires 3/4 length nerf darts as standard. Ranger5 - This is similar to the original shells that came with the blaster, but with snug dart fit for its whole length to up the performance slightly. If you're printer settings are spot on the internal bore will be 12.7mm, which I've found to work the best for most darts. Brass5 - Similar to Ranger5, but designed to have a length of 17/32 brass fitted once printed. This will slightly improve performance further. Ranger6 - A shortened version of Ranger5 that's designed to give you six round capacity in the magazine, over the stock 5. It is designed for half darts only. Brass6 - Similar to Ranger6, but designed to have a length of 17/32 brass fitted once printed. This will slightly improve performance further. Again this is for half darts only. Ranger6spacer - This is a spacer that needs to be inserted into the breech and carefully pushed into place with one of the shorter shells. The spacer is inserted barrel first and nests inside the barrel/breach portion and gives the shorts shells the correct surface to butt up to so that they can be used. You need to fit an O-ring in one of the groves to stop the spacer sliding out of place in the breech. The spacer also compensates for the shorter shells having issues with air being wasted due to the short length, which otherwise has a drop in performance. The barrel portion of the spacer is approximately that of 9/16 brass and gets the half dart performance back up to be similar to the longer darts. In my experience of testing, I wouldn't recommend using Worker half darts at all in this setup as they seemed to be massively unstable. Those darts are better for more highly powered blasters and really need a good length of barrel to stabilize them and in stock for the M1887 just doesn't have the power to do that job. Best to either use cut down streamline darts, or normal waffle tipped half darts. Please use responsibly and we assume no responsibility or liability for any personal injury or damage to the blaster
