Front Sight --- Pinpoint Nerf N1 Blaster --- Iron Sights

Front Sight for the Nerf N1 Pinpoint

So that you can at least hit something somewhat if you decide to aim throug the “scope”. 

After some trial and error, I think I've found a good height and shape so that you can aim through the fake scope in combination with the front sight and also hit roughly the area where you aim at (most of the time^^. The N1 darts sometimes develop a life of their own regarding their trajectory)

Since the shoulder stock is too short and the fake scope sits too far back, you should hold the blaster in front of you otherwise you can't aim properly through the “scope”. If the stock is resting against your shoulder, it's not really possible. (I shoot it like a pistol or SMG mostly)
 

Some 2mm crafting foam (or similar) to secure the front sight to the rail. 
(put a strip of crafting foam between the rail and the attachments to secure it like shown in the photos. A section of a halved foam dart also works well for this.)

Since I haven't modded my Pinpoint for short darts yet, I can't say whether the height of the front sight is correct for the significantly straighter trajectory of short darts. If someone has built the short dart mod, I'd be interested to know if it's correct or if the front sight needs to be higher for short darts.

The files are already pre-oriented.
