Well here is my mod of the longshot, same thing as other people, but instead of a longshot spring I used the Home Depot spring (same one as the one used for NF spring replacement mods). I cut about 4 loops off of the spring and still it is very hard to cock with one hand (Feel the muscle burn, and no I am not weak).
The other thing that I did different is the barrel, I used the barrel from the the front gun (I removed it as per the Longshot Front Gun Mod) I haven't tested it for ranges (still working on the dart mods) but it works quite well indoors.
I am wondering did you cut the barrel? because I am thinking about doing this, but it looks a little short?.
Thanks!
