Nerf Longshot

I'm currently working on my Longshot and I would like to discuss any longshot type of mods available, currently mine is lacking an air restrictor, but i will replace the spring as well as catch spring and maybe add in some brass and a shotgun mod, thoughts?

As soon as links are enabled, I will have a bounty of information regarding LS modifications

excellent, i will definitely look into the link setup

Try this website. It's a pretty good mod for the longshot. Detailed instructions also. I'll be doing this to my longshot when I get one.

I would suggest taking out all internal locks. They are useless and don't allow for depriming, which would be a very nice step for later down the road when larger/more powerful spring additions are done. Also, I would highly recommend reinforcing the bolt sled. There are few methods for it.

Or instead of sheet metal, I've seen a redbull can's metal used

Brass breeches can be quite a bitch sometimes. SGNerf did a great tutorial for a stock brass breech. modworks.blogspot.com/2010/03/nerf-longshot-brass-breech-mod-guide.html
Be careful and take your time doing measurements, cuts, and epoxying. Test fit things along the way so you know it will work when you put it together.

As for the shotgun grip, I know that pSYk and his friend are selling some, but they are expensive.

SGNerf, once again, has a great mod tutorial for a grip: modworks.blogspot.com/2010/05/nerf-longshot-mod-shotgun-grip.html
If you're looking for a grip on the cheap that still looks great.

And for more mods
