I'm doing a simple spring replacement (#49) and barrel replacement (1/2" PVC) mod on my NF. The problem is, the #49 spring is so strong that epoxy alone will not hold the assembly together. What I mean is, when the gun fires things tend to pop off/out of place. I have looked through many threads for an answer and I have learned plumber's goop or caulk may work well to hold everything together. I'm sure someone has had the same problem as me and I am wondering if someone knows a solution.

Did you cut down the spring? I've been having a problem with my DiskShot and an ACE #49 spring. Im thinking cutting it down will work, but the problem is, it wont stay cocked. I've replaces the catch spring and everything.

Goop. Epoxy gets rock solid, prone to snapping apart, whereas goop always remains slightly elastic, and it'll contort just right with the extra punch.

You are using pieces 1, 2 and the AR backplate right? You need to roughen the surfaces of every place the epoxy goes and make sure there is none of the lube on it either.

This is what I do and I've not had problems like yours with the many NFs I've modded with #49 springs.

- No, I did not cut down my spring

- Goop seems like a good solution

- I'm only using 1 and 2. The PVC I'm using doesn't allow me to use any more than that. It's for micros.

Trust me, goop the shit out of this thing, and maybe add some hot glue reinforcement inside. Keep in mind if you go all out with goop and hot glue, this gun is probably staying closed forever haha

Try roughing the plastic before epoxying. Also when exposing make sure to use tape or something to secure it up. Bungees might be good here. Don't touch it or anything until the approved dry time on it.

A note on the gun not staying cocked: what I sometimes like to do is take a long-bladed xacto knife and cut the catch on the rod a little deeper so its sure to stay cocked.

And yes, I'm aware of the consequences.

I always replace the catch spring with an industrial one. It prevents misfires without reducing the draw.

Thats really weird because I nested a #49 and a DoubleShot spring together in my NF and it works great! Its a bitch to cock but I'm getting low 90's with it. It probably wont last very long at all, but nothing is falling apart right now.

Epoxy should work just fine as long as you adhere it correctly. Roughen up the surfaces and clean them off. Then make sure your epoxy has equal portions of the two parts and that you mix it well. It should be able to hold that no problem. Otherwise you've got some real weak epoxy. Also, you can put some hotglue between the pieces and the shell to help reinforce it further, but you won't be able to remove the plunger tube after that without some work.

Seriously, I swear by Devcon Plastic Welder. It never fails. Plumbers goop has never been able to get the job done for me when it comes to nightfinders. If your other epoxy doesn't work, get yourself some plastic welder and do what Retiate said and rough up the surrounding areas.

I cleaned the surfaces off with alcohol before epoxy-ing. I guess that wasn't enough. I'll try roughing them and then epoxy them again.
