Today, I was testing my almost-finished longshot. For some reason, I decided to look at the bolt sled. To my horror, I found a hairline crack in it. So, I filled the crack with Zap-A-Gap and I intend to reinforce the living shit out of it. I was planning on doing that anyway, but I wasn't expecting it to break during a test fire. (I have a cut down AR-15 spring and the stock spring in it, so don't talk about the spring set-up.)

My general question is: Would a fiberglass repair kit or aluminum be better for reinforcement? Should I use both?

Thanks!

I would go with the aluminum, it is light and fairly sturdy. That is what I used to reinforce the Holy Nerf Cannon of Antioch.

As I work with metal, my vote goes to Aluminum.

put aluminum sheet on, then the fiberglass as a coat/glue/reinforcement. I just built a new one using aluminum as a skeleton, and adding fiberglasss as a shell.

I would say use Carbon Fiber. I just repaired my Recon with CF with Gorilla Glue, instant bond, and so far so good. I used carbon fiber rod, round and flat pieces. I will post some pics and hopefully get around to posting the full lessons learned on this modification. :D

Here are some pics of the carbon fiber:

I bought the CF at a hobby store for airplanes and you can most likely buy it online for less.
