Accuracy is approximately as good s it was pre-mod (about 2 MOA @ 20 yards), though it's been in storage in a humid basement for a few years after the old stock broke and seems to have developed a pickyness WRT ammo
Overall, a build using inexpensive materials with a fairly low tool requirement.
All replacement components are fabricated from poplar, steel, or PVC and held together with epoxy or screws... plus a single rare earth magnet, and a tiny bit of aluminum and hot glue for the trigger. (Total cost for materials used was about 10$.)
You'll need a vice, a hacksaw, a drill, a set of files for wood, a set of files for metal (or a Dremel and a bench grinder), and some way to make boards of a specific thickness. A laser sight would be a real convenience, and a band-saw would make some steps a lot faster.
Because of the number of details in the project, I won't be doing a step-by-step for the entire project, just for a couple tricky bits. I will try to provide good pictures and descriptions to let you know what design-type stuff I came up with.
...to prime you, due to geometric dependencies, I recommend building the parts in the following order:
- Remove old stock. (Screws? Unscrews! Iron sights? Hacksaw!)
- Make forearm, except for scope-riser hole. (such that it fits in the receiver)
- Make Pistol-grip (such that it doesn't bang into forearm)
- Make Trigger group (such that it works inside the pistol-grip)
- Make Butt-stock (such that it gives you the right length-of-pull to the trigger)
- Make Scope Riser (such that it puts the scope in the right position)
- Finish forearm (with a hole that allows it to fit over the scope riser without touching it)
