I'm looking for a lightweight bullpup in the 500$ range. The artemus p15 was on the list until I saw it was hard to get parts. Now I'm looking at a flashpup. Anything else I should consider.It is for squirrel hunting.

Far superior to P-rod. 3x the air capacity, your choice of caliber, excellent stock design.
Under your budget!
Rapid 70 has that new bullpup kit for the Marauder pistol (aka P-rod) as well.
Not sure how heavy the entire thing is or how much it costs.
