I'm looking for an affordable bullpup rifle for around $500. I have already looked into the Bushmaster M17S and read mixed reviews. I understand that any other bullpup (like the FAMAS, AUG, and Keltec to name a few) are usually over the $1000 mark. I'd like a balance of quality and affordability. I'm not so sure about kits, but if anyone can tell me something good about them, I might consider the option. I've also heard of an SKS bullpup... It sparked my interest, so any info would be great!
