I've been toying with the idea for a little while. Never done it, and I'm curious. I've got a couple 5.56s and want something a little different. May let my daughter shoot a deer with it in the next year or two once she's comfortable. Even though we know a .223 is fine for deer. In a perfect world, I'd put together something "decent" for a few hundred bucks ($5-$600 maybe?). I don't need a match rifle or the most BA tactical weapon known to man. I'm not wanting to skimp and get the bottom of the barrell, but I don't need to drop a grand on my first build either. I don't know how realistic I'm being though. things like barrel, trigger, gas block/gas system I know are important. Not sure what brands are good, or junk, or over-priced, etc. I know of timney and geissele triggers and some basics. Any pointers, advice, recommendations, etc? Thanks, fellas.
