Okay, I don't own any rifles yet. Mainly because I live in an apartment and don't want to put a 500lb safe in there. I'm waiting till I get my house, then gonna go for an AR15. I just want to know what to look for (mid grade to top brands), caliber, parts, just everything someone who is serious about a good quality weapon. Scopes n such. No crappy cool looking weight bearing crap that ppl put on theirs then can't hold it for long because it weighs 15 lbs. it's probably not gonna be for about 2yrs till I buy one, but I want to do ALOT of research for one so I ONLY need my one AR. U know. I am also left handed. Shoot pistols right/rifles lefty. It sucks but it works and feels comfy. What should I Research??? And what is a good price for an entry level that I can change parts out to fit me and make it deadlier. I have no idea about rifles but I tend to soon. Thank you guys. Also what about scoped hunting rifles for defense/hunting/long range targeting. If u guys can just throw out some names and calibers for that too as well. Again thanks.
