Years ago, maybe around six(?), I got a pretty awesome deal on a Bushmaster Patrolman carbine. I have shot thousands of rounds through it with no problems at all other than maybe a fte? But that was after shooting hundreds of old dirty wolf, bottom of the barrel. *so i trust it in that since* but I have by no means gone through an intense class where i would put it to the test with thousands of rounds in one session. Shot it in the rain, snow, heat, everything... What I'm getting to... I see Bushy bashing all the time. I have never, personally, had a problem that I can remember to worry about reliability. I am wanting to start putting some money into it (an) AR. More specifically, would you guys set your eyes on building a completely new AR or would you change out the internals and keep the upper and lower, or? lol kinda long, sorry. Not usually one to ask others what to do with my own money but I hope some of you see where I'm coming from. thanks kids! Wanna kill these ads? We can help!
