Hello, new guy to the forum, great info on here! I have been thinking about doing this for some time after seeing a couple people build their lowers. Seems like a fun project, but like any other hobby cars, comps, etc I can see it becoming an expensive and addicting hobby. So ill jump into it I will be building my first AR-15. Now this is my first AR, however I have been around rifles and other firearms most of my life i.e hunting with the pops, going to the range, some handgun aspects etc. Back on topic I will say the main purpose of this rifle is target / shtf, however accuracy is still a big part, but for a tactical carbine style AR I am paying close attention to weight. In essence FFR is not a priority (This may change). I picked up a Stripped Stag lower. Grabbing a PSA Lower build kit w/ milspec CTR & Miad grip soon, just trying to choose which color to go with I would grab the MOE kit but I am fond of the CTR friction lock. Onto the upper. Well this aspect is still in the air. I am looking for 5.56 chambered. Barrel wise I am fond of medium profile maybe heavy but no pencil barrels. I would run a PSA upper but the 1:7 twist standard HF barrels they run I think as of what I know about twist v. weight (which is minimal) and grain will be to aggressive for the budget ammo for target shooting. Looking in the 16" barrel size. I have checked out BCM and Del-ton as well as RRA and other mainstream manufacturers. In the same retrospect I am thinking about building my own upper. This all seems straight forward w/ proper gas tube sizing and tq specs, but that's what I said about the first time I stripped an engine haha. I am looking for some guidance in choosing which way to go with this. I am open to all brands granted this is on a budget but I am open to widen that IF I can truly justify the reason. Again I will say thank you in advance for any and all help. I am looking forward to this build and with any build I'm sure things will change. Comments welcome!
