building an AR platform .308 suggestions please!
So, I want to have a .308 in an AR config. I could just drop about 900-1000 on an FN knock off, but I really like the AR platform and how modular they can be.
Most particularly I'm looking for lessons learned and just general "things to consider" for example:
barrels - what twist is best on .308 out to 300-500 which is what I'd want this particular rifle to do, on iron sights (although I will probably put a scope on it and flip up/fold down front & rear "iron" sights)
barrels pt2... besides twist, length?
barrels pt3... besides twist and length, bullet weight. I want to feed NATO or civilian readily accessible ammo all day long without a hiccup and always on target... so what bullet weights and twist and length should I be considering?
with those in mind? Especially if you've built an AR type .308,
what have you learned?
what vendors would you do business with again EVERY TIME?
If you did it again, same gun, what would you do different?
Your thoughts on upper receiver bolt carrier groups?
a basic premise of what I'm planning to build...
standard .308 stripped lower
.308 parts kit /buffer spring / tube
magpul stock (adjustable cheek weld, shoulder mate and a spin down rear brace)
CAA ergo lower pistol grip (those are sexy if you havent seen one before, go look!!!!)
troy (probably, but open to suggestions) quad rails on front hand guard
GG&G or some other such dependable brand flip up/fold down front & rear sights
I will not be turning this into a $5,000 rifle with $500 compensators or some such accessories like that... my thoughts are building and assembling and coming in somewhere around 11-1300 and from there bolting on the add-ons like bi-pods and such. For now, I want the rifle to be up and working, that's task #1.
what are your thoughts and suggestions?
