Hey NES, I'm looking to build my first .308 AR and need some advice on the best parts(receiver, barrel, lower, BCG)
What are your favorites?
Thanks,
Will

What's your budget??

I was able to completely build my first AR10 in .308 Winchester, for under a grand total. I still don't have an optic on it, which will probably cost more than I have into the rifle. I have my eyes on one scope that runs about $1200 (a 10-50 x60)... I need the higher magnification since I want to actually SEE what I'm shooting at out beyond 500 yards. [smile]

Good topic. I need input also.

Trying to pick a barrel and buffer

I'm thinking about an 18 inch mid length for barrel but stock , buffer, and buffer spring components are confusing. My preference is a fixed skeleton style stock but buffer choices are confusing.

Any suggestions especially with experience.

I'm not going into battle so I have a Bushnell AR/223 Tactical 4.5-18x40mm scope with a Custom Turret Label on the elevation turret. It is your money, but this scope works great for only 200$. It is light and the turrets are as accurate as my Vortex 6-24x50 PST FFP MOA scope. At 18 power I can see the .223 bullet holes in my 100 yard targets. Mine shoots less than 1/2" five shot groups at 100 yds with 65 grain Sierra Game Kings and 3/8" five shot groups with 69 grain Match Kings.

OH, I use my PST at 24 power on my 6mm Norma BR. 1,000 yd rifle that I use in competition at 1,000 yards. My best 5 shot group so far with that rifle was 3.25" at 1,000 yds.

The mirage gets worse as your power increases until you get above 60 power when it "kind of" disapears. You may not believe this, but it is true. That's why the guys with deep pockets use 10-80x56 March scopes.

Rifle came out pretty sweet at that price point too!

Too bad there isnt an entire forum on here that could provide information like this.

Listen man, I didn't post for the snarky comments. I've looked for two months on this forum and couldn't find one specific answer to question. So I started a new thread.

For anyone who is following I just bought 2 Mega Lowers. Got them for a great price. I will post pics when I figure out how to upload them.

I put a few PSA 308s together over the last few months. Parts compatibility with AR-10s sucks in general but a little time on ARF got it squared away. One is a nice 20" rifle build, the other a 16" carbine I put together from a stripped upper / blem lower as cheaply as possible - about $850 all in, just broke it in a few days back.

MEGA makes nice parts. What u looking to spend?

MEGA makes awesome 308 upper/lower and handguard sets. I built a rifle with one, and it awesome... :)

I am using a heavy 308 rifle buffer and spring. If anyone wants specific parts I can add tonight.

It is an 18" Mega barrel (allegedly made by Bergara but not 100% on that, it was on the internet :) )
BCG is a NiB 308 bcg and bolt from Ares Armor (now AWC)
Buffer is an XH Heavy Rifle Buffer and Spring from heavybuffers.com

Without optics it was like 8 1/4 lbs or something like that, I will have to check...
