Starting a Target/Bench AR build

[GarandThumb]

I posted a similar thread on ar15.com so if this is a dupe for anyone, apologies

This is going to take a few months. I plan to chronicle the whole build here in this thread and on YouTube.

Here is what I've got so far:

Upper and lower forged AP receivers
Port cover kit
Forward assist kit
Lower parts kit (cmmg) minus trigger and pistol grip


For the barrel/bolt I'm thinking about one of the fat barrels offered by precision firearms. Since this is going to be a long range rifle I was thinking about going 22 inches. I recall reading in this forum some guys were having problems with 24 inch barrels.. something to do with the gas system.


Anyway here are a couple of videos that provide a close up look at the receivers and port cover.

Comments and suggestions welcomed



***Update***

Just finished it this weekend.


Here is the parts list:

Upper/Lower: Aero Precision
Barrel: Lilja ar24 profile with thread protector
Float Tube: White Oak Armament Varmint
Gas Block: White Oak Armament match (non-adjustable)
Gas Tube: DPMS
Bolt: Underground Tactical (from Lilja)
Bolt Carrier: APF NiB
Port Cover: Tactical Junkie
Pistol Grip: Ergo
Forward Assist: DMPS
Lower Parts: CMMG
Trigger: CMC Flat
Charging Handle: BCM
Stock Kit: Magpul
Scope Mount: LaRue LT745


Scope: I purchased a Vortex HS-T intended for this rifle but it found a home on my Savage 260. For now I'll run this standard Vortex Viper but plan on picking up another HS-T

Also picked up two mags, one AR Stoner and one Alexander Arms, both 10 rounders. All told the whole build set me back $1800 (not counting scope). I will be taking it out next Sat to break in. I plan on using cheap steel cased wolf for the break in so I may not get a good idea on how well she shoots until the second outing. My expectations are 1/5 moa with tuned reloads.. hopefully my expectations are not too high
