Building this was lots of fun!
Zediker's book
The Competitive AR15: Builders Guide was extremely helpful. Step-by-step instructions on lower assembly, basic upper parts, and barrel installation were great. The best part though was the four different builds including discussion of component selection and details on installation. The Geisselle trigger came with great instructions, as did the Yankee Hill Machine free float tube, but Zediker's step-by-step helped a lot too.
Specs minus rear sight:
- LRB upper and lower receivers
- White Oak Armament 16" stainless steel barrel w/ mid-length gas system 1:7 twist & lo profile gas block
- complete bolt carrier assembly including headspaced bolt, gas tube, lower parts kit, upper parts kit, A2 flash hider (all from WOA)
- Giesselle 2-stage SSA trigger group (5lb 5oz avg pull brand new)
- BCM medium charging handle
- YHM "customizable" rilfe length (12") handguard
- Troy Industries HK style fixed front sight (forend mount)
- Magpul MIAD pistol grip
- Magpul curved trigger guard
- Magpul AFG2 angled handstop/foregrip
- Magpul ACS-L buttstock
- Vltor "A5" receiver extension tube, buffer & buffer spring
- V-TAC quick adjust sling
- Double Star 5-slot 45 degree angled rail
- J Point Red Dot Sight (4 MOA) w/ mount
- Magpul P-Mags
YHM isn't making their fixed rear sight anytime real soon, so I ordered a DPMS unit. Then I discovered an alternative from LMT that has more elevation adjustment and looks much more solid. Bottom line: both are coming and I'll return the one I like less.
I haven't installed the red dot sight yet but wanted to post pics, so here it is minus rear sight and red dot:
I just finished it on Monday so it hasn't been to range yet but the weather forecast for this weekend looks good!
BTW the Magpul ACS-L stock fits nicely and locks up solid on the Vltor "A5" receiver extension tube. Comfortable cheekweld. 7 positions and length of pull from 11-3/4" to 15-1/4". I'd need longer arms for the full extension position...
Front sling mount needs to be moved all the way forward.
Finally,
THIS TOOL works like a champ for installing a barrel without putting any torque on the receiver, despite being a very tight fit in my upper receiver. Clamp your barrel nut tool in a vice, lower the barrel vertically through the barrel nut tool, apply torque wrench to the top of this thing, and job's done. (Brownells has a good video on how to use it that some of the reviewers obviously missed.)
