Armalite ar-10 tac hg 12" - ArmaLite AR10 Tactical Handguard Kit

The TAC 12 looks like it will be a solid upgrade for my Armalite AR-10 Defender Sporting Rifle, once I get it, I also just order the rifle and the TAC 12 today on 08Aug15. I purchased an Armalite Low Pro Adjustable gas block. A Primary Arms 1x6 scope with a pair of Magpul offset sights. To top off this new battle rifle, I will be adding a Geissele SSA 2 stage trigger. My only problem is that they are never in stock. Took over a month plus for the rifle, as I ordered this Armalite AR-10 TAC 12" Handguard the same day as the rifle. I went from an AR-15 to an AR-15 Amped up to 6.8x43 "Love it" and now an AR-10 .308/7.62 X51.
