Skyjacker Defense AR lowers

[ColbyBruce]

I traded into two of these last week, both NIB. My initial thought was to build a .300 Blackout and a 7.62x39mm or a .224 Valkyrie and a 6.8 spc. I have several .223/5.56x45mm rifles.

Skyjacker Defense is a metro Atlanta company. I have heard good and bad things about their products. I would appreciate any info you may have on these products as well as the calibers. Thank you.

My 300 BO upper has a tan hand guard, so I found tan mags for the 300 BO Ammo. Trying to keep things color coded.

One friend bought a PSA upper in 224 Valkyrie, and another bought a PSA upper in 6.5 Grendel. The 224V is running 1/2" MOA with Federal ammo. the 6.5 G is running 1.5 to 2 MOA with steel cased Wolf ammo.(I can't talk him into trying better ammo.

I would take the 6.5G over the Valk personally.

What brand are the tan mags marked .300 BO?

Why? I have not fired a Grendel but have some trigger time with a Valkyrie.

What brand are the tan mags marked .300 BO?

I have 3 tan, 30 round mags from Troy Industries, not marked 300 B.O. Every 223 mag has worked fine. I'm mostly sticking with sub-sonic 200 & 220 grain ammo. I find 110 & 125 grain 300 B.O. to be redundant for 7.62x39.

I have a few hundred factory brass (S&B) but have formed 800 from mixed military 5.56. Loads made with 15.5 gr. H/IMR 4227 have had the most reliability with suppressed sub-sonic loads and Berry's 220 grain plated bullet. 16" Stainless barrel length.
