Yeah - the LaRue comes in pairs and I like this suggested use for a grip while the bottom mount turned around could still 'jack' the gun for stability.
I hadn't been looking for a while but I just bought an 80% lower and an upper yesterday sooooo....
Yeah - the Ares close out going on now ( with plenty of stock) includes a complete clamshell jig AND all bits and tools to complete the build for $50!!
I know others successfully completing them and bought one and an upper to get rolling.
I'm weighing what to build but have a number of guns that would be nice additions to the herd.
.458 SOCOM is probably #1 but brass is absent. .50 Beowulf brass is in stock but, 6.8 & 6.5 look good for real world applications.
