I have a lower that I would like to install Ace's collapsible stock on but I am perplexed by the meaning of the following (in bold):
"M4 SOCOM Designed with input from combat experienced SF soldiers. This is the strongest production AR15/M16 stock available! Approximately 6 times stronger than an AR15 A2 stock & receiver extension tube. Ideal for CQB or breaching doors, and without the fear of bending the receiver extension tube ( which disables the rifle ). Adjustable length of pull, adjusts from 7.5" to 9.5" in five 1/2" increments. The M4 SOCOM comes with extra hardware so that it can be set up as a push button quick adjustable stock for "pre-ban" or "exempt" use; or as an adjustable stock for post ban use! ( M4 SOCOM has not been approved by the BATF for post ban use ).Closed-cell foam overtube provides an extremely comfortable cheek weld. This stock mounts "rock solid' to the rifle with no movement making it an ideal stock for precision shooting as well. Ambi-sling mount / gusset reinforces the receiver extension tube at its weakest point- just behind the receiver...blah,blah,blah..."
My lower was made in 2001. Can I use this thing? What about the extra hardware they mention...how does it work and can I use it in one of these mystery conditions?
Thanks,
K
