I ended up going with a Sig Brace.
You get the complete kit:
Shockwave Blade pistol stabilizer, black
KAK Shockwave tube
Mil-spec receiver endplate
Carbine buffer spring
Standard carbine buffer
$80 includes USPS shipping.
I will do PayPal, or Money Order.
If you do service, you pay the fee.
If you do gift, I expect a somewhat funny non firearms reference to avoid issues.
