when i am shooting/carrying right-handed, i place the forward QD on the L side and the rear stock mount on the R. with the sling tightened down, the rear either goes over the butt or over the top of the stock. switch both for L handed operation. (i have learned to shoot L or R handed due to R shoulder injury i am still rehabbing. in reality it has been good to be forced to train on my non-dominant side, because, you never know ...).
I have become a huge fan of Federal's reduced recoil ammo. Mainly due to flash out of my SBS. You can see 3 full-power and 3 reduced recoil flite control 9 pellet rounds used in this video, and EASILY tell them apart.
Just to update the backlog timeframe currently going on at Carrier Comp:
M4 7 round titanium mag tube order placed on March 5th. Just received a call (850 area code) to arrange credit card payment and to inform me that shipment is expected in approximately 2 weeks. So, slightly longer than the early to mid-June estimate from a month and a half ago.
They are very pleasant to converse with, both via email and over the phone.
