Guys, new to the AR platform and just wanted your opinion. Picked up the DDM4 V5 last week and was wanting to know your preference for a rear sling mount? The DDM4 that I bought came with the rear QD swival attachment point but I can also attach to the rear buttstock (Magpul stock). What do you guys prefer? Sorry, if this is a newbie question but...Hey, I'm a newbie.
