A short term solution for BRD can be had in the form of accessories from AAC, Gem Tech, Yankee Hill or others!
My specific accessory is an AAC M4-2000 which has been a real #$@%# to get because of it's popularity. After you accessorize, in this manner, you may find this accessory item is needed for other guns not related to the BRD...say the 30 caliber or .22.....which really compounds things because you soon have both BRD and SD (not STD) diseases complementing each other.
