Rosco/Forward Controls ACF-R, Ambi Charge Handle

FCD based ACF’s design on the TDP charging handle because like many other original designs, the charging handle is under appreciated for its simplicity and brilliance. ACF improves on the TDP design where possible but retains its best features.

• A taller and better gas deflection fence. ACF’s fence is taller than the upper receiver, and is horseshoe shaped to conform to the area of the upper where it meets the charging handle.
• The width of the T handle is barely wider than its TDP counterpart. The sole reason ACF’s T handle is wider is to provide protection to the latches.
• Retained the gentle rearward sweeping slope of the T handle and avoided a forward cant. A forward cant is more snag prone.
• ACF is significantly taller/thicker than the TDP design. Both the front strap and the curved back strap of the ACF are aggressively serrated. The back strap’s slight curve follows the curve of the user’s thumb. The tall profile of ACF’s T handle is designed to provide more surface area without making the T handle wider, which we deliberately avoided. Wide T handles are levers with mechanical advantage we don’t need, they also promote pulling the charging handle back at an angle. Small T handles encourage the user to pull the charging handle straight back, along the bore.
• A “constant motion” latch on either side of the T handle. The name derives from that the latches don’t come to a hard stop prematurely but will instead continue to move into the ACF’s T handle when mortared.
• Current production ACF-R uses roll pins (spring pins)
• ACF’s T handle is immovable and fixed in place like the TDP design. Like the TDP design, the fixed T handle is strong and has no moving parts.
