NOTE: ANODIZING PROCESS OF FDE OR ODG MAY VARY FROM BATCH TO BATCH.
(Ejection Port Cover) is based on TDP dimensions, with thoughtful
Forward Control touches. Billet machined from 7075 aluminum, and hard
coat Type III anodized, it incorporates features we think many will find
EPC has two "tabs" flanking the cutout
for the port cover spring. These tabs allow the EPC to rest on the
upper at a greater angle when it's in the down/open position, which
provides more space between the port cover and lower receiver. Their job
is to better allow the user's finger to get underneath the port cover
when he wishes to swing it up/close.
Left: TDP ejection port cover. Right: EPC. Both in the down/open position. Please
note that depending on the upper receiver, the area below the ejection
port cover will vary in thickness, which affects the angle of the EPC
when the port cover is open/down.
feature is a shallow circular depression on the side of the EPC to
provide texture tactile feedback to the user's finger when he's closing
the EPC. A flat surface provides nothing to the user to differentiate
one surface from another, it also provides no traction. A shallow
circular depression on the left side of the EPC does both. We
incorporate flat surfaces with care as they have their uses . In this
case, EPC's exterior surface is treated as a control surface, where a
flat surface rarely makes sense.
EPC is compatible with TDP spec upper receivers.
Construction and coating: billet, type III anodized.
Proudly designed and made in the USA.
Initial closing and opening of EPC may be stiff, this is normal, and will become easier with 2 or 3 closing/opening cycles.
