Griffin Armament’s C2E Contoured End Plate

While barrels, receivers, handguards, and other parts have a huge amount of options, the often overlooked end-plate is getting some love from Griffin Armament. Other options often focus on various attachment methods, Griffin instead took a different approach putting form in front of function with their C2E  Contour Connect End Plate.

The outside shape is designed specifically for forged receiver sets, where often the end plate is decided smaller than the back of the receiver. Towards the receiver, its flat, but the rear is chamfered nicely giving the plate a higher-end look.

Designed for seamless lines on a forged receiver set, the C2E does keep some function, including an 8-position anti-rotation Q/D socket. The C2E is manufactured from heat-treated ordnance steel and is manganese phosphated. Logos and external markings are kept to a minimum, with only a laser-engraved Griffin Armament logo present to remind one the manufacturer.


Specs (Courtesy of Griffin Armament):
–  Heat treated ordnance grade steel
–  Mil-Spec Manganese Phosphate finish
–  8 position Anti-Rotation QD Socket
–  Smooth contour matching geometry for Mil-Spec forged lower receivers
–  Minimalist value added firearm enhancement
–  Weight: 0.5 ounces

Pricing is set at $15.95 for the end plate. It is available directly from Griffin Armament or through their dealer and reseller network. The plate is compatible with both AR-15 and AR-10 platforms.

    I never really gave the plate much thought, but that does look quite nice! Thanks for the heads-up.

    It really does look nice. Little details make the whole thing stand out.

    GTFO, it’s an end plate, not a 5 series. Can I see an in depth review of turned detents please. And not the lowly steel type you peons use, but rather the platinum plated titanium type. It’s the only way to achieve 1/8 MOA from my liquid nitrogen set unobtainium barrel.

    • I’ve seen these made in China (bootleg or same factory?) for about five months now.

      I spend way too much time at work looking at gear on a weekly basis.

    I’m not sure how “Heat treated ordnance grade steel” will allow you to properly stake a castle nut in place.

      Stake harder? Braze and solder? Tack weld?

    Bought two of these. Looks nice on receiver, but at 0.166″ thick (versus a standard end plate
    at roughly 0.122″ thick), it was too thick for me to use. My pistol
    buffer tube would not reach far enough into the receiver to catch the
    buffer tube detent. Didn’t get a chance to try out the
    QD socket yet, though I like the idea of the 8 positions. I’ll attempt
    to return them as I can’t use them.
