Stag 10 Upper Receiver Assembly

(7 reviews) Write a Review

The Stag 10 upper receiver assembly includes a picatinny rail on the top, dust cover and forward assist.


Our upper receiver has the same barrel nut threads as DPMS, accepts DPMS barrels, accepts Stag, Armalite and DPMS BCGS and Charging Handles. Once matched with our custom Stag Lower, Takedown Pin, Pivot Pin and Takedown Pin Detent, this assembly can be built using standard DPMS components.


Pivot/Takedown Pin Size: .2770"  

Tang Height: .210 DPMS High Profile

Material: Forged and mil-spec with type 3 hard coat anodizing

SKU: STAG300044


Q: Are the bolt carrier and charging handle included?

A: The bolt carrier and charging handle are sold separately.

Q: Will this upper assembly work with other manufacturers?

A: Due to the Armalite Slant Cut, which was designed for a better fit, this upper will only work with our custom Stag Lower, Takedown Pin, Pivot Pin and Takedown Pin Detent. This upper is then compatible with DPMS components to complete builds.

    Fits perfectly on your stag lower

    I have the upper and lower finally. I need the handguard to finish the build. I know thinks are pretty tight right now but I hope I don't have to wait very long for them to come in stock.

    The receiver is very nice and no machining marks any where from what I can see .. it is a forged upper which is kinda of hard to find in 308 most stuff out there is billet ... I think it's the best of both worlds with the look of a kAC and or a armlite AR10 with the parts compatibility of the of the easier to find LR308 parts .... Top notch in my book and will be ordering more for my next m110 clone build

    Good value fits Mega lower partial fit to LMT

    Posted by Sid on 14th Sep 2020

    Excellent fit to Mega Lower. front take down holes not quite compatible with LMT
    Buy the stag lower takedown pin set and you can retro fit an LMT. front LMT pin slightly larger diameter than the stag.
    Overall very satisfied will buy from Stag again
