Most Helpful Positive Review Excellent- spendy, but recommended
An upper worthy for the Boog. Superior fit and finish. Handles well in tight quarters/cqb environment- pair with an SB Tactical brace to avoid ATF NFA nonsense- I recommend the SBA3, as the cheekweld is closer to the SOPMOD stocks, as the cloners know. Is this a true clone? No. However, I have found the Geissele parts (upper reciever/super gas block) a better fit for this upper vs a true clone. The DD MK12 gas block may have potential clearance issues with the MK16 rail, whereas Geissele’s super gas block is more forgiving. Bombproof installation sums it up, with a pin and two set screws (witn...

The best upper I have!

by Hog, Verified Owner from AZ, United States Written on October 8, 2025
I mounted this on a Radian lower with a 3 gun trigger(same brand) and it's a 1 hole gun at 100 yards. It doesn't get any better than that.
Thanks OP!
P.S. Hornady 75 grain SP

Geissele Usasoc AR15/M4/M16 Upper Receiver Complete Group, Near Clone, 10.3in ML CHF, 5.56mm

by Person, Verified Owner from AA, United States Written on April 29, 2020
It's great. Comes with buffer spring and H3 buffer. Muzzle device will ring like a tuning fork, which may bother some people. Can't go wrong with this geissele/daniel defense/surefire mash-up.

The rail, while not particularly fragile, was deformed from over tightening of arisaka m-lok scout light mount, so there's that. Still works fine. It is a little pricey. You can save some more money by buying the stripped version of this (no H3 buffer, no buffer spring, no muzzle device, no BCG, no charging handle) and buy the rest of the components separately. The surefire muzzle device is the big spender here, and you can really get by with a surefire 3 prong instead or warcomp, because the 4-prong has the USASOC contract.
