Most Helpful Positive Review Perfect Match
Ordered this upper to match with a lower I received from a local vendor. It was a perfect match as the description was exactly what I went by when I placed my order. After 500 rounds placed down range I did not have a single issue.
Most Helpful Negative Review Spikes tactical M4 upper
My first time buying from this site. I was excited to get my spikes upper for the price I got it for. When it arrived the packaging looked a little beat up. They didn't even bother to put paper or bubble wrap to protect it from getting banged around the delivery truck. When I took the upper out the ...

Loose tolerance scrap

by T.F., Verified Owner from N/A, Isle of Man Written on October 16, 2025
Steer clear of spikes uppers amd lowers for a while. These things should be labeled as tolerance blems. Pin lugs are undersize. Pin holes are oversized and yhe lugs arent even centered to the forging.

Spikes Tactical M4 Flat Top Upper

by JC, Verified Owner from KY, United States Written on March 21, 2025
I love ordering from O.P! They have great products, fast shipping, and fair prices! The Spikes Tactical M4 Flat Top Upper was bought to go with a Spikes Tactical Crusader Stripped Lower I already had. The upper looks okay. It does have a small blemish, but shouldn't affect function. Will update my review once I actually have the time to build it out.

spikes tactical stripped lower

by t, Verified Owner from WV, United States Written on March 7, 2025
This upper runs great with my 556 build with a palmetto bcg and bear creek barrel. This was a Frankenstein gun and I didn’t plan on making it a wall hanger or anything special, but the minus one star is nothing to do with the upper itself because it is great, it’s the packaging. They sent it in a bag. It wasn’t protective, in a box, or bubble wrapped at all, just a plastic shipping bag that was taped. Your shipper doesn’t know what they’re carrying so they aren’t always the easiest on your package, and upon opening my upper had a ding on the top rail close to the spider logo, and then another where the hand guard meets. This doesn’t affect functionality at all, and this isn’t a competition gun, but I would have liked to put dings in it myself over time, not have it arrive brand new with two blemishes because of the poor packaging choice
