Excellent construction. by Edward P, Verified Owner, November 12, 2018
Ordered the 13.2 in M-lok barrel. It took a little longer to ship than I wanted, but it was worth the wait! The mated perfectly with my Spikes lower. Upper came greased and ready to go. No issues so far.

blemished unit by Paul, Verified Owner, March 15, 2022
The upper is everything it should be. Functions fine, nice accuracy. Ready to go, although the upper was blemished with a few different irregularity. Wouldnt expect this from spikes at all. Had a recent price drop but was not stated to be a blemished...
