Spikes Upper
by Lou
Good fit / finish and matches my Spikes lower perfectly. I like the quality of Spikes products. And the price was right.Did have to eat some extra Wheaties though to get the Midwest Industries Gen 2 barrel nut to index to the next opening for my gas tube.
Awesome upper assembly!
