5 of 5 SPR Upper December 14, 2017
Reviewer: Andrew from Lillington NC  
While perusing my local gun show I came across John’s booth.  I was immediately impressed by the quality and specs of the SPR. A couple months and 200 answered questions later I took one home.  At the range it performed better than anticipated, a true tack driver.  I tried a host of different ammo from 43 gr. to 77 gr match and everything in between.   It shoots anything you feed it.  My best groups were with 43 grain hollowtip and 77 grain match grade.  Both of which stood up to the sub MOA guarantee.  Even bulk 55 grain held very respectable groups.  The upper matched seamlessly to my finished lower.  The only way it could have been any better is had I just purchased a complete rifle to begin with.  The customer service was great. All of my questions were answered plus some.   If you’re looking for a quality AR but don’t want to spend a fortune, don’t look any farther.  You won’t be disappointed.
