Outstanding kit March 1, 2019
Reviewer: Chris from Rockmart , GA United States  
Get ready to deplete your stockpile of 22’s. I put the this upper together today and ran several mags and brands of ammo through it suppressed.  Zero malfunctions and all hearing safe, including SuperSonics.  I am very happy with this product and the extremely fast shipping.
