Tighter tolerances allow for a tighter barrel fit which improves accuracy and finish. All of SIONICS premium receivers are THERMAL FIT to the barrel, this furthers the accuracy of the upper receiver group greatly. These uppers come with the SIONICS logo hard engraved above the charging handle and on the opposite side of the ejection port.
