Basilisk Upper for Glock Gen 5/6

DO NOT ORDER THIS PART UNLESS YOU ALREADY HAVE ONE OF OUR FRAME MOUNTED LOWERS. 

The Underworld Arms Basilisk Upper is intended for customers who already own a frame  lower for their gen 5 or 6 Glock. 

The Basilisk Compensator for the Glock Gen 5 and 6 has the highest flip reduction of any comp we make. We achieved this by combining optimized ports, mechanical leverage via ambi thumb rests, and 3oz of non reciprocating mass (including weight of lower). 

This is a race style frame mounted compensator with two large expansion chamber top ports and slit style side ports. 

This compensator dramatically reduces recoil energy, as a result recoil spring tuning may be required.
