Next-Gen Recoil Control for GLOCK Gen4

Elevate your Gen4 GLOCK’s performance with Strike Industries’ innovative Mass Driver Compensator (MDC). This cutting-edge design offers superior recoil management without the need for a threaded barrel, ensuring 50-state compliance.

Leveraging space-age concepts, the MDC harnesses expelled gases to counteract mechanical recoil. Its unique detached design preserves near-stock cycling speeds while minimizing reciprocating mass for consistent, reliable operation.

Note: Avoid use with +P and +P+ 9mm ammunition. Professional installation is recommended.

Highlights:

Compatible with non-threaded and threaded barrels
Enlarged bore minimizes baffle strikes and keyholing
2.5mm relief cut protects slide from damage
Streamlined, snag-free design fits most open-end holsters
Reciprocating mass reduction for improved cycling
Precision CNC machined for exact fitment

Strike Industries Warranty

How to return a defective item:

BEFORE returning any products, please visit the CONTACT US section to complete and submit the “Return for Refund/Exchange” form to receive an RMA (Return Merchandise Authorization) containing your name, shipping address, phone number, email, and reason for the return (including, if applicable, information about the firearm, ammo, and usage environment for defective returns). Please include a copy of the receipt if possible as well.
Once the RMA form has been processed, Strike Industries will provide a return shipping label for the refund or exchange of the product, including the shipping charges for non-expedited traceable shipping methods.
Wrap the item with sufficient padding and place it in an appropriate box or bubble mailer for shipping.
Ship out the package along with placing a printout of the RMA form we provided inside the box.
All processed and approved refunds will be applied to the credit card used during the original purchase. You should allow one to two billing cycles for the refund to appear on your statement.
Arrangements for a defective exchange or return must be made within one year of the warranty period, starting from the date the order is received. RMA numbers are valid for 14 days from the issue date. All packages received without an RMA number will be refunded, however, an automatic 20% handling fee ($2 minimum) will apply.
If the product was purchased from a 3rd party, Strike Industries provides no refund but only an exchange option.
