Mass Driver Comp: Revolutionary Gen3 GLOCK Recoil Reducer

Upgrade your Gen3 GLOCK with Strike Industries’ groundbreaking Mass Driver Compensator (MDC). This innovative design revolutionizes recoil management without requiring a threaded barrel, making it 50-state legal.

Inspired by theoretical space propulsion, the MDC uses expelled gases to counterbalance mechanical recoil. Its unique separated design maintains near-stock cycling speeds while reducing reciprocating mass, ensuring reliable operation.

Note: Not recommended for +P and +P+ 9mm ammo. Installation by a gunsmith is recommended.

Highlights:

No threaded barrel required (compatible if present)
Widened bore reduces baffle strikes and keyholing
2.5mm relief cut prevents slide damage
Blended, no-snag profile fits most open-bottom holsters
Counter-recoil design for reduced felt recoil
Precision CNC machined for perfect fit

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.
