S&W M&P 9 MM COMP for Stock Barrels
A small flat for timing is preferable to install the compensator. We offer this service free when you order your comp. You will need to send us your barrel to be timed with your comp, before we ship your order, so we can include your barrel return with your order.
If you want to have this service after you receive your comp, please include a postage paid paded envelope for return. (Shipping is not included unless we include with order made)
