Shipping & Returns
Shipping & Returns
If you order a product from DSC, we will stand by our product and correct/fix an issue if it may arise. Please note, no returns are accepted on custom barrel services/products or used drop-in barrels.
Return shipping may be asked for or necessary for projects that require sending in completes rather than parts - this is to insure proper insurance in the return shipping process.
DSC Drop In Barrels
DSC barrels are designed for drop-in installation, in conjunction with factory counterparts such as factory slide stop and recoil - we continuously strive to improve the quality of our drop-in barrels as each style and variant is custom-made, hand fitted to shop models, and coated per order.
Turnaround times are estimated to be approximately 5-7 weeks after the initial purchase, though they are subject to change depending on the situation. *Stainless variants may ship sooner, depending on the order.
**In the unlikely event that you experience any issues with installing your barrel, we offer free custom fitting.
