About Us

We have been manufacturing Benelli m4 rails for over 13 years. We have manufactured rails systems under the names of Sidearmor and Asgard Defense Systems in the past. We are the same company, just a different name!

Pricing and Lead Time

We are currently manufacturing quick detachable shell holders and forward shell holders. Please allow 4-6 weeks for delivery. 

We raised our prices by $4 per product as the cost of aluminum has increased 100% as well as the cost of metal plating. 


We will ship all orders via USPS Priority Mail. A tracking number will be provided at the time of shipment. Please check your order status for updates on shipping.

Return Policy

All sales are final. There are no returns or refunds. If there is a problem with the rail system or shell holder, please contact us to evaluate for repair or replacement.
