Description
Running a Strike Modular Chassis with a shorter slide means your support-hand thumb ends up sitting close to the muzzle, and that's exactly the problem this piece solves. The SMC-BS-H is the Hyper-length version of Strike Industries' blast shield, machined from 6061-T6 aluminum and finished in black. It slides over the chassis accessory rail and locks down with a cross bolt, redirecting muzzle blast forward and upward so it moves away from your face and off your thumb.
What the SMC-BS-H Hyper Shield Adds to Your Build
The big draw over the Standard shield is rail real estate. This Hyper version carries extra Picatinny length, which gives you room to run the SMC P320 Spare Magazine Holder and a full-size weapon light at the same time. That combination is normally a tight fit on the bare chassis, so if you're building out a competition or range setup and want a light plus a spare mag on board, the longer shield is the one to grab.
Aluminum Build and Fit on the SMC-BS-H
Strike went with 6061-T6 for a reason. Aluminum has solid thermal conductivity and sheds heat faster than steel, which matters when you're putting rounds downrange and the metal near your hand starts warming up. It stays lightweight and high-strength at the same time. While it's built around the Strike Modular Chassis for the SIG P320, the shield mounts to standard 1913 Picatinny rails and will fit most pistol frames with a max width of about 0.84 inches (21.20mm).
Getting the Most Out of It
One thing worth knowing up front: if you plan to run a compensator with your SMC Alpha or Bravo, Strike recommends sticking with comps that have vertical ports rather than lateral ports. Beyond that, installation is straightforward with the included hardware and Torx tool, and it bolts up as a natural extension of the chassis rail.

Frequently Asked Questions
What's the difference between the SMC-BS-H Hyper and the Standard blast shield?
The Hyper version carries more Picatinny rail length than the Standard shield. That extra length is what lets you mount both the SMC P320 Spare Magazine Holder and a full-size weapon light at the same time. Both shields protect your thumb from muzzle blast and heat, but the Hyper gives you the most room for accessories.
Do I really need a blast shield on my SMC Alpha or Bravo?
Strike strongly recommends one any time you run a slide shorter than full-size length, since your support-hand thumb ends up close to the muzzle. The shield redirects blast forward and upward and away from your hand and face. If you're running a full-size slide it's less critical, but most shorter-slide builds benefit from it.
Will the SMC-BS-H work with a compensator?
Yes, but Strike Industries recommends using comps with vertical ports only and advises against compensators with lateral ports on the SMC Alpha or Bravo. Sticking to vertical-port comps keeps the blast directed the way the shield is designed to handle it. Always match your comp to your slide's barrel length for the best fit.
Does the SMC-BS-H fit anything besides the Strike Modular Chassis?
It's built around the SMC for the SIG P320, but because it mounts to standard 1913 Picatinny rails it can fit most pistol frames with a max width of about 0.84 inches. That makes it a flexible option if you're working outside the standard SMC setup. Just confirm your frame width before ordering.
