Custom & Upgraded S&W M&P 15-22 Rifles (12.5” Barrel)
Lightweight, accurate and endlessly adaptable, the Smith & Wesson M&P 15-22 has long been one of the UK’s most popular .22LR platforms.
What we’ve done is take that proven base and refine it into a compact, better-balanced and far more responsive rifle—ideal for practical shooting or simply a more enjoyable range experience.
We offer both ready-built rifles and fully custom builds, either from our own pre-owned base rifles or by upgrading your existing rifle to your exact specification.
The Magnum Arms Package (Example Build – Pictured)
The rifle shown is an example of one of our upgraded builds, designed to improve handling, ergonomics and overall shootability.
Standard £550 package includes:
- Barrel shortened to 12.5”
- Re-crowned and fully re-proofed
- Aftermarket free-float handguard (or modified OEM option)
- Barrel nut adaptor (replacing original quad rail (Mk1) or M-LOK (Mk2) handguard)
- Barrel shroud / muzzle device
- Magpul MOE (or equivalent) stock and pistol grip furniture
Recommended Upgrades
While the base rifle performs well, most customers choose to enhance the rifle further with a small number of key upgrades.
CMC 3.5lb Single-Stage Trigger (Highly Recommended)
A significant improvement over the factory trigger, offering a clean, crisp break that transforms how the rifle feels to shoot—particularly for fast, controlled shooting.
Ambidextrous Controls
Improved usability and faster manipulation, especially useful for practical shooting or dynamic use.
Extended Charging Handle
Easier operation and improved control, particularly when running optics.
Optics Packages
We can supply and fit a range of optics, including the Vortex Crossfire Red Dot — a lightweight, reliable option that pairs perfectly with this platform.
Configuration Options
Each rifle can be tailored to suit your preference:
- Alternative handguards (length / profile)
- Custom barrel lengths
- Choice of stocks and grips
- Muzzle devices / shrouds
- Optics packages
(Accessories shown in images may be optional and are available separately unless specified)
Why This Setup?
Shortening the barrel to 12.5” transforms the balance of the rifle, making it noticeably quicker to handle and more compact without sacrificing usability.
For those looking to take it a step further, upgrading the trigger and controls elevates the rifle from a solid platform to something genuinely refined—faster, smoother and far more engaging to shoot.
