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 always been one of the most popular .22LR platforms in the UK. What we’ve done here is take that proven base and refine it into something far more focused, compact and enjoyable to shoot.
We currently have rifles available to upgrade to your requirements, as shown, but we also offer a full customisation service for your own rifle— either built to order or upgrading your existing rifle to your exact specification.
The Magnum Arms Package (Example Build – pictured)

Re-crowned and fully re-proofed - Aftermarket free-float handguard

Custom Builds & Upgrades
Already own a 15-22?
We can apply the same upgrades — or build something completely bespoke.
Whether you want:
- A compact, lightweight setup
- A specific aesthetic or furniture package
- Performance upgrades (trigger / bolt / controls)
—we can configure the rifle around how you actually shoot.
Why This Setup?
Shortening the barrel to 12.5” transforms the balance of the rifle, making it quicker to handle and more compact without compromising usability. Combined with the upgraded trigger and bolt system, this results in a rifle that feels noticeably sharper, smoother and more responsive than standard.
