This Apex Barrel Fitting Fixture is built for gunsmiths and armorers who need a reliable, repeatable way to hand-fit barrels into S&W M&P and M&P M2.0 pistols. No guesswork, no expensive jigs — just a simple, durable tool that gets the job done for a flat $25.
Designed for use with a standard hand file, this fixture holds your barrel securely in two specific orientations so you can precisely trim the critical lockup surfaces. That means less wasted time and fewer ruined barrels.
Two Orientation Setup:
- Orientation 1 (Top Down): Locks the barrel vertically into the fixture for trimming the hood length. This ensures the barrel seats fully forward in the slide.
- Orientation 2 (Hood Against Base): Positions the barrel horizontally against the fixture base for trimming the bottom lockup surface. This controls how high the barrel tilts into battery.
Specs & Fitment:
- Works with Classic M&P barrels (full-size, compact, and shield models)
- Works with all M&P M2.0 barrels (including 4.25″, 5″, and compact variants)
- Material: 3D Poly — lighter and more durable than aluminum versions (per Apex, their poly tools outperform the older aluminum designs in both consistency and wear resistance)
- Designed for hand-filing only — no power tools required
Why this fixture makes sense for your shop:
- Eliminates the need for expensive mill work on drop-in barrels that still need fitting
- Reduces the time spent measuring and re-clamping — the fixture sets your angle every time
- Costs less than a single trip to a machine shop — pays for itself on the first barrel
- Compact enough to toss in a toolbox or range bag
What you’ll need:
You’ll want a flat, fine-tooth file to go with this. We stock the Barrel Fitting File 6in right here — it’s the right cut for M&P barrel steel and mates perfectly with this fixture. No need to hunt around for the right tool.
Bottom line: If you’re fitting barrels for yourself or customers, this is the cheap, repeatable way to do it. No fluff, no overpriced aluminum —
