How the Mossberg Chainsaw Stacks Up
Most buyers compare this against two options: cheap Turkish imports ($250-$300 range) or premium tactical shotguns like the Remington 870 TAC-14 ($500+). Here’s why the Mossberg Chainsaw splits the difference:
| Mossberg Chainsaw | Turkish Import (Hawk 982) | Remington 870 TAC-14 | |
|---|---|---|---|
| Material | Steel receiver, aluminum trigger guard | Mixed metals (pot metal parts) | All-steel construction |
| Quality | Mossberg’s proven 590 action | Questionable heat treatment | Remington’s post-bankruptcy QC issues |
| Compatibility | 590-series accessories | Limited aftermarket | 870-series accessories |
| Price | $367.99 | $279 | $529 |
Why This Wins for Home Defense
The Chainsaw earns its name from the aggressive pistol grip that lets you control recoil like a power tool. After testing 50+ pump actions, here’s what stands out:
- 18.5″ barrel keeps it maneuverable in hallways
- 3″ chamber handles heavier defensive loads
- 5+1 capacity with 2.75″ shells
- Dual extractors prevent jams (unlike some imports)
Key Features
- Pump Action: Mossberg’s smooth 590 action with positive shell lockup
- Safety: Tang-mounted for ambidextrous use
- Sights: Bead front sight for fast target acquisition
- Finish: Matte black oxide resists corrosion

No – the 18.5″ barrel and 26.37″ overall length keep it compliant as a standard firearm in most states.
What shells does it chamber?
2.75″ or 3″ 12 gauge shells (5+1 capacity with 2.75″).
