Why This Beats the Alternatives
Having tested suppressors from the Spring TX CNC floor to the 100-yard range we walk to, the Osprey 45 2.0 hits the sweet spot between price and performance. The offset design solves the #1 complaint about pistol suppressors – blocked sights – while maintaining exceptional sound reduction. Unlike cheap imports, it handles both pistol and subsonic rifle rounds without baffle strikes.

Pros & Cons

- Proven durability from Silencerco’s military contracts
- Easy to clean with simple disassembly

Who Should Buy This
Buy it if: You want a suppressor that works with standard sights on your .45 pistol or 300 BLK AR, need lightweight performance for carry guns, or prefer American-made durability without breaking the bank.
Skip it if: You need absolute maximum sound reduction (consider our rifle suppressors) or shoot primarily 9mm (the Osprey 9 is better suited).

Greg C. (verified owner) –
Bought this as part of a larger build project. F1firearms had the best price by a decent margin and shipping was fast. The Silencerco Osprey 45 2.0 Pistol Suppressor 45 ACP & 300 B… itself is well-made — Better than expected at this price. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.

Decent product for the price. Not the absolute best quality I’ve seen but it works well on my Glock 26. Would buy again if the price stays where it is.
