Duration: 10:36

This video provides initial impressions of two new suppressors: the Q Lefty and the Surefire RC4 Mini. The Q Lefty is a flow-through design with a unique tapered mount that tightens with firing, reportedly reducing blowback. The Surefire RC4 Mini is a shorter version of a conventional suppressor, favored for its reduced weight and improved maneuverability on the rifle. Both suppressors are noted for their effectiveness in reducing sound and concussion, though long-term reviews require more testing.

Quick Summary

The Q Lefty is a flow-through suppressor designed to minimize gas blowback, featuring a unique tapered mount that tightens with firing. The Surefire RC4 Mini is a compact suppressor valued for its reduced weight and improved rifle maneuverability. Both offer effective sound and flash suppression, but require more testing for long-term reviews.

Frequently Asked Questions

What are the key differences between flow-through and conventional suppressors?

Flow-through suppressors, like the Q Lefty, are designed to allow gas to exit the suppressor more directly, significantly reducing gas blowback to the shooter's face. Conventional suppressors trap more gas, which can lead to increased back pressure and a more noticeable gas signature.

How does the Q Lefty's mounting system work?

The Q Lefty uses a proprietary tapered mount system. While it looks like a direct thread, it's designed to tighten onto the muzzle device as the bullet passes through, theoretically preventing it from loosening during firing. Wrench flats are included for removal.

Why is adjusting the gas system important when using a suppressor?

Suppressors can alter the gas pressure and cycling impulse of a firearm. On rifles with adjustable gas blocks, tuning the system ensures reliable cycling, reduces felt recoil, and minimizes gas blowback, leading to a softer and more pleasant shooting experience.

What are the advantages of a mini suppressor like the Surefire RC4 Mini?

Mini suppressors, such as the Surefire RC4 Mini, offer a significant advantage in terms of reduced weight and length compared to full-size suppressors. This makes the rifle feel more maneuverable, especially during dynamic shooting or target transitions, while still providing substantial sound and flash reduction.
