Best AR-15 Suppressor Host

This guide, drawing on the expertise of BurstReview, details how to optimize an AR-15 as a suppressor host. It emphasizes that a 20-inch barrel is superior for reducing shooter-experienced noise by moving the muzzle blast further away. The guide also covers considerations for gas systems, suppressor mounts like the SilencerCo ASR, and the use of a Gas Buster charging handle to mitigate blowback. It's noted that while suppressors reduce overall sound, 5.56/.223 supersonic ammunition will still produce a 'crack', making hearing protection advisable.

Quick Summary

A 20-inch barrel AR-15 is recommended as the best suppressor host because its increased length moves the muzzle blast further from the shooter's ear, significantly reducing perceived noise. While suppressors reduce sound, 5.56/.223 ammunition is typically supersonic, still producing a 'crack', so hearing protection is advised.

Frequently Asked Questions

What is the best barrel length for an AR-15 suppressor host?

For an AR-15, a 20-inch barrel is considered the optimal length for a suppressor host. This length effectively moves the muzzle blast further away from the shooter's ear, significantly reducing the perceived noise level during suppressed shooting.

Why is hearing protection still recommended when shooting a suppressed AR-15 with 5.56/.223 ammunition?

5.56x45mm and .223 Remington ammunition are almost always supersonic, meaning they travel faster than the speed of sound. This creates a distinct 'crack' sound wave that a suppressor can only partially mitigate. Therefore, hearing protection is advised for extended shooting sessions.

What are the benefits of a Gas Buster charging handle when using a suppressor?

A Gas Buster charging handle is designed to mitigate blowback by redirecting excess gas away from the shooter's face. This is particularly beneficial when shooting a suppressed AR-15, as suppressors can increase the amount of gas directed back into the action.

Does suppressor mounting affect firearm accuracy?

A securely mounted suppressor should not negatively impact firearm accuracy. If accuracy issues arise with a suppressor attached, it is often due to improper mounting, the suppressor itself, or the firearm's inherent accuracy, rather than the suppressor inherently degrading accuracy.
