Frequently Asked Questions

What is the primary difference when shooting the McMillan CS5 with supersonic versus subsonic .30 caliber rounds?

When shooting the McMillan CS5 with an Elite Iron suppressor, supersonic rounds still produce significant noise requiring hearing protection. In contrast, subsonic rounds are dramatically quieter, often described as 'sweet whispers,' and may not necessitate hearing protection.

What ammunition types were tested on the McMillan CS5 sniper rifle?

The McMillan CS5 sniper rifle was tested with 168-grain supersonic .30 caliber rounds and Barnes 200-grain subsonic .30 caliber ammunition. The subsonic rounds were noted to travel at approximately 1,100 feet per second.

What is a key safety consideration when using suppressed firearms with different ammunition types?

A crucial safety consideration is understanding that even with a suppressor, supersonic ammunition generates substantial noise requiring hearing protection. Subsonic ammunition offers a quieter experience, but always assess the sound level before deciding against protection.

What does 'SBR' refer to in the context of the McMillan CS5?

SBR stands for Short Barrel Rifle. The McMillan CS5 is an SBR system, meaning it has a barrel shorter than 16 inches, which subjects it to specific federal regulations under the National Firearms Act (NFA).
