Frequently Asked Questions

What gear was used for cold-weather shooting in the video?

The video features a Clam Corp Quick-Set Escape Shelter and a Coleman propane heater for a controlled environment. The BCM Mk12 rifle uses a Leupold Mark 6 optic and AEM5 silencer, while the Kel-Tec RFB is paired with an OSS Helix suppressor.

How did the BCM Mk12 perform with the AEM5 silencer?

The BCM Mk12 demonstrated sub-MOA accuracy at 150 yards. However, suppressor mirage became noticeable after about ten rounds, impacting sight picture during rapid fire.

What is the advantage of the OSS Helix suppressor system?

The OSS Helix suppressor is designed with low back-pressure, venting gases forward. This design helps prevent excessive blowback in semi-automatic firearms like the Kel-Tec RFB, improving reliability.
