View Full Version : DSA Barrels w/short gas tube

OK, maybe this is a stupid question, but what is the deal with the short gas tubes on the DSA barrels? This leaves half of the gas piston/spring exposed, is there a reason for this?

This is the common STG format.

The spring really isn't exposed, since its covered by the handguard.

The short tube is soldered in place. The tight solder seal, and the open end of the gas tube does have something to commend it for simplicity, reliability, and ease of maintenance.
