Quoted:
A PRI gasbuster does not help. It actually vents the gas right in the face of a lefty, just look at the design on the underside.
I am a lefty, and have a 12" SBR with a 5.56 suppressor. When I go to the range and shoot static, I hardly even notice it.
When I took it to a local carbine competition, I thought I was going to die. As you are dynamically moving and shooting at a rapid pace across multiple targets, especially when advancing forward, breathing becomes critical and something that was VERY hard to do with a suppressed SBR. I had issues with gas in my eyes, and mostly with the inability to take a deep breath.... choking on the gases. Yes, it is an issue.
I don't see how any lefty says it isn't.... but that's just me. Note, this is only an issue with the suppressor attached. When I take it off its no problem, just like any other AR.
I'll be investigating piston systems for my SBR, or playing with a switchblock type device. Leaning toward piston, as those vent the gases way forward.
That is interesting, my experiences in using a suppressed rifle in competition use are totally opposite.
Although the main weapon has not been a DI operated one, but a HK416.
I am a lefty and if firing slow on the range, yes you can notice the gas quite easily.
However in anything that is more dynamic shooting, I really do not notice it.
