Being a lefty, LBP and flow through(TM) are super helpful. Didn't know what I didn't know when I started.
Can you explain what makes a suppressor "super helpful" for a lefty?
redneck explanation here....just an engineer or audiologist
The new generation of suppressors are Flow Through (huxwrx trademarked) so everyone is now using low back pressure or reduced back pressure as their terminology.
Standard baffle stack suppressors traps most of the explosive gas. That sends more gas than normal back through the gas tube and into the receiver. As a lefty, that ejection port is smack dab in our face.
With the introduction of additive material manufacturing (aka 3D printing) suppressor geometry can be designed and achieved that would never be capable in standard manufacturing. These new baffle and cores of LBP suppressors still trap the gas but allow it to vent out the front of the suppressor vs. back into the receiver and into my face! There are tradeoffs currently, LBP suppressors are typically more expensive and made of some exotic expensive metals like titanium and inconel. LBP suppressors are also a a few dBs louder as they choose less gas to face than total sound reduction. But from what I gather, dBs are not linear. So they are still "hearing safe" but typically louder. But most supersonic rounds, (ex: 5.56, 115g 9mm just to name couple) even with suppressors, will damage your hearing regardless with repetition and duration.
With a low back pressure suppressor, gas busting charging handle, weighted buffer and down vent BCG...as a lefty I can dump a full 30 round mag in FRT and not be crying or breathing out like it's my breathe on a cold winter day.
most of this is a moot point when you start talking bolt action rifles...but even there, these new 3d printed suppressors are lighter so perfect to trek with on a hunt.
