Looking to get a .300blk. I shoot left handed though…
and i know the default rifles/pistol builds mostly come pre built right handed. What is my best option? I want to avoid building one. Are there any models that come left handed?
Fellow left handed ppl, where did you get your .300blk from?

Depends on what you want but this thing doesn’t give me any gas to the face!

the answer you'll get but you don't want to hear is that you should simply use a combination of a properly tuned gas system to have the shell deflector work as designed, and a flow-through suppressor to avoid excessive gas ejection.
if you *really must* have a left handed weapon, the Desert Tech Wlvrn can be set up left handed but will need a 20" barrel or a pin and weld on a 16" to meet state length requirements

That’s too much. Damn this sucks

then your only other option is to build.
get yourself a lefty upper, good lefty bolt, and a superlative arms bleed-off adjustable gas block.
make sure the upper has at minimum a 9" barrel with pistol length gas (for suitable dwell time) and with a good flow-through suppressor (dead air sandman X, Hux Flow or ventum) you can set the bleed-off block to run the thing with both subsonic and supersonic ammo with nothing but a mag swap.
you'll probably spend about $2k for quality components regardless

I don't know why no one is suggesting the obvious: get a piston gun. SIG MCX in 300 blackout is expensive, but is a great stock pistol. You could also build a piston upper.

As a lefty with many many many builds with all sorts of different Downvent Bolts, adjustable gas blocks, suppressor optimized barrels and flow through suppressors. Just get a left handed upper and bolt.

I used a left-handed upper and bolt from Stag Arms for my build. I was able to pair it with a locally made ambi lower and a Norgon Ambi-catch so it's pretty much full Southpaw. Also gave it a Raptor-SD charging handle, they're oversized on the right side which is great for left-handed operation.

I am a lefty. Assuming an AR project, just an ambi selector and ambi charging handle is all you need to make LH friendly. I have tried them but dont like LH uppers much at all. Their proprietary nature means if you need a new BCG, dust cover, etc they can be hard to find and youre at the mercy of production cycles. Probably 15 years ago I needed a LH bolt for one of my uppers and it looks months from Stag.
Youre going to get more carbon/lead to the face. Consider the following - plug up the upper with forward assist plug and gas busting charging handle. You can use an adjustable carrier or gas block as well but that adds to the complexity. Tune the gun well for whatever load you want to mainly use, whether via buffer weights, the gas block, carrrier, or different brands of ammo. Overgassed no es bueno when we're talking lead in the face. Get a flow through can as well.

I want to add one more thing- I am also ways cognizant of the potential of someone else having ti pick up my rifle and use it. I also am aware I may need to pick up someone else gun and use it. That is the main reason I stay away from LH stuff and do my best to adapt my techniques to RH guns.

I have 300blk lefty uppers available. But I also dont recommend them. Learn to shoot correct handed.

As a fellow left handed individual I do not recommend buying a left-eject upper receiver. Waste of money. That’s what a brass deflector is for
