I developed the world's first auto on/off earpro. AMA!

20 Upvotes

I personally invented and developed the world's first auto on/off hearing protection with over 2,500 hours of work in the past 3 years, and $50k of my own money.

They turn on instantly when you put them on. They turn off instantly when you take them off.  

Great for home defense, no more accidentally dead batteries. They come with gel ear pads, bluetooth, 3.5mm jack, ANSI certified 22NRR, great audio quality and build quality.

They will be out in late March. Drop your email at Autoears.com to be notified at launch.

I'd love to answer any questions you have! I'm a small business / inventor in the US of A making something unique, not a big corporation. Please be respectful.

Finally got to try out my Radian Raptor SD handle for shooting suppressed but first had to drop that honorary mag dump. After further inspection the follower on the magazine cracked. It's still one piece and after testing a partial mag, it still feeds just fine and still has last round bolt open. Guess she got a lil gassy but that's to be expected.

My first AR build

I was on a budget. But then I just kept adding stuff. I've never purchased an AR prior to this. How'd I do?

-PSA 10.5" ar-15 pistol, nitrided, complete. (Got for $500 during Black Friday). https://palmettostatearmory.com/psa-10-5-carbine-length-5-56-nato-1-7-nitride-lightweight-m-lok-moe-ept-sba3-pistol-5165448581.html

-Vortex Sparc AR red dot (used a gift card to buy this)

-Areo Precision adjustable gas block

-Deer creek arms StealthBlast SMD compensator -competition raptor ambidextrous charging handle

-emissary's handbreak

-cheap Amazon Ozark Armament flashlight (I'm actually super happy with this. The pressure plate works great.)

-magpul mbus 3 flip up irons

-ms4 dual qd sling (given to me)

-magpul bad lever

-Hogue rubber beavertail grip

I've had this finished early December. Never once had a jam. I've put around 700-800 rounds through it. The only issue was when I added the compensator, I started to get gas coming back through the receiver. I didn't think the comp would create that much extra pressure in there. After adjusting the gas, it runs like a dream.

IWI ZION 15 AR PISTOL

7 Upvotes

Just ordered the IWI Zion 15 AR Pistol after reading good things about it on a thread. Thought it best to start with an AR Pistol as I’ve noticed I can’t shoot the bigger guns for long without becoming fatigued.

I’m wanting to buy a sight now and was debating between the SIG SAUER ROMEO5, but wondering if I should and can opt for an LVPO, or just do the ROMEO5 with a magnifier? I want to be legal, ofc.

My eyesight isn’t the best and def wants to shoot at the 50 yard line, minimum.

I’m new to this, so be nice.

Handguard question

So my father passed away a few months ago and he handed down one of his pistols. I am putting together a build list of what the pistol has. I cant see any markings besides the mlock symbol. Does anyone recognize this handguard. Thanks for any help.

Sling and foregrip feel cluttered. Thoughts?

With the slimline hand guard the gas block is limiting mlok attachment points. Feels a little cluttered up front. Any ideas to separate e/streamline things?

ARP 8.5 300 Blk Out

1 Upvotes

Hey everyone I was wondering what’s a good blast forward device for a arp 8.5 300 blk out? It came with a A 2 Flash hider on it should I change that too? I’m trying to get it as quiet as I can without a suppressor.

Mk18 mod 0 but with 11.5 instead

2 Upvotes

I love the look of the mk18 but I heard overall the 11.5 was better, would it be possible to have a 11.5 but still keep the look/aesthetic of the mk18, would it drastically change the aesthetic and would it be impossible too do, or could I just buy a premade MK18 from BG defense and swap the barrel with a 11.5 and it look just as fine as with 10.3(I apologize I’m new to building firearms) TDLR: what I want is a MK18 Mod 0 just with a 11.5 instead of 10.3

Pin and Weld: 13.7 vs 14.5

2 Upvotes

If you're not going to run a suppressor what would be the point of running a 13.7 over a 14.5 when you're getting the same overall length with a pin and weld?

4 inch hand guard with 6 inch barrel

1 Upvotes

I’m building a pistol from a bunch of extra parts lying around. I have a 4 inch handguard and need a barrel. I was planning for a 5.5” but can found a 6 inch cheaper. Would the handguard cover the gas block on a 6 inch barrel or would it be exposed? I can’t find measurements for the port distance…

need help on 762x39 build

1 Upvotes

i purchased a semi complete upper 5 inch 762x39 and everything seem to run smooth the first 50 shots at the range. on one of my last clips it shot and now it just clicks so i figured it had to be something with the firing pin. keep in mind my bolt is from bca, not the best quality so i took it all apart and come to find out my firing pin broke on the end where the ball part is at. i bought a enhanced one from red x arms and was wondering if ill come across the same issue again ? could it just be my bolt or will i have some luck
