Thats why you aim low left with subguns. Interesting. Whats the science behind that? A reflex to the expectation of the recoil? Quote Link to comment Share on other sites More sharing options...
shooterrex Posted June 14, 2019 Report Share Posted June 14, 2019 No body mechanics. If you look at AK47s the slash cut muzzle break pushes the muzzle down and left. My race gun shooting one handed goes up and right and you can watch it in the red dot. Left handed it goes up and left. Quote Link to comment Share on other sites More sharing options...

Also if at all possible id prefer one that doesnt redirect back to my face too much. Ive heard of this being an issue with some. Quote Link to comment Share on other sites More sharing options...

Flash hinders don't usually effect which way the muzzle goes when you pull the trigger. Quote Link to comment Share on other sites More sharing options...

Woah so this redirects gases forward after venting them upward?? Does it work? (am i understanding that correctly?)

Dexterity Posted August 29, 2019 Author Report Share Posted August 29, 2019 Anything fundamental with the gun I can do to lower recoil? I'm not sure if I mentioned it but I'd like to walk away from shooting with a not so bruised shoulder. I haven't gotten a comp yet but was wondering what all I can do to mitigate recoil. Will swapping the bcg for something lighter make a significant difference? Quote Link to comment Share on other sites More sharing options...

Swapping your BCG to something lighter is going to kick you HARDER... Edited August 29, 2019 by 98Z5V Quote Link to comment Share on other sites More sharing options...
Dexterity Posted August 29, 2019 Author Report Share Posted August 29, 2019 How do people setup their seemingly recoiless ar15's? I've heard an adjustable gas block is the finishing touch but I swear they reffered to it as "lightening" the bcg. Didn't make sense to me but I couldn't argue with the results. Also the only actual mods are the buffer you recommended and the springco spring. I bought psa's adjustable gas block when I got the gun but I've hesitated putting it on.

Just that, you set them up, balance the gas with the weight, spring strength, etc. I have a low mass build thread in the black rifle section. Problem is you are basically setting up the rifle to run good under one certain gas pressure, I only run one round, a Federal 55 grain 5.56, other ammo has function issues without making adjustments. Even then I see marks on the brass indicating early extraction. and almost forgot one of the more critical ingredients for a low mass lightweight build, MONEY. 308 AR's are different but most of the principals carry over, you will find copious amounts of reading here on the buffer system, gas system, etc. Speaking of we would need the details of your present system.

I'm fine with sticking to a single manufacturer for ammo. My current setup is mostly stock besides the springco orange 308 spring and this buffer https://www.primaryarms.com/expo-arms-308-heavy-carbine-buffer-5.3-oz I believe the gas tube is the wrong length like 98 said but it runs for now. I'll probably wait till it presents a problem to replace it. If I can't get the recoil down to a manageable level then I'll likely have to sell the gun as I need my wife to be able to shoot it.

I've recently purchased a complete lower and upper from PSA and want to share with you some things about my PA10 as I don't know much more than a few searches can tell me. So far PSA's shipping was stellar with only 4 days from purchase to arrival for both lower/upper. I've taken the infamous recoil system apart and behold. The weights come out to be 2.57oz with the spacer. 🤨 What else am I missing as far as the lower? Thanks. Going WAY back on this - are you absolutely positive about that combined weight of that buffer that PSA shipped you? That was 2.57oz?...

But that's what it said. I'll try again when I get to it. Quote Link to comment Share on other sites More sharing options...

It's an old scale that I'm not sure is accurate and I don't have a way of readily testing. But that's what it said. I'll try again when I get to it. Background for my question - a 2.500" aluminum-bodied buffer, with 2 tungsten weights, can only weigh a max of 3.8oz. 2.500" buffer bodies will only hold 2 weights in them. Your 2.500" buffer was 2.57oz. Each steel weight in a buffer is 0.65oz, each. Each tungsten weight in a buffer is 1.40oz, each. 2.500" buffer bodies with 2 tungsten weights weigh 3.8oz. 2.500" buffer bodies with 2 steel weights in them weigh 2.15oz. I only asked because that means they built that 2.500" buffer with one tungsten weight, and one steel weight, or something close to that. That's something that's not "Accidentally" done on the assembly line... Quote Link to comment Share on other sites More sharing options...
