AR-15 BS Thread

I thought I saw a couple that were mid-length

I'll recheck. I know I saw a couple pistol length for 300 AAC. I was considering rifle length but they don't sell any of those...

 

Sorry, 556..looking for my first AR.

 

I'm with blackhawke all my rifles uses a carbine length gas system. I run an H buffer in them. Wolf cycles fine with all of them. If you are worried of being over pressured/gasses get an adjustable gas block.

 

That's because heavy buffers were designed to deal with over gassed carbine length not properly gassed mid length. Mid length is 100% reliable with all proper speccd ammo provided you aren't trying to fix your overgassed carbine gun (in your mid length upper)

I run tons of wolf through my rifles and they all run fine with standard buffer and spring and 3 I clock ejection.

Mid length will also have a lighter recoil pulse. Hell warsport took it one step further with rifle length gas on 14.5. A little uh wild but it works.

I sell tons of uppers all mid or rifle length and we have a no bs warrantee. They never seem to come back.

 

Midlength ftw.

 

Mid or rifle. Only reason to go carbine is for a SBR with a 10.5-12.5" barrel.

 

Thinking about selling my new AR already haha.....

 

I have never encountered any problems with carbine gas. H buffer, good brake, and auto carrier on a 14.5" LMT upper is smooth as butter.

 

I have. I haven't shot your rifle so I can't speak intelligently on that subject but I've shot many that were carbine gas with h-buffers. As for reliability they were generally fine but they all had a good bit of bounce. You generally won't notice it shooting static. Try moving quickly into a position though and putting 2 rounds into the head of a target. Better yet 2 or 3 targets. You'll notice very quickly that the sights bounce off of the target and take a while to settle back down. Its not really conducive to fast accurate shooting.

As the h-buffers, they exist yo bandaid the fact that the vast majority of carbine gassed guns are over gassed. That gas system was originally designed for the Colt Commando SBRs. It latter got put on the 14.5" m-4 but it was not optimized for it.

To minimize felt recoil you actually want less weight in the BCG and buffer, not more.

 

I understand what varying weights in an operating system does, but I see more issues with midlength 14.5" guns being unreliable than carbines. Not discounting the benefits of a midlength system, but if it comes down to it, I'll take a slightly overgassed carbine that runs my weakest handloads over a midlength that has even occasional short stroking issues with PMC or Tula. A tiny bit of flip doesn't bother me at all. I have a pimped out 18" rifle length upper with a low mass carrier and adjustable gas for when I'm worried about times, which is almost never

 

The problems in the mid gas are because people automatically put H buffers in them instead of shooting them first to realize they run correctly. LaRue next time you see a guy with a mid gas having issues, casually ask them what buffer and spring they have (this assuming the gas block is installed correctly) The majority of people have no idea what the varying weight buffers are actually for and just throw I'm in their gun from the get go then ask why it's short stroking. FYI spikes buffers are heavy buffers too. See that a lot.

I can't tell you how many times I see this.
I need some help my rifle is short stroking so I tried an H2 buffer from my normal H buffer. Uh if it's short stroking why would you go heavier? I don't know. Put a standard car buffer in. Wow thanks that worked it runs perfect now.

A note on gas blocks. They are 99 out of 100 times not supposed to be installed against the shoulder of the gas block area. They usually require a gap of roughly 1/16" to be properly aligned. That space is intended for the handguard plate that normally goes there for the standard plastic 2 piece handguards.

 

Haha. I just helped someone with this issue not more than a week ago.

 

Lol see! You don't run a shop single handed and not see tons of the same issues over and over.

I love this one. I don't know why my upper is suddenly hanging up. I couldn't trouble shoot over the phone so I had him send it in for repair.

Uh wtf

 

Good discussion on gas systems, much more clear than what I've read on some of the AR forums. Over there, they sort of make the OP feel silly for asking a seemingly obvious and trivial question then the 'experts' continue to argue which is best and a first time builder is left just as confused as when they asked the question...

 

Another good thing about being over-gassed is operating under adverse conditions with excessive fouling

 

True but how many of us do that in reality? So a better way would be to adjust gas down with adjustable gas block so you can open it up if needed not using a heavier buffer unless you carry various buffers with you when the Russians invade.

 

What in the world..?

 

not worried about the russians.....be realistic.....Zombies, dude!

 

I already have an ak for that scenario...

 

AKs belong in trash cans.










Sorry wrong forum.














Still true though.
