AR556 Buffer change for 14.5 with midlength gas

Going from a 16" Carbine gas to a 14.5" Mid gas (with pinned/welded compensator0).. any buffer or buffer spring changes recommended with the change? Usually NATO 55gr rounds.

Thanks!

I think I would leave it alone unless you determine that the buffer is slamming in the tube. I doubt you will notice simply because you are going from a carbine length to a mid length. That direction typically indicates less buffer slamming because of the longer gas pulse.

So if I'm going from a slightly overgassed (stock, so it seems that everyone says so anyway) to a slightly undergassed setup, I should be fine... unless I have cycling issues. OK.

I have a RRA mid-length carbine that I got new as an HBAR in 2006. Way too heavy and not balanced the way I wanted it and so I sent it to ADCO in 2008 to have Steve re-profile the barrel to a lightweight and shorten it to 14.7". He pinned and welded the A2 FH to it so it was 16.1" and legal. The work took almost 1 lbs off the weight. I didn't change any springs or buffers.

I sent them a new front sight with a .675" hole (vs the std .750") so they could reduce the barrel under the sight as well. Steve gave it a target crown and opened up the gas port just slightly and it's worked slick as snot ever since. It's more accurate than it was when new and I can still shoot it out to 300yds at bowling pins.

Stock HBAR barrel:



My re-profiled and shortened one back from ADCO:



For grins, I added an Enidine buffer a couple years later and it still hasn't missed a beat. Weight and balance is great now and it's my lightweight irons gun. At 5lbs 15oz it's a great carbine.

Thanks for the replies and nice of you to post pictures. No buffer tube changes for me then.

Here's what I have gathered so far, and also adding a lighter and slightly longer hand guard and need a new gas tube of course... the gas port is slightly larger already on the Faxon barrel.

The Vortex is great but heavy so I may change that up, accuracy is no different than iron sights (shot a few hundred rounds standing both ways, on different days, and it looks the same)... but I can see what I hit better and it's very quick to line up a target. We'll see.

Buffer and Spring

H2 buffer and Geissele wire spring. You may find that using what you have may cause some FTE's or FTF's.
