Quick Tip: Benefits of an A5 Buffer in Your AR-15
Спорт
Sometimes we all need a buffer from life's problems, and today Brownells Gun Tech™ Steve Ostrem talks to Mike Mihalski, founder and owner of Sons of Liberty Gun Works (SOLGW), about how an A5 buffer system can solve functional problems on an AR-15 carbine. The A5 does for the rear of the AR-15's operating system what the mid-length gas system did for the front end. As Mike explains it, the original M16 with a 20" barrel was a balanced "algebra equation" in the form of a smooth-operating rifle. Once folks started shortening the platform, the operating cycle became more abrupt and reliability problems ensued. Also called an "intermediate" operating system, the A5 restores much of the balance of the original AR-15 rifle. The A5's slightly longer receiver extension (aka "buffer tube") accommodates a longer buffer spring and a longer, heavier buffer. The heavier buffer reduces carrier speed and provides extra mass to return the bolt to battery. Extra buffer weight also makes the gun more forgiving of "hot" ammo and shooting with a suppressor, so an AR-15 with an A5 buffer can handle a wider variety of ammo. The longer buffer spring results in smoother cycling rifle. Bonus: felt recoil is reduced AND there's less risk of a broken extractor. Give the A5 a try!

After upgrading my AR's to A5 buffer systems a couple years ago per Mike's advice I can attest that they make a pretty big difference. It feels better overall, but a big thing is it gives any rifle less recoil. Buffer weights is also a big thing to look into. Most 12.5-16 inch middys will work great with h2 which most prebuilt AR's these days come with the lightest possible buffer weights.

I have a KS-47 build that I did something similar on. I didn't know about the A5 system, so I took a rifle length buffer spring and paired it with a KAK variable buffer, using the 3 tungsten weights. It really took the snap out of the 7.62x39 and has become my go to.
Mike, good stuff!!!! And, I love the algebra equation analogy. Just switching over to the A5 system in my carbine. Also, Mike, I would recommend the Tubb flat spring....spring is universal for both rifle and carbine.
Great video, use nothing but a5’s since getting to meet Mike and having an awesome two day course about the ar15. Never stop learning, he is truly an encyclopedia of knowledge.
Well explained for a newbie thank you!
Good points. Although I don't shoot suppressed or have short barreled guns, I have various heavy buffers on all my mid-length and rifle length rifles. Less recoil, stronger charge back into battery, and easier on extractors.
Always wondered did I need the A5 system, this video just answered my question.

My first AR was a Aero Middy “build”. I can’t remember if I had put a H1 or H2 buffer in it, but it was a smooth shooter. Only problem I had was the FSB was canted. And I had only found out after I replaced it with a picatinny gas block, that the gas port was drilled off center.
This is my future upgrade for my build, I've been a fan of this company for years. I'm running VLTOR MUR upper receiver, gas block, charging handle and honestly they make the best uppers, I use them on both my rifles. You have to take a piece of 2x4 and tap the receiver onto the barrel because the tolerance is so tight and when you work the bolt carrier it is very quiet and smooth right out of the box. The parent company makes Aerospace products and other things for the defense industry.
VLTOR A5 system is hands down one of the best upgrades you can do for a carbine.
Excellent presentation. That explains so many things as many people think they connect any upper to any lower is not correct. You need to get proper buffer & spring to match the upper.

This is my favorite system. L.A.R.B mod 3 buffers work great with the 5/8 longer a5 buffer tubes.
I like that someone actually engineered this to be correct, not just a cut it down and tweak it enough to run. I wish Brownell's would manufacture an adjustable gas block for various weapons. The AR would be good and I personally would like to have them for AKs. A lot of weapons are 'overgassed' as a 'band aid' for reliability issues. A correctly gassed weapon doesn't slam it's internals against the rear of the action. Nice video. Ya'll Take Care and be safe, John

Thank you very much.
Correct information.
The a5 tube and standard carbine buffer is a terrific alternative on a 308/ar10 type rifle as well
I needed to use an A5 extension with a shorty carbine buffer in my 308 AR10. A standard carbine buffer/extension combo didn’t have the really estate for the carrier to go all the way back to grab the next round or even to lock the bolt to the rear.
You can use a carbine spring and buffer in a rifle buffer tubes by inserting a plug into the tube of the rifle stock equalizing the internal capacity of the carbine
I wish I had seen this before I invested in an aftermarket spring and adjustable buffer for my carbine. What he says is pure common sense but my mind was fixated on "carbine parts".
Love the A5. I just wish they were more available.

Agreed 100%
Mike is a boss
This makes perfect sense. A longer buffer tube & spring, allows the buffer weight to cycle better and easier. Without slamming the back of the buffer tube. So it probably operates as smooth as a sewing machine! This would be nice on big bore guns, with heavy recoil.
I guess I am just Old Corps, but I love the rifle version of the AR15/M16. I have never been fond of the adjustable stock on the carbine. My carbines both have fixed rifle length stocks with rifle buffers on them. I noticed a real improvement in the recoil department when I changed stocks. Just my two cents worth.

As an owner of a 20" A2 style AR, I can confirm its very smooth and soft shooting.
Does the intermediate buffer come with tungsten wts? For the cheapo overgassed uppers that I use in calibers such as 7.62x39, I have found that tungsten wts make all of the difference in slowing down the BCG carriers as shown by ejection pattern.

Question about the A5 system. If you have an AR that will fire and eject the spent casing but not pick up a new round from the magazine unless you use a lighter buffer and spring, what will the A5 system do to it? I imagine with the extended stroke it would make it fail to pick up a new round. But I’m not sure I completely understand this system
@DBravo29er

Well, the A5 system has more consistent spring tension from in-battery to out of battery. Meaning tias it's less dependent on spring strength more dependent upon buffer mass. This is a much more reliable way to regulate function. For you, what buffer are you running now, with what spring?

The majority of adjustable gas systems for direct impingement ARs are of gas system set screw adjustment design. The set screw either loosens up or in certain instances become carbon locked. It's a finicky and unreliable method of adjusting the gas system which can result in short stroking failures. In theory it's only beneficial for sound suppressor to reduce backpressure. However, low backpressure suppressor makes an adjustable gas system unnecessary. There's also the option of using enhanced BCG specifically for suppressed AR carbines which will vent off extra gas - the LMT enhanced BCG and Gemtech suppressed BCG
I'm currently building an AR308 with Aero Precision parts, 16 inch barrel with mid length gas block and was told I can run a AR carbine weight with a 308 rifle spring. I'll be using the Magpul UBR stock and was wondering if this set up will work? Any input is appreciated.

Just make sure you get the correct t length receiver extension (buffer tube) AR-10 (armalite) used the intermediate receiver extension and a standard length buffer. LR-308 (DPMS) used a standard carbine extension and a special short buffer that they did not show in this video. I've put together both versions and I've had guns put together by shops that didn't know any better. I had to fix their mistake. Also, my Aero 16" build is very overgassed. Aero barrel. My buddy's 18" faxon barrel was also overgassed. An adjustable gas block was the best option for taming excessive recoil, combined with appropriate muzzle device. This was after maxing out the buffer weights on both setups.
Can I use a blue springco spring with this system? Or do I have to use the longer spring?
Where can I find out more about buffers and springs? Like what kind of buffer for a 10-in or what kind of spring for a 16 in, stuff like that
