So what problem does the A5 kit solve that a 3.0, H1, H2, H3 buffer won't? Why is it worth it? At least JP can say their widget eliminates the 'boing' sound.
Most configurations will run with just an H buffer, granted they are ported properly.
However, the A5 will not only run, but it is extremely consistent with different loads.
With standard buffers you will see the ejection change, and feel the cycle change with hotter and weaker loads.
With the A5 it seems much less sensitive to this, and seems to cycle about the same no matter what.
An H2 with extra power spring impacts harder (leading to muzzle dip) than an A5 with more weight and a softer spring.
I know 5.56 recoil is already low, but the A5 makes it even better.
Nothing delivers as smooth a recoil pulse as the A5 system - nothing.
10.5" guns are notoriously finicky, and there is no standard buffer weight which will make them run, as gas port dimensions vary widely.
The fact is, there are dozens of posts over many threads on various forums where the A5 system has taken previously unreliable setups and made them function reliably with a wide variety of ammo.
It's certainly not mandatory to have a reliable gun, but it IS optimal.
If you're happy with your Hx buffers, drive on. I'm not going to tell you how to spend your money.

I think I'm going to give the a5 a try just got to get the parts now. They have one on BCM site that they call a intermediate buffer system. Seems it's the same as the Vltor a5...but maybe a different buffer? It's in stock. I think I found the Vltor parts in stock too I'll know Monday.
What barrel and adjustable gas block do you recommend....that might be in stock at some point in the near future lol

I stopped reading after the second "seems". Give me some empirical evidence because it sounds like they invented a longer buffer tube to sell a longer spring and proprietary buffer. You're still moving a mass and compressing a spring. I don't see how making the spring lighter and the mass heavier could make it more tolerant of various loads. Also, I'm not aware of an epidemic of rifles that won't cycle a large variety of ammo in their stock configuration. Thats why ALL production barrels are over gassed right now.

How much did all that cost you? I'm looking at putting one together with really similar parts.

I put an a5 system on one of my rifles just because I heard how reliable it was. So far I haven't had an issue, but I can't tell a difference in recoil. I probably should get a heavier buffer anyways.
I'll let you shoot it and we can compare recoil, I would really like to see if I can even feel a difference. Just name a time and place.

Came close to picking up an Anderson lower, parts kit, buffer and stock today at the local gun store.
I may go back and grab it tomorrow.

Anybody happen to have any leads on a Spikes Crusador stripped lower? I sure would like to get my hands on one.

I'm down. I'm not necessarily knocking the A5, I just don't understand how it could be better than the traditional setup using traditional H buffers given that it changes nothing about the underlying principal behind how it functions. To me it just doesn't seem worth it and could not be more tolerant than a buffer system tuned with H buffers. Its the same principal without the proprietary parts.

That's another reason I want to try one. Unkle jack is a buddy of mine and he is building a sbr too. So I want to do something different because we will end up shooting them side by side...would be a good test.
This place is where I just got my spikes billet upper and bcm lpk. His lpk showed out of stock on his site but he had a bunch and updated it. His home page says he has some but when you go to it it shows out. Shoot him a email and see if he has one. He was the only person I found with that spikes upper in stock after pages of google results.
Long dog tactical.

Around $900 not including sights

I'm not sure either because I'm pretty new to it at that level but I'm game to try some side by sides. I think the trick is the length of the spring maybe? A rifle length? maybe able to do something different with the buffers because of that? Idk

Big things come in small packages
LWRC PSD upper aimpoint H1, Troy BuIS
Spikes punisher lower with LWRC compact stock kit, ALG combat trigger BAD lever

Whatever works for you man.
I don't want a gaping port on my guns. Therefore, it's either going to be to spec or dialed down with an adjustable gas block.

The BCM intermediate is the same as the Vltor A5.
HOWEVER, the BCM kit comes with a A5H0, I think an A5H2 is a better place to start.
A 10.5 will definitely run with the A5H0, but as mentioned earlier, you're going to want to run the heaviest buffer possible.
My requirement for the optimal buffer is: lockback on the last round using the weakest ammo you will be shooting while holding with a loose/limp grip.

Not 100% on this but I think I saw an assembled one at Jims 2 Saturday's ago. Give them a call.

Yea that's what I noticed about the buffer. I'll look for the original a5 thanks.
LDT is out of the crusaders i emailed them last night.
