I agree that if you have an adjustable GB, messing with the buffer weights isn't really needed. StoneHendge did a good job of describing the difference in the "feel" of the recoil impulse. You can feel that there's more reciprocating mass with the heavier buffer, but IMO it cuts down on the initial "bang" of the recoil if that makes any sense. Kind of like the difference in shooting a sharp fast but low recoiling gun versus a heavier slower recoiling gun. This is all just based on my experience changing buffers in a carbine .223, have yet to test out the Grendel.

That's a great recommendation, I'm definitely thinking of going this route along with a heavy spring. The only extra heavy rifle buffer I could find was $115 which is just ridiculous. You rock!
this is the ticket!
a stock rifle buffer "should" work well enough . but a little tune up with these weights turned my rifle super slick-- a nice low buck option.

Heavy Buffer

Have you found a heavy rifle buffer anywhere? I want to try something heavier on my 22 Nosler to slow my bolt down but can't find anything other than the standard 5.4 oz rifle buffer for my ARFX. Seems that the only option would be doing a spacer and heavy carbine buffer/spring...
AR15R-XH - 11 ounces Rifle Buffer - $125
AR15R-XH 11oz Buffer + Wolff XP Spring - $140
Other weights available by custom order.
Recommended for use with suppressed weapons. Also a great option to help reduce recoil in non-suppressed guns.
Works great with the popular "Big-Bore" calibers - 450 Bushmaster, .458 SOCOM, .50 Beowulf, as well as 7.62x39mm and others.
Many customers use this buffer in standard .223 ARs to make shooting more comfortable for their spouses/youngsters.
Other weights available by custom order.
I strongly recommend this buffer if any of the following conditions apply:
If you will be shooting with a suppressor. (Your gun will still run fine unsuppressed with standard ammunition.)
If you will be shooting hot handloads or very heavy bullets.
If you want maximum recoil reduction.
I recommend using a Wolff XP rifle buffer springs with these buffers. Standard OEM springs or aftermarket springs from other manufacturers may cause malfunctions. 'Flat-Wire' springs are not recommended.

OP. can you tell us about the ammunition/load you are shooting and what barrel(gas port size) and gas block you are using?
From what I read on AlexanderArms.com, the standard buffer should be the appropriate one. I shot my brothers new build a few weeks ago and it was super soft. That was using an AA 18" barrel, Aero Precision gas block, and standard carbine buffer. Ammo was 123 Grain SST bullets over the just above starting charge recommended of IMR4198. Maybe as the loads get worked up closer to maximum recoil will go up, but I'd not imagine to distracting levels, but I'm curios now.

I'm shooting my BCA upper on a lower that has a Tubb's flat spring and Spikes H2 buffer. They seem to work great. I'm new to 6.5 so I don't have a comparison, but I didn't get any noise, or any noticeable issues with the buffer. There might be something better, dunno, but this seems good. The spring and buffer were a nice improvement with the stock .223 upper because it's a bit over-gassed.

Besides the holy cow price, you would be adding a buffer that weighs more than twice as much as a std rifle buffer and if your barrels gas port is drilled properly you may certainly find out that it is too much mass for proper operation and then it becomes a relic of overkill. Personally I rather buy some tungsten weights and swap them as I see fit if the need arises. Keeping in mind that a 18" or 20" barrel with a rifle gas system is typically a pretty soft shooting rifle if gassed properly.
I have a couple of rifles with Tubbs flatwire, to me they really don't seem to have extra strong spring weight like a wolf XP, but they do seem to provide a different spring cycle on how they compress and release. One thing that does ignore me about the flat wire style is that they are for me a minor pain in the a$$ to remove from the receiver extension as the flat wire tends to hang up a bit on the buffer detent. The bonus is they do seem to be more quiet in operation than a std round spring.

Heavy buffers are meant to counter bolt carrier bounce for full auto guns based on barrel mass, but can be used as rate reducers for guns that are gassed way too hard.
There are very few instances with 6.5 Grendel where you need an extremely heavy buffer.NRA Basic, Pistol, Rifle, Shotgun, RSO
