Ideal Rifle Buffer/Spring for Grendel

[Lastrites]

[quote=Chrazy-Chris]


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.

With or without an adjustable gb?

I am running the JP SCS H2 version with my JP 22er and recoil is absurdly low. Also have JP LM carrier and compensator and its in a PRS (heavy) which obviously also help with recoil too.

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 Wolff XP rifle buffer spring - $140

AR15R-XH - 11 ounces Buffer Only $125

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.

So, you've got me seriously considering this buffer/spring combination for the target build I'm working on. Other than price, are there any potential disadvantages to this setup over say, a Tubbs flatwire spring and a standard rifle buffer?

[Kilco]

I use the Geissele 42 on my 16" ultralite Grendel with the H1 buffer and it performs flawlessly and is extremely quiet.

I also run a Odin Works Atlas comp so recoil is non-distant. It's like a soft 5.56.

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.

I have a 24 inch bull barrel for this build so the weight to counterbalance that is actually desirable. Am I significantly risking reliability if I pick up the heavy buffer? I'll mostly be shooting Hornady/AA factory ammo but might run a few boxes of the Wolf stuff just for fun.

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.

As I've gathered you're pretty much the Patron Saint/Godfather of 6.5 Grendel wisdom around here, Tubbs Flatwire and standard rifle buffer it is.

I've long been a fan of 6.5 ballistics (from the Swede on up) and Mr. Alexander's ingenuity. Sorry to see him leave AA, but was thrilled to learn he was pursuing an opportunity with "the defense industry"
The Grendel is the cartridge our armed forces deserve, not 5.56 peashooters.
