H2, H1 or CAR Buffer tube on Midlength gas AR platform

[etwinam]

I am doing my 2nd build for an AR15 and this build is going to be premium and lightweight. I am curious about the buffer tube weight.

I have a H2 on my current gun but I am afraid with the lighter build that it will effect the performance.

Additionally my current AR is a carbine length and I am going midlength this time. Any advice is greatly appreciated

Also so on a side note, what is the best lightweight Buttstock that is still premium and helps absorb recoil and cheek slap?

I run standard weight in all my 5.56 rifles. Never had an issue. Id stick with that, and try the H2 while you are out zeroing the rifle. Buttstocks wont add significant weight, and a heavier one in the rear (like an LMT SOPMOD) may make the front feel even lighter.

Vltor A5 system and never look back! My rifle feels like a .22, but maybe that's only after shooting .308 all day.. Jokes aside, the A5 system is very nice and a tremendous difference in recoil

I run a Magpul ACS-L now and I want something lighter ... perhaps no storage just padding.

I'm also wondering what is the right buffer for a standard 223/556.

I've read that the h2 is good for 300blkout and suppressors while the standard weight will cycle the 223s better on our non sbr. Is this true?

I'm looking into the JP silent capture standard for my 223/556 build

Thank you , this is exactly what I was hoping to find out, Is it really good? 5.3 oz weight compared to a H2 4.6 oz !!!! Seems even more counter productive than an H2. Will .223 cycle?

Mine eats anything I feed it, steel case included

i run H2 in my 16" carbine gas

i use standard CAR buffer for my 16" mid length

Use the heaviest buffer it will function with .
Load 1 round and shoot it.. if the bolt stays open move up to next heavier buffer weight.
Do it again with the heavier buffer until the Bolt doesnt stay open or lock back, THEN GO DOWN to the Lower buffer weight that functions properly..
You want the bolt to lock back each time with single shot testing.
Start with lite buffer then H1, H2 and so on..

I use a H1 buffer for my Midlength with no problems. I did the same thing Truck286 talks about.

[ZombieLivesMatter]

I used a CAR buffer on my latest midlength build and tested 600 rounds through it no problem.

I found this chart helpful, especially when I started getting into AR10s. For midlength you won't go wrong with H1, if you don't have all the different weights to try to see the heaviest you can go without cycling issues. Most likely, will have no issues with H2 as well.

All these lightweight stocks worked great for me: B5 Sopmod Bravo, Rogers Super-stoc, MFT minimalist... but they are all cheaper, budget options. Not sure if stocks are premium enough for the build you are going for.

I use a standard buffer and full auto carrier in all my ars. Never had an issue. For reference the spikes crusader has a mid length 14.5 lightweight barrel. Light weight carrier and an h2. My friend has one and it shoots great.

The answer to which buffer also depends on what spring and BCG(M16/AR15) you are running? Personally I like the Tubbs flat wire spring. Matched with an H2 or H3 buffer, full weight (M16) BCG and mid length gas system = very smooth running rifles. Plus, the Tubbs greatly reduces the "twang"/"sprong" sound heard by the shooter and so common to ARs. Oh and the Tubbs peak performance range is 10x longer than any basic AR(M4) buffer spring.

For a stock I would recommend not going light weight with a light weight barrel. A heavier stock will help balance the rifles weight rearward providing for a better balance between the rifle and yourself. Better balance = smoother operation and easier to stay on target and shoot fast. For this reason I like Magpul UBR stocks, expensive yes, heavy yes, solid as a rock yes, and they provide a balance favored slightly rear which makes presenting the rifle on target far less draining over time

My 2 cent.

KAW Valley also makes a decent heavy buffer, slightly cheaper than the Spikes. Both filled with Tungsten sand. I've been running the KV with a JP polished and tuned spring, Vltor Buffer tube, and it's been butter.
