Buffer Tube Assembly

[Mr-Derek]

I was going to grab the Mil-Spec Buffer Tube Assembly they have on sale at Brownells for a build I'm gathering parts for and it got me thinking.

Other than mil-spec or commercial do buffer tube assemblies matter or will cheap work as well as expensive? For an accuracy build can the buffer assembly effect function or accuracy?

Cheap example: http://www.brownells.com/rifle-parts...55-116241.aspx
Expensive example: http://www.brownells.com/rifle-parts...prod31717.aspx (I see even more expensive but they have counterweights and stuff so I wanted to keep it even)

Looks like the buffer is the difference. I've always used the standard milspec setups.

Won't affect accuracy whatsoever, it doesn't serve any function until after the bullet has already left the barrel... more expensive ones often have better fit and finish, maybe buffers that feel better, sound better, reduce felt recoil better, or cycle better, but otherwise no bearing whatsoever on the bullet trajectory. I suppose one could argue that rapid followup shots might be easier or harder with different buffers.

Buffer Tube Assembly

From my first hand experience, spend some extra money on a good quality buffer tube. My first one was canted and it caused failure to eject. Additionally, if your stock doesn't fit well into the buffer tube, it will wobble, preventing you from holding the weapon steady, which actually could significantly affect accuracy.

With that said, 100 is a lot to put into just the buffer system. maybe look for a compromise? Also read reviews. Might check Stag.

Part of that $100 is the pony tax.

A guy from my lhs showed me an integrated buffer/spring unit, said it was a lot smoother for competition use

Yep. Didn't see that. Colt bumps that price up 30%

That JP Enterprises Silent Captured System is super nice and I really link how smooth they feel. I just don't like the weight, they are heavy in comparison.

Also make sure it is 7000 series al. A lot of the cheap ones are 6k.

So as long as the tube is a good quality (7075) everything else is about the same it sounds like. Do you ever get variations in outside diameter of the tubes?

That pretty much sums it up...rapid recovery and spotting your own shots.staying on target......bullet flight path......no effect.

But that's really the buffer and spring isn't it?

I thought that's what the question was about... "buffer tube assembly", ie tube/buffer/spring/castle-nut/end-plate

You are correct, that was the question but I was double checking. If the soft feel and rapid recovery was only effected by the buffer and spring or is it all of it?

Yeah but if you combine it with the right components, it will make an AR that has very little recoil movement. It's 100% worth every penny.
