Mil-Spec Buffer Tube vs Commercial Buffer Tube

[spdlinegsr28]

Hi Ya'll,

I'm having a brain fart here and needs someone wisdom on my issue...I seem to be confused, whats the difference between a Milspec buffer tube and a Commercial buffer tube?

How can you tell if you have them side by side?

Any input would be great!! Thanks a lot guys!!

I got 2 commercial Rock Rivers from Midway and the charging handle hit both of them . I used a file and black leather dye to fix them. Next time,Mil-Spec.

Mil-spec is better. Slightly smaller in diameter but it is forged aluminum, not extruded which makes it stronger even though it's slightly smaller.

I've never heard of quality issues with the commercial type. Just because something is labled "mil spec" doesn't mean higher quality. For some reason ARFCOM loves that stuff. I've been building my own ARs for almost 10 years now and have built guns with both types of receiver extensions and never had an issue with the commercial type. The wobbles came from the "mil spec" tubes.

Wow thanks for the great inputs, but to your opinion which is better between the 2?

[rumble phish]

a mil-spec tube is STRONGER. It's not because it's called mil-spec that makes it better, it's because of the type of aluminum used.

Forged = stronger

extruded = weaker

will it make a difference at the range or plinking? Probably not, but I like to know that it is stronger material.

Take the measurements and compare them to the above graphic which notes the differences.

Well, I guess the CAA stocks works better with comm. stocks...I tried it on my other AR's and it wubbles...HHmmm..either I trade one of my Mils-spec tubes or buy a whole new butt stock...
