Picked up a stripped lower today. I'm shopping parts. Mil spec or Commercial buffer tube?

What say you?
 
Major difference it the diameter of the tube.. that is the 'common' meaning of the term... to distinguish them
when boiling down the specs though... Mil spec 'should' have rolled threads versus cut threads, and material spec is typically 7075 aluminum versus 6061
 
get an A5 rear end kit from VLTOR. technically milspec diameter tube and gives you the adjust-ability like a carbine with the recoil impulse of a A2. Their A5H2 buffer is your "middle of the road" "runs most setups" buffer weight.

$214 ? I don't think so. I'm sure it is great but this will be a budget build.

I presume rolled threads are stronger and mil spec in general is stronger? I presume your preference is Mil spec?
 
Thank you all, I ordered Mil Spec.
 
I hate the term milspec it is so confusing for people. It is also used by companies to make the product sound like it is better which I guess is my main beef with it. Kind of a false advertising thing in my mind.

bcm sells a A5 tube, end plate, castle nut, A5H0 buffer (might be too light depending on gas system) and a spring for $99.

nevermind you already ordered.
 
Doesn't commercial give you more adjustments???
and the whole this is stronger than that argument is like saying a dumptruck can hall more payload than a Tacoma...but all you are doing is grabbing 3 bags of mulch from Home Depot.....so the argument is kinda mute!

Now you're using the AVERAGE argument. Yes, MOST of us will only haul a few bags mulch from the store. Some of us will have a front end loader dump a load directly into the bed. I for one, tend to break stuff and Mil-Spec to me means maybe it has a greater chance of surviving my abuse.

Just sayin';)

I always take my quad axle dump truck to Home Depot. Just last week it was for a peice of quarter round. Plenty of room for that one stick of moulding.

I don't know how you made it home. That quarter round almost broke your truck probably. Lol

This is my whole beef with the milspec term. People think it means it is better or stronger but this is not always the case. Most of these supposed milspec parts where designed a long time ago, modern production methods, coatings and metalurgy have all come a long way since the rifle was first designed. XYZ company says their part is milspec but what milspec are they claiming to meet for that part. Is it the finish or the material it's made of or every single specification for that one part which could literally be hundreds or thousands to make it exactly like the military version. In short a company can finish their part in the same finish as a military part and call it milspec while it only meets one milspec instead of them all.
 
Mil-spec is a standard of manufacturing to ensure interoperability, commonality, reliability and cost to ease the strain on military logistics systems. There is a mil-spec standard for many items the military purchases. Ten different companies can be contracted to manufacture receiver extension tubes, but each must adhere to the mil-spec standard or they will not be accepted. The result is that a soldier can remove a component from an M4 in an arms room at JBLM, such as a butt stock, and put it on an M4 in an arms room at Bragg and the fit is the same, no issues.

Commercial receiver extensions adhere to no such standards, there are widely varying manufacturing processes, and what stock fits on one extension tube may or may not fit on another.

Pick either or, but stick with it because they do not mix. My life has been spent in and out of foxholes, so for myself there is only one choice.
