Why are blowbacks "low end"?

[emumikey]

I understand what you are saying... but take the difference between a ball and an egg

If the outside of the egg fits at 10 and will not break until 9 you might shoot the design to be 9.5 +/- .5.

If you have a ball - ie less likely to break, say to 8 it allows you to design to 9 +/- 1. A great tolerance usually means cheaper to build.

yeah, we were trying to say the same thing!

but you would always design for the zero (9 with the ball, ten with the egg, whatever)
The +/- would be the acceptable deviation for design. If it fell out of that region, it would be rejected.

"Low end" blowbacks are designed with this so called slop you all speak of. Even if each part is built precisely to +/- 0 of the given part spec , there is excessive play between matching parts in the manner that allows the marker to fire under almost all conditions. Dirty , poor maintainence , dried geletin etc. They also always very large bore barrels for the same reason , fire any paintball in any condition if at all possible. The added benefit for our discussion here is that the manufacturing process is now allowed greater variance over parts considered to be acceptable but outside the ideal spec for said part. This is manufacturers allowable "tolerance" for any given part or assembly. I won't get into 'stacked' tolerances and it's variables other than it falls under the same guidelines only for a given assembly. The Automag , for example , is ALL about stacked tolerance.

The given firearm examples are done precisely for the reason , historically , Military weaponry has been design with that mindset.

So.....

The question and the my response to said question is that 'if' a blowback style marker was built to the overall specs considered to be more or less standard for the average 'high end' marker , using similar materials , components and craftmanship it's performance could and should IMO easily meet and exceed the given acceptable level of performance of more commonly accepted High end marker and thus ( your in for it when that word comes out ) it would most defintely be considered a High End Marker.

Of course to sell it to anyone on PBN you'd have to call it something cool like a. . .

Oh nozoorzzzz!!! You stole my idea Jay. Now i'm going to jump off of a bridge.

You know jay, i've seen at least a decent part of your paintball collection and you have well over 10k in markers alone las time i saw. What's with the huge rush to make more profit???

It's a service I provide really , teaching newb e ballers the value , or the lack there of , of an e dollar.

Good point. Has anyone seen the marketing the Proto Matrix Rail? They rant about "dual durometer" materials throughout the gun. All this essentially is is two different types of rubber glued together.
