Is the barrel length the same between the standard MK3 and the HC ver? Anyone with chrono data? Thanks.
TX 200 and TX 200HC barrel length
- Thread starter Soloshot
- Start date
According to an AA email the barrel length of the Pro Sport, TX standard & HC are all the same @ 9.5''. That is the useable barrel length and not the shroud.

So then there should be no MV difference if same spring is used between the 2 models? Assuming all other variables are held constant.

There is a tall order ... Bore specs change this figure more than most realize. Piston seal and well how well the lock up is at breech seal also shift power around more than most realize.
just sharing ...

These are the variables I am suggesting to hold constant. If so the muzzle velocity will be the same on all 3 models?

The rifle barrel length is longer. The Pro-Sport and HC have the shorter, 9.5” barrels. I’ve measured all of them with shrouds removed. I’ve also purchased new barrels direct from the UK, back when they were shipped with shrouds unglued. I can assure you that the rifle barrel is longer.

Well, We have conflicting answers to a simple question! I am just trying to determine the barrel length (under the shroud) for these springers.

If they are different lengths then Air Arms themselves do not know what they are producing or at least the person that answered my email doesn't. I emailed them January 2021 and asked specifically about the TX200/HC & PS barrel lengths, their reply was;
"The technical department has advised that yes it is the same".
That email is all I have to go by, I have not had any shrouds off to measure...

DualMagMike,
The AA reply seems to say same length barrel betwee HC and PS, which is agreed to by all. The remaining bit being "is TX200 MK3 rifle barrel longer than HC and PS"?

You're not reading it correctly TBH, I asked them if ALL 3 barrel lengths were the same. I clipped things down to be quick. The full question I asked was were ALL 3 barrel lengths the same (TX & HC & PS) The response was as noted above, "The technical department has advised that yes it is the same".

I wanted to post this with my reply above. Here is one of my TX200 “rifle” barrels. Breech to muzzle on internal barrel is 13”+
I’ve also had both PS and HC barrel assemblies apart, but can’t seem to locate my pictures. But the barrels on both of them are identical at about 9.5” from breech to muzzle of barrel only. Some of the info posted on the specs online have been incorrect.

An opinion from 1 person on a phone, whether he "asked the tech department" or not. How often have people seen such information be incorrect?

. Information from an actual owner who has had both barrels in question. I'd go with this before an opinion off the phone. JMO.

Thank you Nitrocrushr, exactly what I was looking for. The tx200 rifle barrel is about 4 inches longer than hc and ps versions. Now the tough part, I have to wait for a tx200 to become available, both the hc and ps are in stock but the full rifle version is out of stock
