What bits in a VSR upgrade make the most difference in consistency?

Recommended Posts

I've bought a Well MB03 that I intend to upgrade and I'd like to know how far I really need to go to get something usable. I'm fairly convinced that going for an Action Army hop chamber and a Maple Leaf Autobot bucking will be the majority of the improvement.

 

Is upgrading the barrel actually important? I get mixed messages on this and the availability and expense of a VSR inner barrel is such that I'd quite like to skip it. Also is there any point upgrading the trigger assembly, cylinder, piston and spring if the stock FPS is pretty close to field limit already and the thing doesn't slam fire or otherwise break when you use it?

Triggers get upgrades for reliability as at high fps they fail over time, also gives a better trigger pull and bolt catch

 

vsr g-spec comes with 303mm barrel that people report gives poor consistancy and joule creep. So most change that out for a 430mm barrel to fix this.

Try using the search tool, 3 character minimum length, and read through the results.  For example, "mb03" returns this:

I did but this doesn't answer the question. I'm not looking to find out what I can upgrade and with what because I already know this through searching. What I'm trying to ascertain is what has the most impact; from what I've read, it seems like trigger adds nothing unless it's not firing properly, and people are undecided whether barrel makes a significant difference.

The biggest thing you can do for consistency is eliminate air leaks. A mate has a maple leaf bucking and 6.03 barrel in a vsr and its a monster, consistant and accurate.

I’ve found air leaks can make FPS consistency bad and the barrel helps the most with shot placement consistency.

I would say a good cylinder head, barrel and hop bucking would be best for consistency - it's all about the air seals. I run a 6.02 barrel in mine, maple bucking and airsoft pro rounded cylinder head with o-ring seal. Also PTFE taped the bucking to the barrel just to be extra certain.

Cylinder head, bucking and barrel for conistency.

 

trigger for longevity and reliability 

 

everything else because you can bro

Consistency of what?

Shot placement, range, fps?

 

In an airsoft gun all the above will inter-twine with each other. 

 

The thing most airsofters forget is that in reality, most airsofters can't actually shoot. For the small gains that can be made in shot to shot consistency by upgrading you could gain more by learning simple techniques like trigger operation and consistent aim and hold.

 

Things like lightening trigger pull and correctly spacing inner barrels would help shot to shot consistency, but also things like marking hop settings and ensuring your ammunition is consistent and clean will make potentially big differences. 

 

If you're asking what to upgrade to make it more skirmishable, hop bucking and barrel are your best start points. Save triggers etc until they fail (as they will).
