Madbull DD SA80 Handguard Dimensions

Instead of starting a new topic I may as well add to this one.

6.01mm Madbull Tightbore

or

6.03 Madbull Tightbore

Same website, at 509mm, is only a £3 difference (£39 and £36 respectively)

So, why get .03 when you can get .01?

Cheers,

Liam

 
Sorry, didn't see this!

The "which bore is best" debate is almost everlasting.

The consensus seems to be that 6.03 is the best, 6.01 is held in disregard because people say they get jammed up because obviously, they're a tighter fit around the BB.

But then there's the "expensive" upgrade parts companies, that tend to market 6.08 as their most accurate barrels and there's also barrels you can get which are rifled.

I use a 6.01 in my L85 and I've used 6.03 and the rifled "twist" barrels too. 6.01 gives by far the best performance. Greater range and accuracy than the others if all other things are equal.

The reports of them jamming seem to be a load of bollocks, I've never had a BB jam with mine and I've never cleaned it or anything. Just use good quality BBs that have been polished... Which practically all have apart from those misshapen shite ones from Skegness that are obviously dodgy lol.

Only downside can also be considered an upside. Due to the tighter bore, they up your fps by around 30, which can take you over your site limit in some cases.

But on the flip side, this means you can use a spring less powerful, which means you'll get a better rate of fire, a quicker trigger response and it'll also increase the life of your gun's internals by a small fraction due to the lower strain of the spring meaning your motor and gears don't have to work as hard to turn the mechanism over.

As for the barrel brand, Madbull barrels are perfectly fine and reasonably priced. The Black Python V2 6.03s seem to pop up everywhere and everyone and their mums have got them fitted in their guns.

Mine is a Madbull V1 455mm long 6.01 diameter one though. I would have a 509mm, but I initially bought the barrel for an M4 project and it ended up being about an inch too long, so I tried it in the L85 and decided to keep it in there. Only about £30 too.

Well Ed,

You have thrown a spanner in the works there a little. I was dead set on the 6.03mm Madbull for that jamming reason alone, but if you haven't had any problems then why not eh?

As for the L85 project, been away on holiday so its slowed a little. I decided that I prefer SUSAT's to ACOG's ten fold so sourced a second hand one of them which is being fitted today.

Also sourced a real steel Handguard which should be delivered by the end of the week, just been paid too...So might go a little crazy! I'll get some photos on when she is done!

Probably worth mentioning that if your rifle isn't a Star or Ares, the real handguard probably wont fit unless you mod it in some way or another. I'm pretty confident that the other makes (AA/ICS/WE/G&G) have their handguards attach in a different ways to the RS/Ares/Star. I'm sure Airsoft-Ed will probably know for definite and can clarify.

 
I can't report on the Army L85's compatibility with the real steel hand guards, but I know that the Madbull RIS hand guard fits on the Army, so the real one most likely won't without some degree of modification.

How much modification? I can't say, but there's bound to be some info online about it somewhere, or RR01 might know.

I might be wrong, it might just go straight on with no issues at all.
