How do i upgrade my Bar-10 to 500fps?

Slight slip up there biguk - you need to get to the equivalent power of 500fps with .2g BBs (2.32J) using 0.25/0.28g BBs.

I was just going by the information found on the link below

I found this link:

but im still pretty clueless about it:

I have assumed, so this post could so not be helpful , but you ensure the FPS with .2g BBs, and then if you are firing with .25s then the equivelent power (joules) will be OK - the 2.32 mentioned. No?

Well like i said i dont mind if i have to use .2g bb's. I use .25g in my Garand. and that fires beautifully. But if the Fps is too much with them then .2g it is.

Just would like someone to say...buy this..this this and this and you'll get this..Also want to make sure it doesn't break on me.

Heard the word's laylax mentioned alot.

No, I don't think you get it.

The fps limit is always measured with .20g bbs. It doesn't matter what gun it is, that's what you measure the fps with, always.

Once you've got the fps with .20g bbs to a legal limit, then you are free to use any bb weight you like for the actual gameplay.

I believe there is a couple of quick things you can do to up the FPS on the BAR 10 with putting much extra stress on the internals. The first is trimming the nozzle to increase the airflow. The second is something to do with taping the cylinder to improve the seal. I don't know eachly as I've not done it but there is more info if you search the other forums. That put it up to about 450-460 I think. Beyond that you're better off spending your cash on a new barrel & hop unit if you want to improve the performance.

Yes, that's right Wladek.
Still, bigUK needs to know what bits and bobs he needs to upgrade a Bar-10 and I have no idea - just pointing out that 500fps @ 0.28g will be way off the scale of acceptable usage. It would need to be 422fps max with 0.28g

Incidentally, those that use bolties seem to go for higher weights than that anyway!

Yeah i get it...i know Fps is always measured using .20g BB's. So i MUST be legal with them.

I wont be carrying about the upgrade, myself im paying wolf or Airsoft amouries to do it for me.

BB's aren't a concern at the moment. I can try various one's after the upgrade to find what suits me. SO aslong as it fires near 500fps with .2g after the upgrade then im happy.

Wolf or AA? Coward! Still, I only have to pick up a screwdriver and the gun falls to bits so probably a good idea. (Heh, you have at least one good gunsmith in Dog Co though!)

Yeah true. Unfortunatly he has a house to finish. I dont trust myself with taking gearbox's apart with being shown what to do first. First time i did i knackered my ICS M4.

The cost of paying someone to upgrade out weigh's the emotional turmoil of breaking a £400 gun.

You can get a BAR10 to near 500fps surprisingly cheaply and easily, anyone can do it. If you're going to do it, I suggest you upgrade the trigger sears as well. All you need to do with a BAR10 to get 470fps+ is cut the airbrake, teflon tape the cylinder head, fit a nineball hop rubber and teflon tape the hop to barrel seal.

However, if you have aspirations to be a "sniper", I suggest a PDI 6.01 tightbore barrel and the following Laylax PSS10 parts as well - piston, piston head, bearing spring guide and cylinder head. Not cheap but you need consistency and consistency costs money. Out and out power is not necessary to be an effective sniper, I've got 2 rifles based on BAR/VSR 10's, an Enfield running at 490fps and a Mosin Nagant running at 400fps. The Mosin is every bit as accurate as the Enfield, because I can use SGM .29's in it, so don't make a noob "sniper" mistake by thinking you have to have 500fps.

Thanks..for that.. I've heard Laylax mentioned alot when it comes to barrels. Im guessing PDI is just as good.

You'll find the Laylax PSS10 parts more easily available in the UK. Fire Support regularly restock them. The PDI 6.01 barrel is an awesome bit of kit (I should bloody think so, the money they cost!). I got my barrel from Redwolf, if I recall.

Once you've got the rifle put together, that's when the hard work begins really. The hop needs bedding in, you need to find the optimum bb weight and the hop setting for the weapon and then stick with it. You'll need to zero your sights and become familiar with how the rifle performs in different wind conditions, leading a moving target, etc. You need a consistent rifle to be able to do this. Add onto this learning to judge distance, how to stalk a target, how to shoot properly, how to conceal yourself and how to observe, then you're going to be busy for a while!

Yeah im looking forward to the challenge. Its something i've thought about for a while. Been a rifleman for a while now.

When the Springfield from MGW came about i jumped at the chance. It'll mean alot of practise but i'll get there.

Hi, Ive got to be honest, BAR10 straight out of the box, shoots 400 something, .28 or .29SGM and it is great.

Try it before you start spending and tinkering as the extra FPS does not mean extra distance and certainly not better consistency (AKA as accuracy). Hop spin and no axial spin on the bb seems to be the key.

You'll need to zero your sights

What's the best way to do that?

Without getting too technical - Setup an A6 target (or tape 4 A4 sheets together) 30 metres away, with a 1" black square in the centre of it. Get in a good prone, supported firing position and fire 5 rounds at the bottom centre of this square, concentrating on your breathing and shot release. Next, look at where your shots have fallen and find the centre of this group, this is referred to as the Mean Point of Impact (MPI). Next, adjust your sights to bring them up to the bottom centre of the square, this is referred to as the Correct Zeroing Point (CZP). Don't forget that with an airsoft weapon, your hop setting can have a big effect as well, so get that set properly as well, with an ammo weight you're happy with and can stick with.

Next, go back to your 30 metre point and fire another 5 rounds at the CZP. Check your MPI again and adjust accordingly, repeat if necessary. I'd then recommend repeating the process at 40 metres (you should be able to use a single A4 sheet now). When zeroed at 40M, you'll know that a 30M shot will strike higher than your crosshairs and at 50M+, your shots will be a little lower, allowing you to compensate by aiming off slightly at longer ranges.

I could type pages of marksmanship, grouping, zeroing and sniping info but I don't want to bore anyone!

Thanks Pete. I'd actually find pages of that stuff pretty interesting.

I'm one of the many people here who have absolutely no military training so all this is extremely useful. You should think about running a CiA Sniper School (maybe spell it Skool to get the young 'uns interested ).

Funny you should mention that.....
