Range question

Hey guys, I am still a little lost on this range thing and wanted everyone's opinion. So obviously Im new to airsoft. I have been deciding on my first gun for weeks now and Im pretty sure I found it. But I still keep getting mixed opinions on distance. Some people tell me I could get a gun with shorter barrel and upgrade to 400fps (my field limit) and have it shoot just as far as a longer barrel gun. This dosnt make much sense to me but if its the case then I am going to buy a shorter fun instead. I was looking at the sr10 by KWA, I live in the states so no clear gun or whatever it is. I would want to shoot 150-200 ft if i can get more then I would be thrilled. I know that accuracy isnt super possible at that range but oh well. Also at closer distances, consistent accuracy would be nice too.

It is generally agreed upon that a longer and tighter barrel will allow the bb to accelerate to a higher velocity with less turbulence and thus allow you to get a more accurate shot at range. However this is also dependent on other factors such as the cylinder porting and head as well as the general air seal and hop up type.

Sufficed to say, if you want to improve accuracy at range your best bet is to use a slightly heavier bb of good quality. Such as a .28

Cheers

Also, don't expect accurate fire beyond 200 feet without a monumental amount of tweaking and a substantial investment.

You will be consistant at close ranges with any quality weapon, and yes a good set up can yeild radical results with a short barrel but a good set up can be an elusive goal. I run a m110 spring and a 363mm at 6.03mm Tight/Narrow barrel. That said, I just use your average kids baseball field as a mental picture as I play. The analogy is that I can hit out of the park but not by much. Not a great idea but I used to constantly drop bbs 20-30ft in front of my target X(

With whatever setup the mechbox is in, you will get a bit more distance with a longer barrel. Like mention before, the bb will have more time in a longer barrel thus shooting the bb farther. With the exact mechbox but using a shorter barrel, the bb's will spend less time within the barrel so that will reduce distance. It won't make much of a difference if you're comparing an M4A1 to and M16 barrel. You will notice it with a cqb compare to an m16 barrel. Just my $0.02.

Thanks for the quick answers. So I will go with the SR10, I hope they are reliable lol. What upgrades should I look at? Also what are the best Bio BBs? We have to use biodegradable at my field.

The "best" that is a heavily opinionated question. A question that is better suited to the local players at your field. Since everyone at your field has to use BIO BBs it would be best to ask locally.

Why try to change or fix something that is not broken? Why upgrade initially? Especially since you don't know what you want. Its best to simply use your AEG for now until you become comfortable with it and understand what you require to change in order for it to suit your needs better. Play with it now so you can learn what you need to change later.

Heard good things of Bioval BBB but there are some rumors going around they can crack glass and stuff and may be banned at your field.

As for range, keep it at 380 or so, 400 is a LIMIT not a GOAL. If you shoot hot at chrono then you're gun will be benched for the day and you'll have to rent or use a loaner. Not such a big deal there as I'm sure other players have 2 or 3 guns and can lend you one as a loaner.

To get the maximum range a good hop up, rubber and spacer is what you want. It will do much better than some long barreled clone shooting 400 FPS.

Final words I have to say, upgrade the PLAYER not the gun. You can rock a crapsoft from Crappy Tire or Wally World and still be competitive. You just have to outsmart the other players and be extra sneaky. I've been shot with a $5 springer before when we were playing defend the base. Guy snuck up around and when I popped my head out to check for enemies (I knew someone was sneaking around) got shot in the shoulder.

I understand that player is more then anything. While using shitty rentals I am successfully able to strategically kill most of the other team. But if I can create an unfair advantage by having a gun that shoots a little better then Im going to do that also.

About the upgrades, I have the money to get whatever, but I can get a discount on my first order. So I want to order as much as possible with that order to save some cash. I know I will want a 6.01mm inner and the other parts listed above. I am not putting them in right away however, I will use them after several times of using the stock gun. I also was curious abut an H nub, how much do they improve the accuracy? My field has a 400fps limit for full auto, but I can go over that and use semi. I would prefer to get my gun shooting just under that at the chrono with .25gs.


Last there has to be Bio BBs that stick out among all the others. Im looking for consistency.

Then you want BB Bastards

FPS + Hop up(Setting) + BB = Range

whether short barreled or longer barreled does not affect the range. This is grade 10 physics, when a BB leaves the barrel, it has no memory of where it left from.

a 400FPS gun with 200mm barrel is the same as 400FPS gun with 500mm long barrel range wise.

I believe that you don't want a 6.01 then, I was told that 6.03 is probably what you'll want because of some reason or another (anyone back me up on this?), the only time you should use a 6.01 is a BA or semi rifle.

BB Bastard also makes a Bio BB now so check them out as well as the Bioval BBB. Who knows maybe you can even become a regional Bastard.

Also depending on the brand of gun you get it might be a wise idea to purchase a correctly ported cylinder as some companies just use a non ported cylinder on all their lineup.

Finally, 400 FPS they mean on .20g BB's. Really they should say 1.41 Joules MAX but 400 FPS (using .20g BB's) is much more easily understood by the general public.

I recommend Prometheus Barrels, their 6.03 but they are some of the best barrels on the market in my opinion.

According to the review listed here on another website along with information I found on other websites like the KWA home site.

http://www.airsoftforum.com/board/KWA-SR10-t164817.html
http://www.kwausa.com/products_sr10.html

In stock form the KWA SR10 outputs between 380- 390FPS with a 0.20g BB and has a stock 6.05mm barrel. Change the existing barrel to a Prometheus barrel and perhaps swap out the hopup for something to match the FPS in that range. I think that should put you in the 400 area that you're looking for.

If you wanted an output of under 400 with a .25, you could swap the spring for Prometheus MS120SP. Which should put you somewhere in the 425-430FPS with a 0.2g. Its hard to give an exact number but it should put you around 380FPS with a .25g.

My previous comment about asking local people who play on your field still stands..

I don't agree with you at all.

I've made a 250 FPS gun that drastically our ranged most 380+ FPS guns.

It's all about tight compression and consistency along with selecting the proper hop-up rubber to your target FPS

I am talking about maximum range

please explain the science behind how tight compression and consistency will give you more maximum range.

Tight compression = more FPS + consistent FPS. So it is more FPS.

Consistency = consistent FPS which I don't see how it can increase maximum range.

The hop-up effect eliminates the whole "SHOOT AS FAST AND HARD SO IT'LL GO FURTHER BEFORE GRAVITY MAKES IT DROP" ideology here.

If you're gun is putting the proper amount of air (every time) down the barrel the BB will be riding on the same air every time, people with major air leaks or an inconsistent sealing piston head will not have sufficient air to push the BB out of the barrel properly so there's a chance it'll contact the barrel and greatly effect range/accuracy.

It's similar to someone using a MP5K cylinder in a M16 length barrel (as an extreme example)
