My goal is to have more consistent shoots on 70-80 m
currently i am reaching them no problem and with little wind i can shoot down a can of beer on 73 m with 3-4 shoots.
also im having trouble zeroing it in sometimes (i think its the scope tho).
on a non-little wind situation my shoots are perfect till they reach 60 m
after that they go in a clockwise spiral making me think its ether the barrel or the bucking. I can make a video to make it more clear and run some more test if needed (i have 0.43,0.48,0.50 but i dont like to use the 50 because they are grey so i shoot with 0.48. All of them are made by BLS).

my setup: Vsr10 G-spec
trigger: springer custom works budget s-trigger
piston: springer custom works 90° piston and spring
cylinder: stock JG one
cylinder head: stock JG one
hop up: AA hop up
bucking: Mr hop 70°
nub: modify flat nub (looking to put the panthera inside but dont will it change a lot)
barrel: PDI Raven 6.01mm 360mm(it was 430 and bridged stock but i removed the bridge and cut it down for the cylinder/barrel ratio, its 3.3:1 now)
spring: laylax pss 170 (i have the 190 too)
I have some costume made aluminium spacers too

Im open to change some parts inside to make it better or to do diy on it.

hi

if you are able to hit can of beer on 73 m , then what else you expect from airsoft gun ??? dont touch anything as you will make it worse LOL

 

[dominik549]

I like round number more... so 80m would be nice.
Well i if someone has any advice to achive a litlle bit more acuracy or any experiments I will try them out

I would suggest an EdGi stainless barrel and a professional R-hop and Masada arm from Shapeways, but I don't know if it will be all that much better than what you have.
I suggest 6.00X410mm for you with your outer barrel completely full of barrel spacers to get the maximum accuracy and efficiency.
Besides that, upgrade your cylinder?
It could have minor air seal issues that could cause inconsistency due to varied velocities.
If you are really paranoid you could sort your ammo on a really sensitive scale like I did once and also polish it in a special tumbler.
It worked quite well but it was too much work for results that I didn't need.

The airseal is perfect on the cylinder but a better cylinder for a better glide is in the soon future. I have my eyes on the 6.00 barrel for a time now, i think it would be a good upgrade and i didnt clean my bbs at all but i plan to clean them for the next play.the arm im kinda stuck on the panthera one and the panthera nubs but the Rhop sounds nice. Tnx for the advice!!

Btw my cylinder head to the hop chamber airseal is not so great any info for that ?

change to an autobot 75 degree since it gives you better air seal and it's stiffer for such a strong spring. I might even go with 80 degrees. You can also, use a 430mm barrel and mod a fake suppressor or even a real one to fit your longer barrel that comes out of the outer barrel.

good thing i have the autobot 75 in reserve so tomorrow i will test it out, for the barrel i would not go too long since i cut it to 370(because of the ratio) i have seen much improvement in the range. I will post the results tomorrow side by side comparison autobot vs mr hop. thanks for the help!!!

Good luck! I'll be interested to see the results

You are really at your max. The 410mm inner barrel may give you a few more fps which more energy will help with accuracy. Also, if you go with a 6.00mm, then I would try a 420-430mm since there is less air loss.
I don't think that anything else you do will improve the accuracy.
I doubt changing your cylinder will improve accuracy but may make it smoother. I am also currently running a JG cylinder (I have used many cylinders over the years). JG's are good value for money. It is a pity JG does not sell their cylinders separately. JG should consider selling them as they would sell a lot.

I bet that within 75mm+- you won't have any issues besides lost power, and I feel that piston weight kind of affects barrel ratio, so it's really hard to tell.
As for the cylinder, you can actually get them from AirsoftPro but you may as well buy an AA or something else if the shipping is too expensive depending on where you live.

 

[dominik549]

tomorrow i will do couple of tests

1. 48.g vs 50g
2. washed 48.g vs non washed 48.g
3. a laylax 170 (current spring) vs laylax 190 (i will probably cut it a little or make the 170 harder to have more little more fps)
4. autobot vs mr. hop

Don't worry about washing them. That was done back in the day when heavy bb's seemed to have a powdery film on them. Now the don't. Especially BLS.

I still wash mine, occasionally polish mine, and rarely sort mine by weight even though I use BLS.
I also wash and sometimes polish my .28s and .32s and I see a more noticeable change as they aren't nearly as good.
When I polish I mix the BBs with 4.5mm airgun BBs and shake them in a bottle with a little bit of water for a movie or two, then I simply wash them and put them on a towel to dry them.
I suggest it if you have some particularly bad BBs or are just curious but it really does work.

thanks everyone for helping and ideas the gun is now super precise at 73m and can reach more than 80m no problems because of your help.
Ive added some bearings on the spring guide and washers to add to the fps a little changed the bucking to the autobot so the air seal is perfect(tested) (i didn't know mr hop has such a bad air seal and i had the 70° autobot im gonna order the 75° one later) I washed the bbs but it is noticeable in only non windy situations and the 50.g bbs are more consistent but i cant see them so whats the point.
here are the results of the 4 hour long testing :

0.48 vs 0.50
if we ignore that the 50. are grey (big disadvantage) and focus only on consistancy and range i can say that 10/10 50. hit their mark (10cm circle) on 50m no problem while the 48. hit it 8/10 and are noticeable moved by stronger winds but not by too much maybe a 10cm to the side.

washed vs not washed
as we all know this is for the perfectionists and it works, the consistency of the washed bbs is better but not much better and i would suggest to wash them only if you find yourself in tricky situations where you can barley see the target a lot
the results show that in 50m target scatter of nonwashed is 5cm+-
the washed scatter on the 50m target is 2.5+- (first time i hit multiple times in the same spot for a long range target)

harder spring vs softer spring
i wish i had more springs in this range and if someone knows for a spring that is between laylax 170 and 190 strengths please let me know.
the 190 is much more consistent and longer range hitting targets at 70m+ in a straight line (i had to lower the hop significantly)
the 170 is a winner after all because the 190 is very very stiff and i dont see myself having pain in my wrist all day playing airsoft. the range is lower the consistency also but if you set the hop perfectly you can see very similar results.

autobot vs mr hop
this one surprised me a lot because i was more a mr hop guy (the test go little bit in the autobot favor because its brand new).the autobot has a better seal (you can see by the naked eye the nozzle hole is smaller) the shots were also better and the autobot could hop much more then the mr hop its only finicky with the adjusting but when you set it up its dead on point unlike the mr hop which had a weird arc for me.

Glad it's working!!!
I do suggest that you just stick with the 70° as it will most definitely give you better results.
