Trasher Posted October 9, 2008 Report Share Posted October 9, 2008 Excellent work. How easy is to cycle the bolt? (compared to the Tanaka rifles) Link to post Share on other sites
The_Racer Posted October 9, 2008 Author Report Share Posted October 9, 2008 Actually mutch harder... I had a Tanaka M24 and the DSR is more "sturdy" , nothing wobbles like my tanaka did... Link to post Share on other sites
tome Posted October 9, 2008 Report Share Posted October 9, 2008 When you say the first 2 shots never go anywhere, do you mean they are "light strikes"? Link to post Share on other sites
The_Racer Posted October 9, 2008 Author Report Share Posted October 9, 2008 I think it is from a gas overpressure... because the 1st 2 shots never go the same place... Its strange , but i had that with my old tanaka 2... i think it is gas related... Link to post Share on other sites
Dentonboy Posted October 9, 2008 Report Share Posted October 9, 2008 Can you adjust FPS? It's a little hot for my site...but I want one. Link to post Share on other sites
The_Racer Posted October 9, 2008 Author Report Share Posted October 9, 2008 i dont think it is possible , i don't see a PCU (power control unit ) anywhere... But , as you can see , Yellow gas is one of the strongest gass'es around here in belgium... Use ultra 134 gas or something and you should get around 350-370 FPS Link to post Share on other sites
AnotherJesus Posted October 9, 2008 Report Share Posted October 9, 2008 Check out the Star AW338 thread that's stickied. It's meant to be a pretty similar system. If not an exact clone. I think the power is controlled via a screw in the magazine somewhere. There's a picture guide in that thread anyway. Link to post Share on other sites
Fighting Maus Posted October 11, 2008 Report Share Posted October 11, 2008 You need to disassemble the magazines completely to access the PCU screw. It is on the back of the main gas resevoir. You need to remove the PCU screw, remove the washer/o-ring, then replace the PCU screw. Then the fps will be adjustable. Link to post Share on other sites
hessu75 Posted November 4, 2008 Report Share Posted November 4, 2008 Hey guys, I finally received my chrono. The Big Dragon 9600+. I chronoed my DSR, with the stronger hammer spring, Straight 0.43g bb´s and Yellow Gas. I fired with both mags all 22 shots. Interval was about 2-5secs, during loading. Room temperature, about 21-22 degrees of Celcius. Chrono was setup for m/s. 1st mag: 1. 128,3 2. 125 3. 124,7 4. 124,1 5. 124,1 6. 126,3 7. 126,9 8. 127,1 9. 128,1 10. 128,9 11. 129,5 12. 129,9 13. 130,7 14. 131,5 15. 130,7 16. 131,5 17. 131,5 18. 132,3 19. 132,5 20. 133,1 21. 132,5 22. 132,5 Average m/s was: 123,4. In Joules 3,25. 2nd mag: 1. 128,7 2. 128,7 3. 128,3 4. 127,5 5. 125,4 6. 125,4 7. 125,4 8. 125,4 9. 122,3 10. 123,9 11. 121,8 12. 125,2 13. 125,4 14. 126,3 15. 126,3 16. 127,3 17. 129,3 18. 127,5 19. 127,5 20. 127,1 21. 129,3 22. 130,7 Average m/s was: 126,6. In Joules 3,41. In my opinion, quite good consistency and power. I haven´t touched those PCU screws. Only the hammer spring. Give me your input peeps. Cheers -Hessu- Link to post Share on other sites
hessu75 Posted November 5, 2008 Report Share Posted November 5, 2008 Krapp, Fookedd up the first mags calculation. Correct one is: 129,2m/s. 3,58J Cheers -Hessu- Link to post Share on other sites
Noart Posted November 6, 2008 Report Share Posted November 6, 2008 why don't chrono with .20's like normal pepole? *sigh* Link to post Share on other sites
Trasher Posted November 6, 2008 Report Share Posted November 6, 2008 More reviews, skirmish reports? Anyone? How is the hopup holding "zero"? How solid is the inner/outer barrel assembly? Wobble? How the (very open) bolt design copes with dirt, leaves? Snagging on branches, ghillie suits? Skirmishing without the bipod and the sliding weight removed? Slinging the rifle?

Korppi Posted November 6, 2008 Report Share Posted November 6, 2008 why don't chrono with .20's like normal pepole? *sigh* Your suggesting that he should chrono with .2g-> oh gee 3J let's play! And then load up with .43... Link to post Share on other sites
kimkafwan Posted November 6, 2008 Report Share Posted November 6, 2008 More reviews, skirmish reports? Anyone? How is the hopup holding "zero"? zero? could you explain pls? How solid is the inner/outer barrel assembly? Wobble? The outer is good but easy to scratch. The inner is well built. How the (very open) bolt design copes with dirt, leaves? Easy to dirt but also to clean. Snagging on branches, ghillie suits? Skirmishing without the bipod and the sliding weight removed? It's better without the bipod i'm using this: ugly but faster to use. Slinging the rifle? http://www.france-airsoft.fr/forum/index.p...howtopic=102244 Link to post Share on other sites

Libris Posted November 6, 2008 Report Share Posted November 6, 2008 Your suggesting that he should chrono with .2g-> oh gee 3J let's play! And then load up with .43... I don't get your point here? It's 3J with .2g or .43g Link to post Share on other sites
Wupjak Posted November 6, 2008 Report Share Posted November 6, 2008 Your suggesting that he should chrono with .2g-> oh gee 3J let's play! And then load up with .43... Ummm. Anyway, good write up. Thank you for taking the time to do that. If you have the opportunity, could you please chrono with .25 or .20? That'll give us a better understanding of velocities relative to other rifles of the same category. Link to post Share on other sites
Sale Posted November 7, 2008 Report Share Posted November 7, 2008 I don't get your point here? It's 3J with .2g or .43g No it's not. Ever heard of energy creep? It's especially pronounced with gas rifles. Using heavier BBs increases the muzzle energy, so airsoft guns should be chronoed with the BBs actually used in the game. For reference, some velocities with 0.2g BBs would be nice, though. -Sale Link to post Share on other sites
hessu75 Posted November 7, 2008 Report Share Posted November 7, 2008 I am a normal person Normal person in my opinion will choro his/ hers rifle with those bb´s he/ she is about to use with that particular rifle. Here are ten shots with other mag with 0.2g bb, yellow gas and 21 Celcius in house. Measurement is calculated with m/s and using the same Big Dragon 9600+ chrono: 1. 193 2. 195,2 3. 195,1 4. 197,3 5. 196,7 6. 197,1 7. 196,8 8. 201,2 kaboom! 9. 198,7 10. 197,5 I totally agree with my fellow finnish countryman ( ex-patriot dude) Sale, the 0.43g bb will give totally different results and is to my liking than this playing around with lightweight bb´s, which will not be used while skirmishing with this DSR. If you calculate these results, you will notice totally different Joule result. Even I can see it, and I did not even calculate very throughly. It´s about 4 Joules with 0.2g. I don´t care about 0.2g results though. Also, the consistency is not the same as with 0.43g bb. The power is all over the place. Not good. I am fabbing up lighter hammer springs now, and will test those too, so that I can get the rifle to finnish 3 Joule standard. 3J is the max output of semi firing weapons here.

Bldr.dh Posted November 20, 2008 Report Share Posted November 20, 2008 Sorry for the random, off-topic question but I don't suppose you could measure the width of the upper receiver for me, could you? Link to post Share on other sites
TTSupra Posted April 3, 2009 Report Share Posted April 3, 2009 Great review and tests! On the Aw338 page the gun was tested at 90m. Can someone test it at a longer range? I am debating which gun to get the DSR-1 or the AW338 and I could use some advice. Which one is more accurate / better gun? Thanks! Link to post Share on other sites
Hammerfall Posted April 4, 2009 Report Share Posted April 4, 2009 Neither will shoot 90m... but then again not many airsoft snipers rifles can. I'd personally get the version 2 DSR over the 338. Link to post Share on other sites
climber Posted June 17, 2009 Report Share Posted June 17, 2009 how far as i can see the dsr-1 and aw338 use the same internals...???? if there is any differences it becouse they have many lemons...=) Link to post Share on other sites
The Chef Posted June 17, 2009 Report Share Posted June 17, 2009 Virtually the same. The hop system is very similar although the housing is different. The nozzle system is practically the same, although the DSR-1 bolt is a bit back to front (bull pup). The mag system is the same. As for Lemon rate... I'm not quite so sure. Both my AW338 and DSR-1 have suffered the same issues. Low power in stock form, and terrible consistency. Now there aren't really that many factors to contend with in a gas gun. Gas Route, Gas Seal, Valve Efficiency. It uses an AEG style hop, and they can be pretty reliable, so you can almost discount that.... Hey ho, Gas guns... you gotta love 'em!
