MarksmanHarry Posted January 9, 2016 Posted January 9, 2016 Right... So I'm looking at buying a G&G GR25, as I want to run a nice DMR. So I've got a few questions... - Would there be a better pick for a base gun as DMR? - I'm going to be putting a 120 spring in her, what high torque motor+torque gears should I purchase - Batteries... Should I run 8.4, 9.6 or 11v Li-Po? May add more questions as they come into my head, thanks in advance.
Supporters sp00n Posted January 9, 2016 Supporters Posted January 9, 2016 i have a G&G SR25 i have fitted a Polarstar jack to it in all honesty every guide i have read recommends getting the A&K SR25, as it has the v2.5 gearbox, which is the same as the v2, except it has a 19tooth piston and longer cylinder etc, which ensures correct cylinder porting for the longer barrel length. the main problem with the G&G is it has a propriety hop unit ... and the nozzle is huge lol the only other issue i have found is with 0.4 bb's and above not feeding in the 120rd mags, as there double stack type, 50rd and the hi-caps are fine. i did ru a 7.4v lipo, if going 11v, i recommend a mosfet, unless you like replacing trigger contacts. one last problem i had with mine, if your quick on the trigger release, you may lock the gear box, and as it has no full auto, i had to remove the motor to poke the anti reverse latch into un jamming the box. other then that its a nice gun i wont be selling mine

As for the quick trigger, if I fitted a new selector plate+programmable mosphet = backup full auto for clearing? (just a theory) Personally would you recommend me go with A+K? Thanks for the help pal Edit: I also can't find any UK online shops with the A+K SR25? I usually shop at PatrolBase

Thanks anyway pal - and I'm not too fond of m14 style rifles (cm032) EDIT: Also Mr Duck - if I'm guna go down the m4 route, what would I need to upgrade to make it into a nice DMR
Supporters Sitting Duck Posted January 9, 2016 Supporters Posted January 9, 2016 the longest barrel you can fit...... after about 350mm it does jack $hit but it looks bad ass to enemy mine is bigger than yours & no I'm not over compensating for something........ but there are limits - p90 mofo has gone ott me thinks: DMR - dmr the whole thing is kinda weird..... most guns can shoot better without the long mofo barrel or the higher fps you gain say 75fps but often without attention to detail to barrel/hop you get little over a decent normal aeg Yes you can "convert" a M4 to a "DMR" but some picky places may not accept that mofo single shot M4 as a true DMR but in effect a m130 spring, lock to semi if no auto ever available then an additional micro switch tucked away to trigger a mosfet to clear any semi lockup's - but mag needs to be removed if clearing a lock up & firing on full auto neo motor fet deans etc for response - really though it is just getting it shooting as best/accurately as you can really really messing with hop bucking barrel is where the attention to detail is..... no point shooting a heavier bb and still range and groupings being absolute $hite even with extra fps Before you embark on a M4 dmr project - check your site's specs more serious places don't allow just anybody with a beefy M4 and announce it as a dmr.... me personally and other not so serious sites couldn't care less if it is following the normal 425-450fps limit locked to semi - then fair enough to me tricky bit is getting a "dmr" to perform like a dmr ya average starter can shoot ok-ish but a poor dmr all over the place will just leave you annoyed

I was thinking of using a programmable fet so that both auto+semi shoot in semi, then like you said a micro switch in the magwell for clearing... The problems: I've never modded a gun internally, so I have NO clue on how to do any of this, or which parts to buy... All I know is I want a bad ass DMR because I was going to go down the TM VSR10 route, but tbh I think this way will be better because towards the end of the year I'll probably chuch a P* FE in it to make it even more kick-ass I also dont want to be spending LOADS, i was thinking of like 200(300 max) for the base then like 100-150 or so max on mods? Would that kind of budget be appropriate (I already have optics so only external mod i'd need/want would be a foregrip+mock sup'.
Supporters Sitting Duck Posted January 9, 2016 Supporters Posted January 9, 2016 nomally dmr's go at 425-450 max ruling 50 less than sniper's max limit due to aeg and also the dmr can spam a bit on semi true milsim strict ruling may enforce a 3 sec delay (aprox time to recock a bolt sniper) m120 spring will get you to say 400+ m130 is what you should need to attain 425-450 (though this can vary on different springs) max gearing 13:1 and a VERY good motor pulling m130 full stroke normal gen gearbox basic service etc........ however - it is barrel and more importantly the hop that you need to spend time/money on R-hop is going to be the way to go but I haven't dabbled so can't offer much advice in that area I'm still learning but have found the alternative flat hop don't work too great on tight barrels 6.02 often the longer barrels seem to go 6.05 upwards rather than tighter and higher fps but hop/bucking/nub is critical area - the box is not so must be mental mofo - working well but not ultra critical I'm on the cheap mess about side of stuff - probably with a 50m range the area you need is probably pro-win hop R-hopped on a decent barrel - not mental one but lapped and polished to close perfection - that is what the mofo's have in their guns after numerous experiments with bb's and buckings - not easy to get that close to squeezing everything out of gun just saying higher fps is not the answer to everything.... too many keep bunging in a higher spring to get the fps rather than make seals airtight bad range - more power - nope TM's shoot very well they all say but often fps wise they are lower than most guns out of box so that example proves fps is not the be all n end all many think yes you will spend most of your budget on the hop/barrel to attain max possible range/accuracy/groupings the box itself is not any area than needs loads of work - just a bit servicing and motor/fet before you go nutz - check your site is not too picky on its dmr spec and a beefy M4 is allowed to me it should be but some sites/players get a bit picky

So, being as I have a 4-9 optic, all good-in-the-hood. So...Now my questions stand at: - What base M4 should I chose - Which Hop unit+ bucking should I buy - Which barrel? - Which motor - Which gearset - Who the f*ck are mofos you keep talking about haha
Supporters Sitting Duck Posted January 9, 2016 Supporters Posted January 9, 2016 Base M4 - any one as long as take the general TM stuff 300 to 409mm I guess though a base M4 should not have the fixed front sight unless your optics are on risers though you can replace the fixed M4 front sight with fold/removable one http://www.fire-support.co.uk/product/ics-metal-cxp16-long-version-airsoft-gun-aeg nice looking gun, 2 part gearbox to allow you to go from 350 to 450 spring change can add on longer outer extension and barrel to look bad ass but say a 350 barrel in supressor will be fine.... great uk seller for ics stuff hop/barrel - hmmm avoid madbull - if spending money pdi barrel, prowin hop (though ics hop/bucking is a little bespoke and might not work in ics) motor shs torque - strength and not too silly speed gearset - well stock 18:1 should be ok at a push 16:1 or 13:1 if snappy response is plenty mofo's - just general term aka mother f*cker usually when something is damn bloody good Not saying the ics one is the be all & end all you could get krytac or others TM etc.... but tbh it might be worth two things: 1 - see what others may say - always good to research and get opinions etc.... 2 - you could just approach firesupport and get them to build your gun for you to a dmr spec (note there is a sportsline (plastic version) that is £50 cheaper but tbh get the metal for £50 more) I would of said this or that gun but the ics will allow you to swap springs yes some have a very quick change spring, but on M4's you have to half remove the gearbox unless you drill out a bloody big hole where stock tube goes to get to QD spring guide the ics - not quite as quick but lower box/wiring/motor stays put Wait a while - somebody else will chime in with other suggestions and I might even change my mind also but put on spot the long cxp might be one I'd consider then have the dmr/aeg quick spring change option - drop down to 350fps and overkill that little 12yr old $hit with his JBBG that's not taking his long range hits all morning (yes I'm a sick bastid/mofo)

MarksmanHarry Posted January 9, 2016 Author Posted January 9, 2016 Polarstar jack mate wayy cheaper then a FE, and more air efficient I have no experience with tha a&k so cannot comment mate What's the difference in the two? Apart from the 150 price difference? And whats the best place to buy one in UK bud? So if I go with polarstar jack, all id need then is the base+air rig+hop+barrel? EDIT: Done a bit of research, seems cool bit consider it tbh... but still ^
