DMR suggestions & Cost to lock an AEG to Semi

[tyrael]

I'm new back to airsoft and after going skirmishing recently I think I'd really like to build out a DMR. Does anybody know the approximate costs to do this?

Ideally I want to be able to push as close to 450fps as possible, are there any somewhat affordable options out there?

 

I was thinking of the KRYTAC Trident MK3 SPR-M but cost wise this is a bit more than I wanted to go. Is a CYMA SR25 with upgrades going to perform better than krytac?

I also liked the look of G&G TR80

How much do you have in the bank? It could costs you around £100 or £1,000 depending upon how far you want to take it (just want to hit the DMR power limits with an AEG, build a great electric DMR, or maybe bite the bullet and just buy an MTW and go HPA).

A simple spring swap will do this, however if you want accuracy at range and consistency (and an electric RIF that survives the punishment) you'll need to do more work.

Unless you're playing milsim games your "DMR" does not have to look like a real steel / world one, use whatever platform you want that makes you happy (with the right setup an MK 23 pistol, or an AAP-01, could be classed as a "DMR").

I was thinking ideally like all in perhaps £500 really I suppose for the gun and any upgrades to it. Would additional things would need to go in to ensure range and consistency that can take the battering? 

 

I've seen an affordable gun that apparently is 380-420fps, I suppose with the cost I could probably put some decent updates on it

Alternatively this CYMA, I just don't really understand the MOSFET/Programmable part Kestrel Basic ETU... How easy is it to lock to semi? If I have to get somebody to do it, is it easy? It states:
 https://www.patrolbase.co.uk/cyma-platinum-cm-097-m4-ar-15-aeg-kestrel-basic-etu?pv=27636

or this SR25 from CYMA but I suppose I'd prefer the other given more accessible mags  https://www.patrolbase.co.uk/cyma-cm-098-sr-25-dmr-aeg-kestrel-basic-etu?srsltid=AfmBOoqa_vgG9z8Q5TuTAepPr_DSt2a9wBAv94m0Zgh3jBw2eka-g-Lu

I also loved this, but again not sure how much it would cost to lock to semi https://www.patrolbase.co.uk/krytac-trident-mk3-spr-m-aeg?pv=27270

 

I've actually just seen this, which looks really good - good cost and within budget with some upgrades perhaps and pre-locked so I don't need to mess around changing fire modes

I built my AEG DMR around a used LCT G3 as I wanted a gun that looked like it should be a DMR so 7.62 or .308 but that was my choice. 
 

Original plan was to all out motor, mosfet etc etc but it really hasn’t needed it yet. Had a Maple Leaf 6.02 barrel and 4uantum hop and nub for accuracy and a modified (shorted) m130 spring to make it shoot exactly 450 fps on .2’s. Had the selector plate modified so it won’t go full auto. 
 

I have stuck to .32’s as I like to lay down fire and anything heavier gets significantly more expensive. 

 

Gun was £280 used and the mods were around £100 with a local tech.

 

Not sure how long it will last without the motor and MOSFET but it’s great fun to shoot and very accurate.  
 

You will need to budget for a good secondary to cover the 25/30m MED.

Don't forget to factor in the 'kewl' bits for a DMR... scope, bi-pod, and kit you'll need like a decent battery & charger, mags, BB's and kit to wear and carry mags etc...

A lot of rif's are great out of the box so save upgrades until they're needed.

Not sure about many other sites but my local site classes all rifs as select fire unless it's a bolt action and max fps for non bolt actions is 360 so your 450 fps might be an issue.

Thanks I'll check this about what they class as DMR! Definitely will need some kewl factor haha

That's not too bad, I just found two I like, about £70 price difference but once is locked mechanically semi and the other MOSFET semi, so can be taken auto. I'll check locally what's allowed but perhaps the extra monery on the mechanical lock could be better, just in case

There is a Mk12 in the classifieds worth a look.

If I was doing it, I'd just get a Cyma platinum SR-25, a power appropriate spring, a ZCI m4 hop unit (the stock one has a weird arm, or at least mine did) and a quantum hop rubber. Setting them to semi-only isn't too difficult, though if you don't know what you're doing I'd get a good tech to do it, and the larger cylinder volume can be helpful for setting it up efficiently on heavier ammo. Quick change spring system is very useful for going to different sites or events that may have different power limits, and you won't have anyone saying "that's not a real DMR" at events that require real-world DMR platforms.

Thank you! This is really helpful

Do you have any experience with East Crane? In the event I can't get an in stock CYMA by the time I get my ukara

Unfortunately I do not. I'm more of a gas gun person, so my experience with AEGs is limited

East Crane/E&C make some decent kit. They were the original OEM for Specna Arms and are still OEM for a number of manufacturers, as well as their own stuff.

 

As far as DMR mods go, the reason why most people suggest an SR25 or similar is that they have a V2.5/"V2 long" gearbox - ie one with a longer piston stroke, which means they can cope with the volume requirements of a longer barrel. With more modern hop designs the reliance on long barrels for accuracy has diminished somewhat so the two E&C guns you've listed start to come into their own, despite only having a standard V2 gearbox. I personally have a MK12 which runs around 420fps with an E&C gearbox perfectly fine.

 

This is the usual resource for advice on building an AEG DMR https://www.airsoftsniperforum.com/threads/the-holy-grail-of-building-your-dmr-aeg.892/ so go have a read.

I'd second this. In fact, it's exactly what I did (albeit with a maple leaf rubber). No need to take it to a tech to semi lock though - the Cyma SR25 is about as easy as it gets to semi-lock - you simply need to put a couple of washers onto the rear body pin, such that they are sandwiched between the inner face of the receiver and the outer face (left hand side) of the gearbox. This is enough to stop the rearward movement of the selector plate so that it can't move into the full auto position. SR25 mags are cheap, and easy to get. The Battleaxe ones with the fake bullet window work excellently in the Cyma SR25, and hold an obscene number of BBs.
