Recently, I've been using a 2j dmr build on aeg with 0.3g bbs but like to change out the springs regularly on the same aegto turn it into a 1.1j aeg build. I use a overvolumed setup (a full cylinder with a 363mm barrel and a 16tooth 16:1 gearset). Will this stress out my gearset too much if the shimming is fine as I like to semi auto spam my dmr due to the overvoluming as I am worried that my 2j setup will damage my gearset if I swap the full cylinder and m120 out to a ported cylinder with a shs m135 spring.

Uh? The sites you're playing at don't have a "one in the air at a time" rule for DMRs/bolt action?

The point of that and semi-locking (besided the law) is so you don't pepper someone with a barrage of 2j hits.

The two main sites i play at would ban you for that shit. 😕

Are you in the UK?
Is your rifle locked to semi only when you are running it at 2J?
Do you semi auto spam it at 2J?

Are the answers to those questions:
Yes
No
Yes?

If they are, you would be breaking the rules at (hopefully) every site in the UK and potentially admitting to a criminal offence.

I don't think trigger spam at semi auto is a criminal offense as there's no rate of fire to the law about section 5 firearms outside of it must be single shot. Could still get in trouble with the police though if the officers mistake the semi auto spam for full auto if it's fast enough, and I think there's probably something to be said about the spirit of the law vs the wording of the law.

The post is still... well, I think other people have pointed it all out already 😂

I wasn’t stating that it was; the law is quite clear about defining full auto.

That part of my comment came in the “breaking site rules” category.
 
All the sites I frequent, DMR is limited 1.88J, but requires physically disabling the full auto. Get asked whenever chronoing how it's locked, too.

Using a MOSFET to limit to semi-auto is technically a grey area, I guess, as it's easily changed to enable full-auto and thus is still technically full-auto capable.

Its kinda one of those odd areas because I have seen people fire a semiauto just as fast as a full auto RIF. It's all in the... Finger action? :ROFLMAO:

It isn’t a grey area. As the gun is still capable of shooting full auto, the law limits it to 1.3J. I explained this to a site owner, who very quickly changed his site rules to require physical locking.

I wish more sites did this... And if you can't answer how your gun is semi-locked, then maybe you shouldn't be using it.

I don't like this as an option either, and as @Colin Allen said above, it's not a grey area as it's still full-auto capable; most are just a quick switcheroo that you can do in game, by your car in the safe zone, or even just in a bluetooth app on your phone.

I'll avoid getting on my soapbox too much, as DMRs are both my favourite way to play but also something that I have huge criticisms on how they're managed and how people tend to play them. I basically treat them like semi-auto sniper rifles, and so I play it exactly the same way I play my bolt actions. I am firmly of the belief that DMRs should be physically semi-locked to the point where you need to take it apart and replace parts to get it back to full-auto. I see so many DMRs today because it's so easy to do with a simple MOSFET, and I hate to say but I think most people who run them have the same outlook as the original poster here. The amount of DMR trigger spam I see across different sites is astounding, and I'm not even that set on the "1 in the air" rule; DMRs are nuanced. Too nuanced for a lot of airsofters it seems 😅

I can't speak for all sites but the ones i've been to usually have a "one in the air at a time" rule for this reason.

I think RIFT allow DMRs up to 2.3j with this rule as essentially it's no different to a bolt action if you're following the rule.

My two DMRs are mechanically locked, my 417 has the selector plate cut so it can't lift the cutoff lever and my SCAR SSR has a bolt through the trigger cam to limit its movement to semi only.

But law aside, the spirit of the game is still "Don't be a dick" and looks like the OP isn't sticking to it. 😕

My statement about the grey area was referring to sites that don't require a physical lock to be installed. I've attended a few sites that allow a MOSFET-only lock, but technically, that's not compliant, as the gun remains capable of firing in full-auto mode. They use the grey zone to not require the physical lock, which is wrong.

I wasn't suggesting that using a MOSFET lock alone is acceptable; I just wanted to clarify that I'm fully in favour of physical locking. Reading my original comment back, I can see how it may have come across as supporting MOFET is fine lol.

:)

I wonder where the law stands* in regards to semi-locking by mosfet? Because while that's in place it's "technically" semi-only. Much like a full-auto GBB on the limit on green gas, is only a refill with red/black away from being full-auto-capable above 1.3j. My Sig 553 will shoot over 4j on CO2 with the standard (non-NPAS) nozzle fitted, and the semi lock only needs one receiver pin removed to swap position.

*(probably a total grey area, in the same way a knife is only a knife until you kill someone with it, at which point it becomes a murder weapon.)

Almost certainly a grey area or at least it's enforced as a grey area, especially I don't think mosfets were part of the discussion when the Firearms Act or Section 5 legislation were written up. I'd imagine the law stands based on how an airsoft RIF is set and used at the time over what it's technically capable of. I base my guess on the matter of fact that distributors/wholesalers often import hot AEGs and swap the spring so they are legal and site-legal.

Like your example with your Sig, my Noveske N4 was way too hot with the standard nozzle on green gas when it came to me from the retailer.

Some sites with a requirement for a physical semi lock may be held to it for their insurance policy as well as their own choice to reduce the opportunity to abuse the perks of running a DMR.

the Firearms Act or Section 5
These are not the most relevant legislation. The Policing and Crime Act 2017 sets the limits and defines what full auto is. In these situations, if the gun can easily be made to shoot in full auto, which usually means anything that does not involve disassembly, it is classified as being capable of full auto.
