sam beach WSW Posted January 13, 2020 Share Posted January 13, 2020 So I have a APS Demolition rifle that i am converting to a DMR I have done all the internal upgrades and its pushing 450 FPS. But I need to figure out how to semi lock my rifle before I go to Jackal 5. because DMR rifle must not be able to use full auto. If anyone could help me with this that would be amazing.

Steveocee Posted January 13, 2020 Share Posted January 13, 2020 I think you're forgetting the more important factor in that it's not legal if you can do full auto and it's over 370FPS. The simplest way is to put a physical item in the way of the fire selector, small nut and bolt to stop it turning that far around, otherwise if there is a programmable mosfet in there that would be a great way of doing it as well.

Moderators Tackle Posted January 13, 2020 Moderators Share Posted January 13, 2020 Some sites won't accept just a physical block on the selector switch, as full auto can still be triggered (as a fault). if it's an AR platform then you can modify the selector bar on the exterior of the gearbox .

Skara Posted January 13, 2020 Share Posted January 13, 2020 File down a tiny (1mm by 1mm) square on the selector plate AND jb weld/screw a bolt in the receiver. Luke (Negative Airsoft) has a couple of videos on locking guns to semi, check his work on Youtube Link to comment Share on other sites More sharing options...
PureSilver Posted January 13, 2020 Share Posted January 13, 2020 Just trim a bit off the selector plate. No ugly irreversible external modifications, gun won't go into full auto, no problem. A better solution is a programmable FCU, especially because there will be times you want to be able to go into full-auto (e.g. to resolve a semi-auto lockup, which is even more common in guns with strong springs, like DMRs). If you don't already have at least a MOSFET, which you absolutely must, now is a good time to fit one that can be programmed to have semi-auto only in any fire selector position.

An FCU isn't a mechanical lock though. Needs to be irreversible (without taking the whole gun apart). Link to comment Share on other sites More sharing options...
E21A Posted January 13, 2020 Share Posted January 13, 2020 Modifying the selector plate is the only “proper” way Link to comment Share on other sites More sharing options...

What do you suggest for @sam beach WSW's need to be able to clear jams by reverting to full auto, or cycle completion without the ability to select full-auto? Maybe a German-market FCU with cycle completion but without full-auto, like this Gate? Link to comment Share on other sites More sharing options...
