The Receiver Modifications will enable you to change the way that your weapon shoots ammo in Starfield. Some receiver mods can turn the humble pistol into machine gun-esque weapons by changing the way your gun reacts to a trigger pull. This page will detail all the Receiver mods that you can unlock and we’ll also give a detailed breakdown of every Receiver Modification, their crafting cost and the research required. These particular modifications will only become available to players who have 3 to 4 skill points in Weapon Engineering, so they’re definitely geared toward experienced weapon modifiers!

Best Receiver Mods in Starfield - Pros and Cons¶

It’s worth bearing in mind that the Receiver mods that change the way that your weapon shoots are a pretty late-game modification as you’re gonna need to put a bunch of points into Weapon Engineering. So, whilst these receiver mods are pretty powerful, you’re gonna have to do a lot to actually unlock them. You can find weapons out in the wild with specific receiver mods, so if you’re not looking to get deep into Weapon Modifying, your best bet might be to keep an eye out for rare modified weapons. The best way to do this is to head out and explore randomly generated camps and buildings on various planets!

Below, we’ve listed some of the best weapon receiver mods, but it’s important to also highlight that these receiver mods are not best suited to certain weapon types, even if they are in the compatible weapons list.

Burst Fire¶

If you don’t wanna get to Weapon Mods 2, then Burst Fire can be a pretty powerful option from the first tier of Receiver modifications. It’ll fire two rounds per trigger pull. It doesn’t have that many compatible weapons but it does work quite well with a high fire rate weapon like the Grendel and Drum Beat rifles. It could also be a good modification for pistols as well, like the Eon and the Va’ruun Starshard.

Fully Automatic¶

The Fully Automatic receiver means that as long as you’re holding down the trigger, the weapon will shoot ammo continuously. It’s worth mentioning that it will not increase fire rate - so don’t expect your pistol or shot gun to become a crazy machine gun anytime soon. In fact, this modification is best suited to the Rifle and pistol weapons that already have a quicker fire rate. You could try it out on the shotguns and pistols with lower fire rates but it might feel a bit clunky and counter-intuitive.

Binary Trigger¶

The Binary Trigger is a pretty cool upgrade as it essentially means you fire two rounds each time you pull the trigger (the second shot is released when you release the trigger) - a bit like the Burst Fire mod. This is a mod geared towards pistols and because it essentially shoots two shots with one trigger pull it can feel as though it’s increased your fire rate! Rather than go for the Fully Automatic weapon mod on your pistols, try this one out for size!
