I have seen plenty of p90 selectors for sale... I want one for looks on my sbr. Hammer pack is gen 3. Can I put the selector on and be ok with no ill effects? Tried to search for the answer but couldn't find it.

The one in the link PersuitSS linked makes a very nice looking safety switch. It defo fits the bill for looks and doesn't cost $100.

Aside from that, if you must have one that can move to all three positions (it will only be semi auto just like said already), you will have to order the $100 one.
Nobody makes an aftermarket one that can move to all three positions.

The best mod that gets you closest to looking like a P90 is to pay the Form1 tax stamp and SBR it.
You will enjoy that look much more than a three position safety switch

I once talked to the ATF about using an M16 BC in my AR.

They were very polite and helpful. The law is that the rifle may not fire more than 1 shot per trigger pull. As long as it doesn't, you are reasonably good to go. However:

1. They discourage you to have auto parts in there on the basis that a failure of a part that makes you full auto leaves you with an illegal weapon. The rationale is that the fewer auto parts you have, the less likely of having an accidental full auto. This was advice, not the law.
2. Looking like full auto can draw a lot of extra attention that you may not want.
3. The exact basis for interpretation is beyond me, but if you are semi auto, but just barely, and the conversion is easy, there is something called 'constructive intent', where you get busted for looking like you intended to go there.

Don't take this as legal advice.

Mine is an sbr... that is why I want the look of the 3 position selector. The one for sale in the thread for 45.00. Doesn't appear to be available anymore? I don't mind paying the 100.00 and nothing in the trigger pack has or will ever be messed with. I don't see where the intent onaling it full auto would be if I don't posses all the necessary parts and the gun only fires in semi auto.

Gen 3 trigger(hammer) pack is semisuto only.
So are the Gen 1 and 2 packs.
All trigger pack generations offered on all PS90s will only work in semisuto mode.
You are okay with a Gen 3 pack

That is all I will say because the rules of this website is very clear:
any talk of making a firearm that breaks existing laws is prohibited.

My know. But my intent is to only say the PS90 is semiauto only no matter the generation of the trigger pack.
I don't mean to say anything more or imply anything more.

OP, I just did a quick check online for the safety switches and only the FNH OEM P90 three position switch is there.
From this, I sm hazarding to say the $100 option is the only option.
Three position switch + your Gen 3 pack = semiauto only on both firing positions.

It's your rifle and is completely legal but, I have to agree with the individuals that it draws unwanted attention. I can attest to the unwanted attention part. I went to my local range with my HK UMP conversion with full auto lower(It was semi though) and the owner was a former police officer and I wound up spending an hour explaining how it was legal and showing him parts diagrams on my iPhone. PITA. Luckily I was able to get a FBI lower (Sage/Semi) and sold the other one. Though the P90 F/A selector is not really seen like a black HK UMP with bright red bullets.

Stryker Enterprises makes a PS90 safety switch that looks like the P90 one. It's reasonably priced.

A real P90 switch will not make your PS90 go full auto. One note the trigger will move further rearward in the auto position, again will not fire auto.

It's a waste to spend 100 dollars or more for the real thing.

It is not going to add any more attention than the SBR will IMHO. This is like saying that an AR15 lower with the FA engraved on the receiver selector will garner any more attention than a receiver without the FA engraved on it. Or for that matter, an 80% lower that is cut to M16 specs.

Just so long as you do not modify the hammer pack you will be fine.

While I am cautious, I'll de damned if fear of the ATF will dictate how my firearms are fitted with accessories, as long as they are legal.

Better hide that P90 laser installed on the PS90 lower as that will attract undue attention as well.

^^^^^THIS!!!!

The rifle is legal so no matter what cosmetics are on the PS90 to make it look like a P90 has absolutely no bearing on if it is illegal or breaking any BATFE regulations.

You are not breaking any laws and/or regs so screw all that stepping around eggshells BS.

If charged, and since the P90 selector doesn't affect the ability of a PS trigger pack to operate in a fully automatic state, kinda doubtful.

Speaking of IF's: If 'manipulation' by the ATF were something to worry about, each and every owner of a Gen1 or Gen2 trigger pack is a potential felon even without possessing a bitsy piece of plastic.




Who was it that applied zip ties(r) and duct tape, the owner or the ATF?
Give me a few screws a plate and some steel and I can turn a lever action .30-30 full automatic.

Feel free to do as you wish, as you will be responsible for your actions.

Interesting you should mention the possession of said hammer packs, as not too long ago there was an individual with one, a PS90 SBR, a video camera, and a you tube account who did cross over into that area. He hasn't been seen here on FNF in quite some time.

One last bit of insight. FNF is open to all members, including but not limited to agents of the BATFE.

For the record, Stryker Enterprises will not be supplying you with a few screws a plate and some steel so you can convert a .30-30 lever action into a machine gun.

There is a lot of good information in this thread and some sage advice. Unfortunately, the ATF/FTB is well known for saying one thing in a determination then changing their minds (there are multiple threads on this alone) days or even years later. While it's legal to put a functioning 3 position selector switch in a PS90, some over zelous FED or even local authority may/will take issue with it and make your life difficult for you. This is what many are saying by indicating not to go there.

I have no issues going toe to toe with anyone about this and understand that others are not comfortable doing the same. If you choose to mod your PS90 to NEAR P90 configuration, that is fine but make sure your ducks are in a row and be prepared to educate those who should know in the first place.

I don't need a switch that goes to the "A" position simply because it has a red A on it. This is another 2 second mod should I desire to do so on a regular selector switch and use a stencil set to put an A on it, should I desire to do so. For those that want the real P90 selector for their PS90, I say go for it, but be sure that you are willing to go toe to toe and can justify your stance.

I never go any place with an NFA item without my binder of approved forms and multitude of determination letters. This is why I am willing to go toe to toe. Make sure you can CYA at all times.

Hell I remember when John Norrell was welding M-16 receivers back together (back when dewatting by band saw was legal)

He would weld up the auto disconnect hole and area refinish it and sell it as a SEMI M-16 lower receiver. Was it legal? Hell yes and BATF didn't like it one bit.

But its one thing to make a VISUAL clone and a whole different thing to start installing parts from a select fire Title II weapon into a semi.

I've worked with BATF Enforcement in the past, I wouldn't want them looking over my shoulder (or serving a Warrant on me at 03:00)

These are so broad statements that you can be tallking about a 50 caliber machine gun.

and a whole different thing to start installing parts from a select fire Title II weapon into a semi.
There are so many parts that are used on both the PS90 and P90 that I am sure that the installation of a P90 barrel has nothing to do with making the PS90 a machine gun and THAT piece did come off of a Title II firearm.

Be more specific. Is the installation of the PS90 Selector Switch that has been modified to go to the A fire position that will not change the firearm from a semi automatic firearm to an automatic firearm against the law or not?

You know, if I'm putting M16 parts in an AR15 I deserve to have them looking over my shoulder, but they just get to look, because I will never have an unregistered machine gun.

We are not talking about a M16/AR15. We are talking about a PS90 that has a plastic switch that has no operational value what-so-ever in making the PS90 a machine gun.

I sure can't find anything about this in the NFA handbook or any determination letters that I have seen or any one has produced. But this is OK because I know that deep in Federal Law, you can actually charge a ham sandwich with the crime of murder. Whether it is convicted is a whole 'nother story.
