PS90 HD Bolt Rate Reducers.

Post by panzermk2 » 19 Mar 2012, 11:29

Ok kids I have the a prototype in my hand made from the tungsten material. They are heavier, this proto by almost a ounce.

The issue is cost. They will not be cheap due materiel, what it takes to machine this materiel and low production count. Cost will be around $120.00 to $130.00 each.


The PS90 was designed first as the P90 with a 10.5 inch barrel. It is a blow back carbine. When FNH stuck a 16.5 barrel on the P90, made it semi and called it the PS90 they did NOTHING to the back/bolt end. With the increase in barrel length it means the bullet is in the barrel longer but the bolt cycles like it still has a 10.5 barrel. FNH was being lazy and cheap by not doing anything with the back end. Because of this some PS90's even using loads well below cartridge max have issues with popping mags, miss feeds and other issues.

By increasing the weight of the reducer we are compensating for the timing change of the longer PS90 barrel.




I want to gauge interest in it before even taking pre-orders so I don't have a repeat of the 650 shell plate.

A little information is requested. I guess I understand that the added mass slows the bolt cycling after firing, but what is (are) the advantage(s) of this?

I'd be in for one.

Add this on top of the upgraded springs and I think you'd have a nice insurance buffer with handloads :)

Great job Jay! Did you use HD17 grade material? That puts you at about 1oz increase based on calculations for a square unit - so you hit it spot on!

I also would like one, along with your zoot recoil springs for the PS90.

Just hold my hand and help me navigate the maze on how to pay for the goodies....... :o)

Thank you, Sweet Chuckie
