Hello... I'm brand new to this or any forum... But I have a practically new ps90. My Son and I have been to the range 1 time. Approx. 20/25 rds. have been fired thru it. I used FN blue tip ammo. We went back this past Sunday and when it came time to shoot it would not fire?! I cleaned gun before and after as instructed after we shot? The only thing different is I bought a cheaper ammo AE ?! I tried several diff. Rounds and none would fire?! I even tried blue tip and it wouldn't fire either?! I took it home cleaned, lubed, etc. Nothing?! Any help would be Greatly appreciated!! Jay

Was the firing pin striking the primers? If not it Sounds like the firing pin may be the issue.

Are the rounds cambering normally? Have you checked the condition of the firing pin?

Welcome to the forum by the way!

Yes Sir it's defiantly clambering the round. When I pull the charging handle back it shoots the un-shot bullet out normal spot? I don't see any marks on the primers? I don't know my way around this guns internals like firing pin, bcg, etc. I was wanting to take a look at the firing pin but honestly don't know how to get to it?

Hello and welcome!

sorry to hear your woes on a brand new rifle.
Yes, your firing pin is failing to strike the primer.

Disassemble it again and begin with the trigger. Make sure the trigger bar rails are seated correctly in their channels.
Look at the the trigger it self and work it back and forth. Check that it is connected to the wire bar correctly. Work the trigger back and forth to see if the trigger bar is also moving back and forth with the full range of each trigger pull.

Then move to the hammer pack.
Look over all the seers and make sure they are in good order and move freely as they operate. Watch out for the hammer coming forward hard. Don't let it swing up hard agains the other parts as you work the seers to test their operation.
Now focus on the hammer. Make sure that the hammer will release correctly when you work the seer to release it. Again, don't let the hammer swing up hard against the other parts.

Now look at the movement group (bolt group). Look at the firing pin and make sure there are no obstructions visibily holding it back. Make sure the pin striking face of the pin is in good shape.

Reassemble and function check the rifle making sure everything works including the safety in on and also off positions.
Leith the safety off you should hear the hammer release and drop with thioe pull of the trigger.

Now take a snap cap if you have one of an empty brass shell and dry fire with the snap cap or empty brass in the firing chamber.
Check the snap cap or spent brass where the pin is supposed to strike.
What you are looking for is a new mark the pin should make with that dry firing.

Just went through something similar with my new PS90. A round had fired and ejected as normal but unknown to me was the neck and shoulder had separated and had stuck in the chamber causing new rounds to not fully chamber. This caused the sear to not fully release the hammer, you could hear the hammer snap forward but it was only going part way due to the sear preventing full forward travel. Check your chamber carefully, verify that a round fully chambers with the action out of the stock.

Primer /brass piece stuck in firing pin channel, or separate neck of cartridge lodged in chamber..

Good thought. I didn't think of this one because I have never had a neck separation ever before from any caliber, even when firing hot loaded rounds.
