SCAR 17S will not fire

2026 Views 8 Replies 4 Participants Last post by  JonM
I bought my Scar 17s 9 months ago. I took it out to the range and would not fire. Firing pin left a light imprint on the primer of the round. I took it back to the dealer and they told me packing grease was not allowing it to fully punch the primer. So, it sat in my safe for many months and I took it out to run some ammo through it and could not have any enjoyment because it would not fire again.Any Suggestions?

Clean the firing pin, bolt, bolt carrier and firing pin of shipping grease.
Did you run a pipe cleaner through the firing pin channel in the bolt??

With the bolt pushed to the rear the pin should protrude a bit out of the bolt face when the pin is pushed forward.

Improperly sized brass on handloads can cause light strikes in any gun.
Take outbtge firing pin retaining pin and recheck it may have been assembled improperly. The firing pin should be installed with the bolt full forward and the bolt cam pin in and the hole in the cam pin aligned with the rear of the carrier and face of the bolt to allow the firing pin to go full forward. Once the bolt is extended with the firing pin in place insert tge firing pin retaining pin in the rear portion of the carrier. It should not be flush but just slightly raised. If it goes in full flush easily its misding the retaining oring or the ringbis damaged. Do not use anything but finger pressure to insert the retaining pin as it can possibly bind the firing pin if excess force is used.

The bolt and firing pin should move freely by tilting the carrier. If it does not it needs to be properly lubed. Stay away from frog lube it clogs firearms especially in cold weather.
