Framing nail gun works like new!
This was my first experience with ereplacementparts. I looked at their assessment of what was likely to be wrong with the gun. I bought all three parts for ~$17. When I took the gun apart, two of the three pieces were broken. I put in the new ones and the gun is now working great. A new gun would have cost ~$300. I'll definitely use ereplacementparts again!

Gun washer
Difficult to define the correct washer/gasket. I had to send back the first incorrect part but the second one was the charm. The photos are difficult to decipher understandably
