Hi I'm building my first AR pistol looking for a good decent upper I'm thinking 7 or 10 inch also what type of buffers should I be running on both models?
Any advise would def. greatly appreciated Thank You!

If you wait PSA might have their 10.5" upper for $350 again in a few weeks. I've had a 10.5" and ran it with a Spikes ST-2T buffer and it worked great.

I use carbine spring and buffer for 7.5" and 10".

7.5" with heavy buffer on my new build.

Put a 100 rounds through it yesterday with no issues.

Thanks! I've heard the 7inch uppers are pretty touchy when it comes to reliability...any feed back on that???
