Normally I am very conservative when shooting an AR15 for the first time due to past experiences in breaking new builds in. This isn't a build because I purchased a PA10 lower and 308 upper complete. Both Gen2. The upper is the CHF 18 inch upper. Must be higher quantity because it costs more. Regular price $1299 on sale for $799. Got an email today that they are selling them for $999. Sorry, I will cut to the chase. Was more anxious than normal. Put a 20 round Magpul magazine with 180 gr Federal Power Shock in. The rifle shot all 20 rounds flawlessly. Very happy. Next step is accuracy. The PA10 is the real deal, at least for me.
