Amazing product - Primary Weapons Systems MK114 MOD 1-M .223 Wylde, 14.5in bbl Upper Receiver

Ordered this upper from opticsplanet and PWS mod 1 lower from a different site. Surprisingly, ordering the upper and lower separately cost almost $300 less than purchasing the rifle as a whole.
As for fit and function I am very surprised how smooth shooting this rifle is. As my first experience with a "gas piston" AR and reading how much more recoil they produce, I haven't found it to be true with this rifle. My other AR is a standard DI with a 16" barrel and it has more noticeable recoil than the PWS. The 14.5" barrel provides more accuracy than I am capable of. Smooth, accurate and reliable. Just an all around great rifle. The only thing I would change is the barrel material. I prefer a chrome lined barrel. Just a personal preference.
