Most Helpful Positive Review PWS is the only manufacture that I'll happily spend $1k on for an AR platform.
Simply fantastic weapons. I will trust my life to PWS system every time. Piston is amazing, soft shooting, simply amazing guns. MOD 2 is definitely worth it at the price. Better build overall and lighter.

Incredible quality - obvious attention to detail

by JM, Verified Owner from NJ, United States Written on March 17, 2024
PWS needs no endorsement from me, but the quality out of the box is obvious. Wipe down the assembly oil and the quality of the anodizing and forging is obvious. Wanted something ideal for suppression that would be super reliable with minimal fuss and dirt. Haven't tested accuracy yet but it shoots super flat and zeroing with a red dot was very easy. The 16" length and PWS compensator results in almost zero rise. There is a somewhat distinct recoil impulse but it doesn't move the rifle around.
Pros:
  • High quality
  • shoots flat
  • Easy accessory mounting
  • Stays clean
  • Easy recoil
Cons:
  • ?
Best Used for:
  • Any situation needing a reliable, easy shooting, easy-to-clean option.

Merry Xmas to me

by Jesse, Verified Owner from TX, United States Written on December 21, 2023
Couldn't be happier with my purchase amazing craftsmanship light weight. Went weeks deciding between the Mod 1 and this one. In the end and with great discounts only found throught Optics Planet I went with this Mod 2. A little more but well worth it.

Shoots great, loves good .223

by wmaguire, from ID, United States Written on June 4, 2023
Just built a rifle with this upper last week. Took it to the range to try out a variety of 5.56 and .223. As advertised, the POI was identical between the two. The big surprise was accuracy. Recoil with the 5.56 was noticeably more, and the groups spread out quite a bit. Then I loaded some .223. Suddenly I was shooting through the same hole at the same range. I zeroed it for 50, and at that distance the groups were sub-MOA. All in all a fine upper, but I think it likes .223 a lot better.
Would recommend: Yes
