5 Stars - DISREGARD OTHER REVIEW!

by BattleBuilt, Verified Owner from MI, United States Written on March 26, 2025
I recently purchased the LWRCI ICA5 Upper Receiver from OpticsPlanet, and I couldn’t be happier with my experience.

OpticsPlanet makes the process easy, and their prices, deals, and overall customer service and benefits make it a no-brainer.

If you create an account and use their app, you get access to special discounts, OP Bucks, and other offers that make every purchase worthwhile.

Now onto the product itself—I bought this upper to match my LWRCI ICM6 ambi lower, and the result is nothing short of incredible. This is hands down the best AR setup I own! The quality and craftsmanship of LWRCI parts truly stand out.

Just a heads-up to anyone browsing reviews: please disregard any comments about the Direct Impingement (DI) vs. Short Stroke Gas Piston confusion. That was just a minor typo in the product listing and has nothing to do with the quality of this upper receiver. For the record, this is indeed the Short Stroke Gas Piston version, not DI.

Overall, both the ICA5 upper and my experience with OpticsPlanet were great as usual!
Pros:
  • Everything
Cons:
  • nothing
Best Used for:
  • Suppresed AR's

Direct impingement????

by al, Verified Owner from MN, United States Written on September 28, 2024
There's a lack of vision with this upper
The description says it's a direct impingement but it is not, it is a piston driven upper which is what I wanted? So i'm happy, but there's just a lot of confusion!!!
