Most Helpful Positive Review Best of the Best

Most Helpful Negative Review Machining issues on outside of the receiver
Overall the upper looks nice but either the forging for the upper had an issue or a machine made a mistake but there is a 1" "dent" machined and finished over on the side of the receiver. Everything else looks good, but at the price paid, this isn't acceptable. If it's sold as a blem, it will be a g...

LWRCI are masters at the craft

by AWP, Verified Owner from SC, United States Written on November 6, 2025
LWRC makes the highest quality uppers on the market, very few companies match the quality, fit and finish of an LWRC rifle and optics planet is the best place to buy one. No where else on the internet is selling this upper at this price, if you were to buy this from LWRC directly it would cost you about 200 dollars more.

The features on this thing are simply unmatched, LWRC's handguards are fully freefloat, they dont even make contact with the barrel nut because of their proprietary receiver extension meaning you wont be able to replace this handguard with anything else on the market but you would never want to because this gives you M-lok all the way down the barrel (unlike most of LWRC's other offerings that usually terminate about 6in from the muzzle).

I have been amazed with the accuracy of this barrel and the "keyless" BCG has the nicest Nickle boron treatments ive seen. This is an upper that will due to it's spiral cut hybrid profile hammer forged barrel will probably last a lifetime (they start out with heavy barrels and spiral cut them to a custom profile that is basically a government profile barrel with more material) It's also fairly light weight, weighs less than my super duty upper for roughly the same price.

If you can snag one of these during a restock i would say you should jump all over this. NOTHING comes close to this quality for the price and i dont think you would regret this purchase. IMO this really is a "buy once cry once" upper.
Pros:
  • Sprial fluted
  • Cold hammer forged
  • Nickle boron bcg
  • Monolithic reciver extension
  • keyless bcg
Cons:
  • Propritary handgaurds
Best Used for:
  • Competition Shooting
  • Duty Rifle Builds
