Most Helpful Positive Review BCG color and firing
I found that its great the only thing is that the color gets scratch and color will remove and i feel that they need to find a paint that will be able to with stand the heat because if not the pain removing will certainly bother you
Most Helpful Negative Review "Lifetime Guarantee" against chipped coating? Came with coating already chipped
Received the FTD colored bolt carrier, looks new, but might of been test fired. There are multiple spots where the coating has chipped off where the BCG meets the upper receiver. Either I was sent a defective product on purpose, or the QC people at WMD or Optics Planet need glasses. Will be returnin...

Great product after I got a replacement

by Jay, Verified Owner from WI, United States Written on August 29, 2025
My first bcg came without an extractor on the bolt face. I returned it to OP and received another. I love the cobalt gray color over the Nickel Boron.
Pros:
  • Came highly recommended
Cons:
  • Possible Quality Control issues

OD (Money) Green

by MidwesternAR, Verified Owner from KS, United States Written on July 15, 2024
As with any color matching from online products, the OD green is less of a dark OD green like most industry AR products and more of a lighter, money green tone. Still looks awesome. Otherwise looks well-machined. Nice, shiny nickel.

A better option

by Luis M Ortiz Garcia, Verified Owner from NJ, United States Written on January 20, 2024
Nickle boron w/ ceramic top coat BGC runs smoother and are easier to clean than the phosphate ones. Just 2 drop of oil on the gas rights and you're good to go. I took it apart before anything just to give it a wipe down that was all.
Would recommend: Yes

Smooth operating...

by Luis M Ortiz Garcia, Verified Owner from NJ, United States Written on January 13, 2024
This Nickle boron slide is smooth, if you get some type of color one like I did(FDE), it's supposed to come one where ever it making contact. Shot 200 round 556 and no paint came off yet. I used 2 to 3 drop of lubrication for the piston rings and that was all.
Pros:
  • Smooth, easy to clean
Cons:
  • none yet
Would recommend: Yes

looking promising

by LeeG, Verified Owner from WI, United States Written on December 2, 2023
Came in looking promising, I haven’t shot it yet but color look great with my gun. Try to research prior buying but didn’t see much reviews but it was a decent price. So I decide to give it a try. I like the color varieties.

DO NOT GET A PAINTED ONE

by PKP, Verified Owner from OR, United States Written on September 18, 2023
The actually bolt may be ok but the Paint is Horrible! Don't Waste your money or the time it will take you to clean the paint out of your gun! I put the Bolt in stock Colt .223, it never fed correctly, always bound up and the paint chipped off everywhere it came into contact with anything else!
Best Used for:
  • The trash
Would recommend: No
