Most Helpful Positive Review Great quality.
I bought this kit to have a spare for my "AR14" rifles. These parts are well made and chrome plating was top notch. I would not hesitate to buy again. I checked all the dimensions and all were in spec. Great buy �

BCG upgrade parts

by Aaron, Verified Owner from FL, United States Written on August 7, 2024
Nice chrome plated cam pin and firing pin. Oe pieces were wearing. Cam pin had grooves worn pretty bad. Cheap insurance to buy a more durable part! Should replace BCA pieces right out of the box. Ask me how a firing gets all grooved up after like 100 rds...

Enhance your BCG.

by OGB, Verified Owner from FL, United States Written on September 17, 2023
I used this set to upgrade and enhance my old and worn-out BCG. Parts are mil-spec and fit perfectly. Finish is nice and smooth. Highly recommended for an upgrade for a standard BCG or for a new budget build.

Milspec- or "How I Learned to Stop Worrying And Love Quality Components from BCM, Colt, or ST"

by LyingProphet, Verified Owner from FL, United States Written on July 2, 2023
Tried popping these into an 8920 milspec carrier as part of my 300 AAC build. The cam pin and firing pin went in as expected but the cotter pin was incredibly fussy. Tried just about everything short of hammering it in to get it to fit. Still wouldn't budge.

Swapped out the cotter pin to a different carrier and it refused to get set in place. Tried using a BCM cotter pin with the Obsidian Arms firing pin in the new BCG - didn't work.

In frustration, I removed the Obsidian Arms components and replaced them with identifiably milspec BCM equivalents. Worked like a charm. While a mildly fascinating exploration in more affordably priced parts from an unknown brand, they are functionally useless.
Pros:
  • Affordable
Cons:
  • Grossly out of spec
Best Used for:
  • being returned
Would recommend: No

by ChuckwagEn63, Verified Owner from WA, United States Written on February 28, 2023

quality parts

by LetsGoBrandon, Verified Owner from MN, United States Written on July 6, 2022
Good quality back up parts. Always good to have on hand. I frequently hit the range and if anything is gonna break, usually its the firing pin or extractor that goes first. Least in my experience. So having spares is always good.

7.62x39 build must have!

by Jon Galla, Verified Owner from FL, United States Written on October 10, 2021
I built a AR47 and have tried a few BCG’s but have been using these parts with all of them. The chrome finish has been great and super easy to wipe clean and the firing pin has been flawless with both brass and steel cased ammo. Let’s be honest if you build a AR47 your building it to shoot cheap Russian steel ammo and these parts have been 100% reliable! I would highly recommend them for any ar15 platform.
Pros:
  • High quality
  • reliability
  • great finish
  • Afffordable
  • Ease of cleaning
Cons:
  • None so far
Best Used for:
  • AR-47
