Perfect in my Remington R-25 in .308 Winchester

by Stevey GB, Gear Expert from TX, United States Written on June 12, 2023
I have this nickel-boron BCG in my Remington R-25 in .308 Winchester. I replaced the OEM blue BCG with the TRYBE nickel-boron version since the old bolt was getting sloppy and harder to clean. This one works like a silver jackhammer into my chamber, just perfectly. This gun is pretty big as carry guns go, and the bolt of a large frame AR is a hefty chunk of steel. This BCG has a beautiful silver finish and cleans easily after an outing. This is a hunting gun mostly, and a corrosion resistant BCG lets me get by with a bit less maintenance in the field than a nitride BCG. But for a build, the less-expensive nitride bolt may be the way to go. Oiling everything before and after use makes cleaning easy, especially with any number of modern CLP liquids.
Most Helpful Positive Review Nice BCG at a Great Price
Visually, this BCG is of high quality. It has a nice uniform black semi-gloss finish that should be easier to keep clean than some of the low cost phosphate finishes. The gas key appears to be well staked, the forward assist notches engage as they should and when I disassembled it, the internal fi...

Most Helpful Negative Review Would you recommend, yes and no
First of all, this was to be used for a 6.5 creedmoor build. I checked the specs and checked online and found that this bolt carrier group should have been fine for the 6.5, so I went forward and ordered the nickel boron bcg. The barrel is a ballistic advantage 20 inch on an aero m5 upper. I chec...

Firing pin retaining pin too large

by J, Verified Owner from FL, United States Written on July 26, 2025

Pros:

  • Had to replace

Pros:
  • great finish
Cons:
  • None
Best Used for:
  • I bought these to finish up my 6.5 Creedmoor build
  • I am using this to finish up my 6.5 Primo build

Failed headspace check on .308 with brand new Ballistic Advantage barrel/Aero Precision M5 upper

by JC, Verified Owner from MS, United States Written on May 25, 2025
Would not recommend this BCG. After blowing out primers on the first three shots, I spent more money troubleshooting to find that the bolt failed the no-go gauge headspace check. Glad I lived through the test shots in the beginning. Would not recommend this bcg to anyone.
Pros:
  • Looks nice
Cons:
  • Does not function correctly
  • Looks can be deceiving
Best Used for:
  • Paperweight
Would recommend: No

Another good quality from Trybe

by Cody, Verified Owner from AZ, United States Written on May 5, 2025
Bcg is phenomenal. Used in a new build out of 277 fury barrel. Cycles well and hasn't had any wear from that high pressure

Surprised with the quality of nickle boron

by Jack-O, Verified Owner from MT, United States Written on April 1, 2025
This 308 bolt is shot peened, mpi, HPT INDIVIDUALLY (not batch tested) all the best highest grade steel on bolt and carrier. Very slippery. Tight gas system and headspaced perfectly on a go gauge. I looked up the specs on MFR site after I bought it on sale and it specs out in top tier. Totally worth it for the price.
