Helpful Positive Review good affordable carrier by M, Verified Owner, April 1, 2025
Used this for a recent build. It seems nice and everything is within spec. The price is near impossible to beat. I'm happy with it. Great for any build that just needs 'a carrier' so to speak.

Helpful Positive Review Trybe bolt by Bob, Verified Owner, May 17, 2023
Works as it should. Product does not come oiled. Only 300 rds fired. No problems so far. Does look nice and slides in real nice. Only time will tell if the coating will hold. Will update after 1000 rds.

Helpful Positive Review Functional with style in all flavors by Stevey GB, June 2, 2023
I use TRYBE BCG's in several builds. All have been perfect, and the finishes enhance some of my builds cosmetically also. My current favorite is built around a Helix 6 barrel in .223 Wylde. Gorgeous polished BCG surface shines like a jewel. Love the...
