Nickle Boron carrier group
I'm building two somewhat higher end AR's. I'm sure these bolts are going to be the right option.

works great. I'd give it 5 stars but the cost was a bit high.

Didn’t work in my colt
Works in other lowers but not my colt not sure of the upper at this time

Very smooth bolt!
Very smooth bolt! Second and 8th round I fired through it jammed (probably bad rounds or just a breaking in period) Since I’ve not had a jam in over 500 rounds.

nICKEL bORON CARRIER GROUP
I've got one of these in my 350 Legend and wanted one for my 5.56. Was a little concerned because the price was so attractive. Ordered, they shipped promptly and I'm very satisfied with this piece. The NB carrier makes cleaning the bolt group so much easier, plus, it makes my rifles stand out.
