Have Questions About this Product?
This was my first build and they worked with me to make sure I was successful and within budget. Went together great, shot accurate and no jams after 50 rounds. Will definitely come back for more ar parts.
I fired approximately 50 5.56mm rounds through this BCG and none of them jammed. It charges smoothly, and I have no complaints.
Purchased this for a premium upper build, a Nordic slick-side (no Forward Assist / no ejection port cover). The black nitride finish of this BCG is visible through the ejection port and looks as classy as the rest of the upper. Also looking forward to the lubricity properties of nitride components.
Everything I ordered and shipped very fast!
Though this is a pre-fire review, this BCG looks like it will do the trick nicely. It looks equal to my Colt Carbine BCG which was made in 1981. Work horses are not rocket science. Thank you.
