I love the undersized extension. You will need to apply heat to seat your barrel in the receiver. I greased the barrel extension, applied heat to the receiver with a hair dryer, and the barrel slid right in. Definitely the most secure fit of any upper receiver I have ever used. Machining and finish are both excellent and BCM applies a dry film lubricant to the interior of the receiver. I am very pleased with this one and will definitely use this receiver for future projects.

The upper was as expected and delivered faster than the projected backorder date! Thanks! I appreciate BCM uppers for their fit, finish and thermal fit properties. I do not enjoy having to shim uppers and the ability to bed a barrel using thermal fit definitely helps by build attain a higher accuracy standard. I also appreciate optics planet for their wide range of products.

I have purchased two of these uppers. One for a 5.56, 16in ar15 build, and the other for a 300blk 10.5in build. Both uppers have been top notch quality. They have both had a snug fit with the barrels (fn 16in, faxon 10.5). I had to heat both of them to get the barrels in. End result is a super accurate rifle. I would recommend any bcm product to other enthusiasts.

Honestly I'm just happy that I can be able to buy one of these (very well made) things to start building out a new upper/set up. They do what they're supposed to, arrives very clean and to spec, no blemishes, and GTG.
