BCM blem uppers $49

[teratos]

All the blem uppers I’ve bought from BCM had no significant blems. Great uppers. Just remember they are thermal fit!!!

I just went to post this same sale. I have bought quite a few of these "blem" uppers and have never been disappointed.

Lol. Yes! I put this in the original post.

Yup. It says somewhere in the ad that heating them with a hair dryer or heat gun is required.

Just wanted to make sure they were the original item.

You can do it with a torch in a pinch. I use a heat gun.

Very difficult to lap.

I thought you weren't supposed to lap those.

I thought you weren't supposed to lap those.

You aren’t….because they are too tight. I have a lapping jig somewhere that fits them, though. Lol.

Though I don’t usually lap them. No need.

I know this post is about the unassembled uppers, but I bought a complete blem upper in this sale. Its coming Thursday. If anyone would find it useful or helpful I can post pics here once it comes.

Good. I keep buying parts on sale like this, then end up having to buy more stuff to build uppers I don't actually need...
