New upper, new bolt. Problems?

AR/M4 AR Technical Discussion

I apologize if this seems a bit daft and I did look, but nothing seemed to turn up that answered my question conclusively, so, here goes.

If I purchase a new Daniel Defense upper, sans BCG, should I be fine with buying a BCM BCG and installing it into the DD upper?

The only reason I ask this is because buying the upper without the BCG means that I can more readily afford my present (and rather inexpensive) build, allowing me to spread the purchase of parts out, and the upper is by far the most expensive part of my build.

Thanks!

Granted, it is always best to buy the upper and BCG, but from these two reputable companies it is a non issue.

The best thing to do is to get a headspace gage and check it. Even the best manufacturer could make a mistake. It’s cheap insurance.

If the headspace is off how do you fix it?

According to the TM, you replace the bolt first. If that doesn’t work you replace the barrel and then recheck with the original bolt.

Chances are with a good manufacturer it will be a non-issue. But, it’s always a good idea to check.

Thanks, guys, I really appreciate it!
