B&T hand guard GAP?


Recommended Posts

Greetings all! I’ve been a long time lurker; learning and admiring everyone’s M4 build. I finally got my hands on an H2O and joined the forum. 

The issue I’m having is with the B&T hand guard. The seat ring on the barrel doesn’t sit flush against the receiver. The gap is very small, but still concerning. I’ve taken it apart several times to ensure everything is in place. 

Is this a common issue with this hand guard? Anything to be concerned about?

Hard to tell from the photo. What I would do is take it to the range a fire it. Inspect the primer hits to be sure they’re solid hits. You could swap handguards back to oem if you want a direct comparison of the primer hits. 

Per B&T, the gap is “supposed to be there”. Worth noting is that the hand guard itself doesn’t even sit flush with the receiver. I’m thinking this is just a faulty piece, as I’ve seen many M4s with this hand guard sit nice and flush. 

still need to go to the range and fire.
