My new BCM middie has a triangular front cap to hold the hand guards.  I just called Cav Arms to buy hand guards and they say theirs is round in the front, but can be used with triangular cap on front of BCM middie.

Sounds sub-optimal to me.  Does anybody make hand guards with triangular piece to fit end cap tight?

I asked a similar question a while back. From what I understand, any mid-length handguard will work with a mid-length upper. Also, I think it is typical for a mid-length upper to have a triangular endcap. I'm sure that those more knowledgeable on the subject will be along shortly.

Right, the Cav Arms C8 hand guards work with round or tri. caps. Not many HGs are triangular.  The C8 work an look great.

The handguards have a round end to fit in a round cap but also have cut outs so that the triangle cap fits in perfectly. My handguards fit fine.


PS I think this is the way the rifle length handguards are made too but I do not own any so I do not know.

I picked up a set of these at a gun show and they work fine...  the rounded part fits in the center of the triangle and there are "tabs" that sandwich the front cap between the rounded part and the tab.  I hope that makes sense.  They fit just as tight as the factory Stag carbine handguard, but I can not attest to their durability.  Durability in the sense that the heat shields remain attached to the handguard.  $20.  Sorry no pics of my setup, but it works.  I would call and ask to make sure the current M&A offering mimics what I have.  I was under the impression they were Cav Arms, but I have no idea.  They were purchased loose.

Most mid length hand guards do fit the triangular end cap. There are some mid length four rail hand guards that don't.

The YHM four rail one's don't fit the triangular middy end cap. ask me how I know
