I have been building up another spare upper using a 20" AR Stoner SS barrel and a BCA side charging upper receiver. I found out that the Luth-AR Palm handguard will not clear the front of the billet BCA receiver. I did not want to admit defeat and throw the handguard under the bench so I had to grind the "wings" off the backside of the handguard. Everyone might be warned that Luth Palm handguards will not directly fit on billet receivers.
