[b]Both sold pending funds.[/b]
Gas block fits .750" dia barrel. Great when you don't want the front sight interfering with the picture in your optics. Both are Armalite, I think.
Retail for gas block is $42; I will take $30.
Retail for front sight is $50; I will take $35.
Get both for $60.
Buyer pays actual shipping and, if applicable, 3% paypal fee.
Thanks for looking!
