I got these to put on my M16A2 when I went to Iraq, but we were issued M16A4s, which have a rail system so I never used these and they are still New in the Box.
I am asking $65 shipped, by paypal or postal money order. SOLD
email me at firstname.lastname@example.org
response to question: yes they will fit rifles with the triangular end cap
edited to lower price and answer question
