I’ve only gone out to the range with these rails about 4 times so they don’t have scratches. These rails are used with your m4 profile front end. I have the bushmaster patrolman rifle and it was put on those. I’m willing to get rid of them for 120$ I payed 200$ for them they will be shipped Priority mail which takes roughly 3 days. I’m very professional about selling so I take all emails and transactions seriously. I will accept money order and I use paypal(additional cost) but I charge a little more when you use it since paypal takes a bit of the money. As soon as I receive the money it is shipped in less that 24 hours and thats a promise. Thank god for the 24/7 priority mail box

No tools required just your hands and some strength to pull the delta ring back.
