Up for sale is my ARMS SIR AR 10 rail system. It has been mounted on my AR 10 since new and have fired around 300 out of it with this rail installed, Rail is in Excellet condition, no scratches, gouges, stipped screws/nuts. Light scope ring marks. I'm going another route with my handguard, don't need all the rail space. This is an awsome aggresive look for your AR 10, comes complete ready to install. Any questions please ask. Asking 300.00 SPF on ARFCOMShipped.

UPDATE I spoke to tech support at A.R.M.S this morning, model number for this S.I.R system is #53. It will work on SR25 rifles if you change the barrel nut, It will not work on DPMS or others, Only AR-10 or SR25. This model was discontinued 3 years ago, I haven't been able to search or find any info by searching the model number. A.R.M.S makes an identicle rail for the M-15 model #59M.

**this is not my Rifle, I borrowed this pic from Arfcom, This is an AR10 with the SIR rail.**
