I am looking into getting a bolt conversion kit for simunition for a couple of ARs and was asked if my AR has a sporter block. What is a sporter block and how do I know if I have one? Thanks |

First, do you have a Colt? While I'm no authority on Colts, I'd assume the question refers to a "sear block" which IIRC is only found on Colt Sporters. At one time Colt was pinning a block into the lower receiver to disallow the addition of a drop in auto sear (DIAS) or a Lightning Link (LL). This can be seen by a spare pin in the lower receiver above the safety selector. (And at first glance appears to be a FA sear pin until one realizes it's over-sized) IIRC, they did away w/ the pinned in block and just have the lower receiver shelf built up, which prevents the use of either a LL or DIAS. HTH. Sly |
