Good cheap target shooting sight

by Westley, Verified Owner from CA, United States Written on June 7, 2013
The description must be changed to add that this is for a RAILED GAS BLOCK. Will not zero if put on the same level with the rear sight. IF you install this on a freefloat tube with rails you will not be able to zero. Again, this must install on a railed gas block gun like a stag model 3. This is all metal so should work just fine for that.
Pros: Cheap, works
Cons: feels a little cheap (duh) dont trust your life with it
Would recommend: Yes

AR-10 Iron Sights

by Legacy Reviewer, from WA, United States Written on February 15, 2013
My AR-10 didn't come with iron sights. I like the sights because they mount so easy on picatinny rails and they look good.
Pros: Easy on Easy off.
Cons: Not for long shots
Would recommend: Yes
