Excellent quality - Magpul Industries MBUS Pro Offset Deployable Iron Sight

I installed these sights on a 20 inch 556 varmint build for close up shots when the scope is not practical to use. Magpul pro sights are just awesome! They are very solid and are not plastic. FYI it you plan to use these offsets on a free float handguard then I recommend you use a very high quality handguard ie. (BCM or Aero). If your handguard has much flex in relation to the barrel then offsets will not work well.
