Basic AR-15: DIY Low Profile Gas Block and BCM Rail Upgrade

Upgrading your AR-15 rifle is a given for most owners of these guns.  Custom DIY upgrades are possible.

In this video we continue our AR-15 Upgrade series with a DIY low profile gas block and the installation of a quality free float rail from BCM. Free floating the barrel allows for the most accuracy potential since nothing can interfere with the frequency of the barrel as with the standard handguard setup for example. Stay tuned as we will be doing more accuracy testing to see what improvement can be seen from our previous tests as well as another range session out to 600 yards using match ammunition.
