Is this too much gas block for a AR10 .308 win ? — 1 Answer

This is not too much gas block for an AR-10 however there are design flaws that may render it unusable for your application. According to JP Enterprises you will need to purchase a tap, remove all screws then re-tap the gas screw hole with the gas tube inserted. This process may or may not work to make the gas block perform properly depending upon the tolerances your new gas block was machined to. The quality control on this block is poor and JP will not stand behind this product. Just remember- BEFORE YOU PURCHASE- that this gas block will not work under any circumstances on any application without first modifying it with the use of a tap that you must purchase additionally according to JP Enterprises.
