    PRI Gas Block With Top Picatinny Rail

    Outstanding product, perfect machining and easy to install and aligns well with the top rail of the handguard, it also comes with 1 shim if needed. I am having an issue with gas port alignment with the barrel/gas block port due to having the handguard cap on. I might have to remove the cap and buy a free float handguard. Fast Order confirmation and quick shipping. Great job BCM!!
