looking into getting a new gas block to replace the front sight tower. whats a good low profile or similiar. also wanting to put a free float tube on it. the gun just has standard handguards and a standard 16 inch barrel. the free float tube just needs to be smooth i dont need any rails or nothing like that. thanks

Brownells sells a nice upper receiver action block, its plastic and includes a no crush insert. Another option to removing the barrel is installing one of our free float tubes, it clamps to the factory barrel nut, is available in a variety of gripping surfaces, and leaves the option of mounting rails if ever needed. www.apexcncmachine.com As far as the gas block goes, even though we supply many of the low pro units to the industry, you really do have a great one hiding under that sight post.
