I asked this in the AA Industry Forum but got zero replies so far.






Are there any free float rail systems that will fit over the .625 Lite gas block?









I have searched the internet extensively and can't find a definitive answer to this question.






I just got a .625 Lite Piston Kit for a very good price.







I am willing to modify the rail if necessary.







I am looking to install a rail that will cover the gas block but leave the gas plug exposed for removal.







I am trying to stay away from the Samson Extended Rails if I can to increase the sight radius.

To my knowledge no off the shelf hand guard fits over the standard pencil barrel gas block.
The few people I have seen with them, they were homespun Dremel jobs.

If you have the low profile gas block, the Troy Extreme should fit over it.

Thanks for the reply. I have a few different brands of rails on some of my other ARs so I may take them off to do some testing.

 



Worse case, I will just get a Samson extended, and deal with the short sight radius, but for what I paid for the kit I can live with it.

The previous gentleman is correct, the lite block is not a low profile block. The XLP is the only low profile block that will fit under a hand guard. The lite was made to reduce weight by eliminating the top rail, but still utilizes a cutout piston type hand guard.

That's what I figured but for the price I paid I'll make something work. I have a plan for a MI 2 piece extended carbine rail.
