matrix arms?

I have a few of their handguards as well. They're decent for the cost, but need some relief work around the gas block to prevent contact. I do like that the barrel nut does not have to be timed. They are a lower cost product though, despite what their website claims for MSRP. (Most of their handguards are available for $40-$50.) I haven't seen one of their complete rifles, but would expect similar build quality - better than some, but maybe in need of a few tweaks for best performance.
