okay, so i've already picked out my lower. I'm going with a mega stipped, and a chip mccormick trigger set. So now i'm working on the upper. I think i'm going to go with the Ameetec Arms - Side Charging Flattop Upper Receiver - Complete, rock river stainless 16" preban barrel, and rock river quad rail system. Now then, here's my question: The rock river stainless comes with the front sight housing, barrel extension, handguard cap and barrel nut. So I am going to need a gas tube, Barrel indexing pin, delta ring, weld spring, hand guard swap ring, and what else? what the heck is a gas block for? |

Gas block is a replacement for the front sight base. If you cut off the top half of the standard FSB, you'd get the functionality of a gas block. Some gas blocks are lower profile and some have a rail base so you can mount a QD front sight. You can order a firing pin from most manufacturers and dealers. Try any of the ABC's like Bushy or dealers like Adco. |
