Satisfactory - AT3 Tactical SPEAR M-LOK AR-15 Free Float Handguard

I actually have bought 3 of these rails over time. They fit seamlessly with the AT3 slick side upper and give the appearance of a monolithic upper.
They work great on mil-spec uppers as well and they look good on them.
These days i only buy rails with anti-rotation tabs, just seems like common sense these days.
I appreciate that it comes with a barrel nut wrench with a 1/2" square for a torgue wrench.
The lock up is solid especially with the additional set screws. My first installation the rail did begin to back away from the receiver, i had noticed a small gap had developed. the installation instruction said to tighten the set screws until they bottomed out on the barrel. I reinstall the rail using 5lbs higher torque on the clamp screws, and then actually tightened (hand tight but still tight) the set screws, using loctite on everything. Have not had issues since.

The finish on the fde is pretty close to Being spot on with magpul furniture.

The black finish however, i am not happy with. When the sun is shining on it, it has a slight purple hue which is extremely noticeable when wearing sunglasses, though it is not noticeable under normal lighting conditions to the bare eye, simply looks like a matte black. Not a deal breaker but worth mentioning. This is why a star is removed.

Id like to see an integrated QD socket but i understand some designs intentionally leave that out, obviously an mlok attachment can easily be added.

Overall a great rail for the price range
