When I got them I was happy with the fit and finish. They seemed solid and were just what I needed. I went to install them with the intent of using them with a drop in handguard. Installed with the handguard cap, the gas port on the block would not line up properly with the gas port in the barrel. I tried them without the handguard cap and still not a good alignment. I compared them to a few other gas blocks I had in my parts box and the gas ports in these blocks were further in from the edge about 1/8″. I’m not sure if I got a bad batch or if this is how they come but I can’t use them.
I’d return them but at $15 each I’d lose a big chunk of my refund in shipping costs.
If your build allows for the extra 1/8″ or so from the edge of the block to the gas port then buy them. Otherwise avoid this product.

I didn’t receive the same one as pictured veriforce sent me a different one which was actually the one I was wanting, the top has 4 picatinny slots and no bottom rail. Worked perfectly on my dissipator build because my front sight is a perfect fit for the 4 slot rail
