Good product with one drawback - TAC Two Piece M-LOK Handguard

I bought this rail to replace the spongy plastic handguard that came on an old carry handle/ A-frame AR. For that, it works great and gives you mounting options. Plus, with the two-piece design, you don’t need to remove the front sight post.

Using a 7/8in riser on a red dot allows a perfect co-witness with the sights.

However, there are some flaws in the system. My Delta-ring has a small bit of twisting movement to it. This transfers to the hand guard causing an irritating twisting movement. Also, mine isn’t a perfect fit in the round style end-cap causing movement there as well, which really throws off the red dot. This really isn’t a fault of the product, just something that you might encounter.
