TuFok Picatinny Rail Section - Thin 0.27in Height Rail Attachment Rail Adapter Mount Alumimun 3-Slot Black X2

Good rails. I got the pair of 3-slot rails to not add any more weight than needed. The accessories I’ve added that needed the rails each only need a 3-slot rail. The protrusions along the bottom that fit in the M-Lok slot aren’t a tight fit like other attachments I have...they have a little slop. But once tightened down they feel solid. Others commented about the T-nuts being too large to smoothly fit through the M-Lok slots. That wasn’t the case with mine...they fit just fine. I have another rail from a different manufacturer with T-nuts that fit like that, so I’m familiar with the problem, but the T-nuts that came with these rails were just fine. I just ordered another pair of 3-slot rails for other additions.

Great quality

The machining is cut a little on the large side, so fitting was really tight compared to Magpul version. These are about 1/3 the price, and are good enough to suit my needs (mounting a front iron sight and tac light on my carbine) so the small amount of extra time spent smoothing them up was well worth it.

Really nice set of rail sections. Was looking to add a light mount to my AR15 and just needed some rails to slap on. These are aluminum so they're pretty strong and fit well on my Magpul MOE handguard. Really nice and inexpensive plus you get two rail sections which is great. Really like these and a good alternative to higher priced products.

I ordered this because I wanted a low profile pic rail. The rails I have from trusted brands like Midwest Industries are a little too thick. However, these are even thicker than the ones I have. The photo for this product shows a low profile pic rail, but that is not what I got. Plus the Alan wrench that’s included didn’t even fit the screws that came with it

This rail segment looks good and is a bit lower than the that it replaced. The included mounting hardware was not as pictured, though. You would think the screw heads should be flat with a taper under the head to match the shape of the rail they're going in. They were not; the screws had a round head that was flat on the under side and the t-nuts appear to be stainless with no coating - see photo. Bottom line is the rail is good if you have other mounting hardware available.

Perfect height for PC-9 Chassis backup sights

Nuts slightly larger than M-lok holes. I took a chance but the extra effort needed to file 4 nuts on 8 sides isn't worth the savings. This is the same of many other reviews so their quality control must have a +/- opposite of M-lok. Sorry can't recommend.
