Reviews & Ratings for VISM M-LOK Handguard, for AR-15/M4 — 25 reviews — Page 1

Sturdy, seems to be high-quality and fits great to my AR.

This will fit on the palmetto PA-10 .308 (mid length with A2 front sight post) with modification. The rear clamping lugs that screw together do not have enough clearance to fit around the fat .308 barrel chamber. You need to file off about .10" on the left and right lugs for clearance. This still leaves enough meat on the lugs for the bolt to thread in. Front lugs needs no modification, plenty of clearance for the barrel near the sight block and the handguard fits snuggly around the triangle hanguard retaining cap. Also the little picatinny tab that goes over the delta ring needs to be filed down on the ramp section so the top handguard half can clamp flush with the bottom part of the hand guard.

Has a little wiggle side to side, if it wasn’t for that I would have given 5 stars. Lightweight, and streamlined/modern aesthetic at a reasonable price.

Good price for solid drop in handguard. Looks and feels just as solid as as my MI mlok drop in at less than half the cost

I appreciate the value as well as the material. Good looking as well.

A perfect fit on my M&P 15. Installation was a breeze. Does sit a little taller than the rail on my gas block but not a big deal. The finish is very nice. I would buy it again.

The quality seems really good especially for the price. Fits good and really improved the looks of my Sport2.

I bought this to replace my standard M-4 style handguard on a Ruger AR-556/8500, as the standard handguard has no attachment points for anything; I had sling through the fixed front site and wanted to mount a light, handstop, and better sling attachment.

This thing is GREAT. Took me all of 5 minutes to install and I'd never removed anything from this gun before.

In response those saying it moves/wiggles - I ZERO movement, not a millimeter, not a jiggle. It is rock solid.

One of the M-Lok slots I used for my light was micrometers off to fit a double length M-Lok attachment. The part fit into other slots, but not the one I wanted to use. But I just alternatively tightened the M-Lok screws until it finally wedged itself in; I'm guessing it stripped either the slot or the mount tabs as it's now flush. Worried about getting it off, but that comes some other day.

Looks like a free float rail, gives me some attachment options where I had none, easy to install, and again ZERO movement.

Fits my mid-length rifle just fine. somewhat better than what I replaced but there are some tradeoffs.
Overall it feels like a sidegrade rather than an upgrade but for the price it's not terrible.
I have somewhat lower standards so it works for me.
Installed on a SF Saint 556(replacing the B5 handgaurd)

For the "Mid-length" model
( Mid-Length Model#: VMARMLM )

Pros:
- Very easy to install, didn't even need a handgaurd install tool. Each half just slipped/pressed into place and installed the bolts, feels rock solid. Solid enough for a light but lasers might not hold zero, YMMV.
(Don't forget to apply some blue threadlocker to the bolts during install, it doesn't arrive with any applied)

- Has T-slot numbers engraved on top rail and lots of M-Lok slots all around

- Comes with 2 removable picatinny rail sections, one 5 slot and one 9 slot so I don't have to buy them separately

- Doesn't interfere with the A2 front sight post or sling mount

- Documentation states "For use with "triangle" handgaurd caps" but it worked just fine with my "Round" handgaurd cap(I think it mounted even more securely since it's so snug with the cap). But YMMV, I assume I got lucky it worked with mine.

Cons:
- Top picatinny rail doesn't perfectly mate with flat top receiver, there's a gap(about 2-3mm) between the handgaurd rail and the upper receiver rail. Also somewhat difficult keeping them perfectly level with each other when first installing, so some forceful clocking was needed to mak...

The unit I recieved was in good condition. No scratches, dents, dings, or defects. Installation was easy enough with the supplied allen wrench. However. Do not purchase this handguard with the intention of adding a laser sight. Once mounted and all screws have been tightened there is a slight amount of movement of the handguard itself. You can zero your laser, fire the rifle, and the laser will drift off zero with each shot fired.
