Product Overview

Now shipping with our new custom Torx T20 fasteners!

Polymer RSBM-P Vertical Grip - A polymer variant of our popular RSBM vertical grip, that features grooved cuts that was originally developed for a contract end user. Weighing in a scant 1.13oz, it is the lightest polymer MLOK vertical grip on the market, a 1:1 copy of the machined aluminum version. Extra care was given to design the mold to mimic a look similar to matte anodized aluminum. Designed for PDW and shorter barrel setups, its ergonomics also find itself at home on carbines as well. The cylinder of the grip is offset 0.140" to allow for fine adjustment in its already small footprint by alternating its direction 180 degrees. When used as a broom handle style grip, the RSBM-P allows for a 3 fingered grip with the pinky over hanging the bottom. XOS-H scale compatible.

Only available in MLOK.

    Great quality foregrip just like it's metal brother, just lighter. Super comfortable with great ergonomics. You really can't go wrong with any Rail Scales product.

    Excellent fit and finish

    Super well made, only thing I wish is that they were offered jn the same sizes as the G10 version. Not sure if the polymer neccessitates them being a minimum length, but you would think that if time and thought went into determining the best lengths, especially for the use of a grip, the same logic would apply to the polyner version. On my 8.25" handguard, the 3.5 m-lok slots forces me to choose between two less than ideal positions.

    When used on a suppressed rattler in tandem with the QTR stop, the RSBM provides an extremely comfortable and stable support hand solution on this limited rail space application.

    Nice fore grip

    Posted by Armando on Sep 16th 2023

    This is a very nice fore grip option. It's a much more affordable option compared to the metal version. Although it doesn't seem like it will be quite as bomb proof, seems very solid and light weight. It's also a fraction of the price so it's a no brainer. The FDE looks dope on my PWS.

    Very Pleased!

    I'm really liking these grips. I purchased one in black and another in FDE. However, mine didn't ship with the T20 fasteners like the description states. I received the old style hex fasteners.

    Amazing products. Look Amazing everone who sees them has to know about them. I love the wrap around design. Fits perfectly on an FCD rail. Have not been able to put enough rds down range to test Heat protection.

    Great vert. Seems very comfortable. Smallish. Visually appealing. Looking forward to see how it performs
