Product Overview

Now shipping with our new custom Torx T20 fasteners!

Anchor® - A bi-directional vertical foregrip for M-LOK rail systems, with a 1 MLOK slot footprint, allowing it to fit inside the cutout of our XOS-H Scales. Our Anchor foregrip is reversible, which allows for either a 90º or a more relaxed 70º angle. The Anchor forend grip features the same Honeycomb texture as our patented RailScales for a maximum non-slip grip. Our advanced design and machining make it lighter than nearly all other polymer vertical forward grips — no more sacrificing material strength for weight. Each Anchor foregrip has 236 machined faces and takes 46 minutes to individually machine on a 5th-axis CNC.

    Posted by Robert Nieto on Nov 22nd 2023

    Did some research and looked at some suggestions from YouTuber I trust. Narrowed it down to a few but this one caught my eye with its appearance and recommendation. Waited a few months for it to become available for my keymod on my Sig Mcx. After ins Love the product. Keep up the great work

    Anchor Vertical

    Posted by Jimmie Meadows Jr on Nov 16th 2023

    Have been waiting a long time to finally decide to make the purchase. Sent an email to receive notification of restock and purchased as soon as it became available, well worth the wait, very high quality. It’s a premium part with a premium price but for a special build it well worth it.

    Railscales Anchor

    Posted by Matt Martin on Mar 13th 2023

    Full disclosure - The 2 of these that I purchased were blems but if there's an imperfection on either of them I can't find it. I'm stoked to finally get my hands on some not to mention this was my first experience buying directly from RailScales and the service start to finish was awesome. My order was in my mailbox in 2 days and the fact that it came with a couple free stickers and thank you notes really sold it for me. This is obviously a company that not only has impeccable standards but truly cares about the customer experience.

    Solid base

    Posted by Josh on Feb 27th 2023

    This is built like a tank. The vertical surface is a great barricade stop. The other side is very comfortable driving the rifle into your shoulder. Lightweight and has a ton of grip. This could eat up your hand over time. Feels perfect with gloves.

    This thing goes hard. Will say I wish the fasteners were of higher quality. Found to be really soft. Had to get torx bolts from store after I stripped one at 15 inch pounds.

    Anchor vertical grip

    Posted by Justin on Jun 11th 2022

    After using several different types of vertical grips from several major brands, I had given up hope that I’d find one that I actually liked. A buddy let me try his anchor out on his rifle and I was immediately won over. I ordered one at the range and eagerly waited for it to come in. As soon at it arrived I placed it on my rifle, carefully selecting the best location. After a day of dry fires with it, I took it to the range and shot better than I normally shoot. My recoil management was better, my time to get sights on target was fast and I had more control on multiple target strings. After the range I wondered why it took me so long to find this gem, but thankful I did. This is a solid product and I’m ordering a second for my other rifle.
