Hi Ben, the LWRCI 8 hole rail sections do not appear to be available anywhere, even from LWRCI.
The website in the 2 answers below (lwrcfirearmsusa) ia a S C A M website. DO NOT order from there, you will lose your money. They only take Zelle, bitcoin, and Apple Pay. Once you use one of these methods, you money is gone. You can even order a gun from them without a FFL. It is not a legitimate site.
The genuine LWRCI site is here >>> lwrci.com/ , and even they do not have the 8 hole rail.
Stay safe & have a great day!

Benjamin Sir,
According to LWRC International's website, there is no separate 8-hole rail section for sale. The modular rail system uses sections with a different number of holes that can be combined, or you can purchase specific 4-hole rail panels that can be divided. Your best option is to buy the LWRCI Rail Section Kit 4-Hole and use two sections per accessory mounting.
Sorry Benjamin I couldn't be much help.

The 8-hole LWRC rail sections may be difficult to fulfill, as the company primarily sells shorter 2, 3, or 4-hole sections for their proprietary modular rails. The best option is to purchase several of the available shorter sections to achieve the length you need.
Here are some places to find LWRC rail sections:
Official LWRC store
The official LWRC website is your most reliable resource for new, in-stock rail sections and other accessories.
What they offer: They typically stock 2-hole, 3-hole, and 4-hole kits. If you need a longer 8-hole section, you can combine two 4-hole kits to get the required length.
Availability: Stock fluctuates, so check the site regularly for availability.
Online retailers
Several major online gun accessory retailers carry a range of LWRC parts, including proprietary rail sections.
OpticsPlanet: This site has carried LWRC Picatinny rail sections in the past, and you can sort by brand to see their current selection.
MidwayUSA: A large retailer that stocks parts and accessories for many brands, including LWRC. Their inventory changes, so search for "LWRC rail sections".
