Questions & Answers
What is the difference between the 4' and 6' rail systems? Expert Answer

If you're referring to the 4.9 and 6.5, it''s the length of the accessory rail, and the number of slots - click on the photos and you should be able to see the difference - 6 slots vs 10 slots.

Please help me under stand the difference between the KDG MRX5-110 and the MRX5-120 Which have M-Lok at the 3-6-9 positions ect... Expert Answer

The difference is that the MRX5-110 uses a "industry standard" modular system whereas the MRX5-120 uses the Magpul M-Lok attachment system. If you are looking for the M-Lok rail is it MRX5-120.

Easy upgrade to SCAR foregrip by Triton, December 28, 2016
Let's face it, the factory foregrip for the SCAR leaves much to be desired. While the price for the KDG MREX seems a bit high, it turned out to be well worth it. The MREX significantly improves the feel of the SCAR while adding plenty of Mlok slots...

Gunsmith installation necessary by john, Verified Owner, November 25, 2017
this is my 2nd installation of this rail on a SCAR and both times it required the receiver be slightly drilled out to not strip the screws. Once installed a great product but i don't recommend modifying your receiver to install it.

Awesome rail by Scar owner, April 13, 2019
As advertised, it only adds 3.6oz (that’s the longer rail too) to the guns weight. Construction looks very solid and well made. Comes with everything needed to install (torx wrenches, vibratite). Highly recommended.
