Mlock Picatinny Rails. 3-3-5-5-7-7 Slots 6 Pack Aluminum Single Picatinny Rails Section for Mloc System with 13 T-Nuts & 13 Screws & 3 Allen Wrench

Easy install. Looks and fits great. Very sturdy and light weight.

These are way better quality than expected, and a massive savings in comparison. Use needle nose pliers to hold the t-nut in place. Make sure to put a few drops of thread lock on your threads, let dry an hour before installing.

Easily converted the Keymod to Picatinny enabling me to attach a Surefire light my son gifted me. Nice price for the set! Seems sturdy.

These were of surprisingly good quality for the price. For the price paid, one would expect cheap plastic. They seem to be to spec, quite sturdy and have decent coating. I’m pretty hard on my gear as it does actually go into the field, so time will tell. I have used three of them and they all mounted without issue on an Sig upper. Only small gripe was no locktite on the screws, but for the price I understand.

Great accessory for the price. Varieyt pack covers all your needs.
