M-lok is on of the best - Midwest Industries G3M Series M-LOK Handguard

I have switched to only using M-LOK hand guards after having problems with attachments coming lose of completely falling apart. The M-LOK hand guards because of how well built and durable they are. I have not had any problems in the last several years since I switched. The design is well thought of and the look is very good. I even ordered a 12.5 inch upper for my 5.56 that came with a key mod and I ordered another M-LOK just to change it out because I know that once I use it, I wont have any issues.
