Hi guys - I just finished up my low-cost build.  ProFab .308 upper on an 80% lower and MOSTLY could not be happier.  I'm touching holes at 200m (which is a far as i have to shoot right now) - BUT - i hate the mounting system on this ProFab handguard.  I bought their mounting system for my bi-pod - but no matter how tight i tighten it or how much loc tight i put on - within 5 or 6 rounds, the bipod is dangling.  opinions on what to replace with?  I want it to be easy - slide the old off - slide the new on.

Ideas?  Thanks.

I used their upper and lower, I used the OdinWorks 15" mlok rail. I believe it's DPMS high profile. It mates perfectly and lined up perfectly. Lots of options for mlok bipod mounts, either sling stud or dedicated.

Do you use the long rail? They come in 2 sizes. I made rails myself from scope mount rails. The bipod one has 4 screws and 1st screw locks the rail thru the non sliding hole. Solid
