Does anyone know if a Kac M5 Ras will fit a 20" upper with round handguard cap?  Thankyou for your time!

I just checked my M5, and the front end of it is shaped so that it will only fit into a triangular cap.

Most 20" uppers I know of come with the triangular cap

??Would you care to share?

Buy a tri handguard cap and knock off the FSB to install? Or do you know a easier way?

Yup. Takes all of about 5 minutes. Remove FH, drive out taper pins, remove FSB/gas tube, replace round with triangle.

Any chance  the FSB could get canted after i reinstall it?  Never done it before.

There is a chance but it usually is pretty painless. Install the pins properly. I usually keep track of which was in front and back and drive them in as deep as they were originally installed.

No. And are you sure the cap is round? Who would make rifle length hand guards that fit a round cap? Is it Magpuls?

Yes im sure the cap is round.  I have triangular on my mid length and round on both my carbine gas lengths so im familar with the cap style. 20" Upper came with standard A2 tapered handguards that fit both type caps.
