Anyone familiar with a handguard that has a large enough ID to comfortably fit over a 1.735" can? I have seen some that are 1.8" but not sure if that will be enough of a clearance once rounds start being sent downrange.
The only one I know of is the SP series from Midwest Industries but they claim the ID is 1.75".
My can is 1.6" and they have never met...but most likely far too close for your can.
You can also check out yankee hill machine. Their rails range from 1.5 - 1.8 I.D. Sometimes you will have to look at a particular model on MidwayUSA or brownells ect as their website doesn’t always list all the specs on each one. Midwest industries and seekins precision should also make what you need
