Excellent for my application - Stern Defense SD MOD4 M-Lok Handguards

I found out about this brand because the 9mm AR I bought last year had a 4 inch Stern Handguard. I replaced the 5 inch barrel with an 11 inch barrel and wanted a 10 inch handguard. Since I found nothing wrong with the existing Stern 4 inch handguard I purchased the 11 inch one. Keep in mind you will need to buy the wrench from Stern's website (which I didn't mind doing). I read some people had trouble with gas tubes but my application on a 9mm AR is blowback so this worked great for me. It is of high quality and not ridiculously expensive. I see other handguards made of the same material for double and triple the price. This works fine for me.
