Works fine, pretty basic

Pretty basic. Not happy with price overall, but I haven't had a problem with it. This is about as basic as they come, but function is fine.

Great budget handguard

Great budget ar15 handguard. Came with the barrel nut and screws, just need the appropriate wrench size as it does not come with a wrench tool. Rail has held up for me for 4 months since this post. The only bad thing I can say is I wished that it had the foxtrot mike logo on it since it's such a nice logo.

Great product

This is a great light weight handguard and it is stiff enough to hold other accessories.

Very light in weight i was surprised how light this was especially considering how inexpensive it was. Fit and looks are as nice as more expensive ones. Would definitely buy again for future builds
