Great, but limitations - Lancer Replacement Handguard for Sig 516

As many have stated for fit and functionality, this is 5 stars. Not to mention the options for an aftermarket handrail is extremely limited. The biggest short fall is that to clean the piston you have to take the hand guard off. This doesn’t require too many screws but enough that it is very annoying. Now this becomes even more time consuming if you have a vertical grip or anything else hanging off hand guard, such as a flashlight. Lancer makes pic rail attachments.. which most people want. These attachment have to be taken off ever time to remove the hand guard.... because remember you have to clean the gun. So, 6 screws to remove the hand guard, 2-3 screws per hand guard attachment and you have to line these up.. the attachment rail mount just kind of hangs there and you must perfectly line up the holes.. it took me 45 minutes to get it all back together the other night. Again, i absolutely love the attachment, blocks the hand from getting burnt on the gas block, really durable and looks sharp, but man they failed on somehow designing this for cleaning the weapon.
