The Strike Industries Cobra Trigger Guards are designed to be a direct replacement for the stock trigger guards on your airsoft assault rifle. They feature a deeper angle rather that gives the operator more room when wearing gloves, as well as eliminating the dreaded gap between the pistol grip and trigger guard. This package contains a classic trigger guard, as well as a right-handed guard that features a unique finger rest.

This product is amazing, these trigger guards are very well build, durable and comfortable, and they are the only ones to fit G&G metal bodies perfectly, they are the alternatives compared to the Magpul ones, and at half the price, highly recommended if you own G&G AEGs.
None, I really can't find anything bad about this trigger guards.
