Client-side validations can be useful, but are generally unreliable if usedĪlone.In heavily-used tables) that can be difficult to implement otherwise. Additionally,ĭatabase-level validations can safely handle some things (such as uniqueness Idea to use some constraints at the database level. However, if your database is used by other applications, it may be a good Database constraints and/or stored procedures make the validation mechanismsĭatabase-dependent and can make testing and maintenance more difficult.There are several other ways to validate data before it is saved into yourĭatabase, including native database constraints, client-side validations andĬontroller-level validations. Needs, and allows you to create your own validation methods as well. Rails provides built-in helpers for common They are database agnostic, cannot be bypassed by end users, and areĬonvenient to test and maintain. Validations are the best way to ensure that only valid data is saved into yourĭatabase. For example, it may be important to your application to ensure thatĮvery user provides a valid email address and mailing address.

It ultimately comes down to what you’re looking for out of your build. Many shooters have used them for years without any issues and some even prefer them to free floats. While traditional handguards may not always be as accurate as their free floating counterparts, they are still a viable option. This allows you to not only use any accessories you prefer but also lets you prop your rifle up to aim against any surface available without the fear of accuracy loss. They have even been known to increase your accuracy in the range of. This in turn slightly changes the angle of the barrel, making your shots less accurate.įree float handguards, on the other hand, don’t have this issue due to their floating nature. The force created pushes against the handguard which ultimately pushes back up against the barrel. The problem stems from when you prop your rifle up against a surface to aim, use a bi-pod, grip, etc. Unfortunately, traditional non-free float handguards are sometimes prone to this issue of barrel warping. This bending, also known as warping, is the culprit that causes your accuracy to suffer. The less chance there is for the handguard to make contact with the barrel, the less chance there is for the angle of your barrel to be slightly altered. Preventing your handguard from touching the barrel is key when you want to be as accurate as possible. (Example of how a free float handguard never makes contact with the barrel)
