An upgrade to any weapon should be something that either looks good or improves functionality. In a perfect world, the change will do both. Many shooters jump into the upgrade culture a little at a time. A great starting point that hits both marks is an aluminum Ambi endplate.


If weight isn’t a factor in your world, go with a steel endplate and be done with it. However, if you’re looking for places to save weight, a Ambi End Plate is it. I know it’s not much, but when you follow through with other lightweight components, it does make a difference. Velocity uses strong, lightweight 6061 T6 aluminum as a source for its Ambi endplate. The quick detach point is an added plus in case you ever want to add a sling.
