Ryan,
Can you please tell us why you think its the Rajim Matrix Jr. 48" 24lb? Are you simply eyeballing it? From all the pics I've looked at I think you're definitely right. The tricky thing is, there seems to be two versions of the RM Jr. One looks like it can definitely be the base model they selected for the screen used bow. But another version out there shows a different design where the riser meets the limbs. I'm not confusing the Jr. vs the Sr. models. I actually think there's two slightly different designed Jrs. Although the models not meant for youth probably do have the non screen accurate riser connections. I'm hoping the Rajim Matrix Jr. is in fact the screen accurate bow. I think the limbs that come with it may even be the screen accurate limbs.
