Chart of PCP guns by weight?

I have not seen such a chart.

If a bullpup is a possibility then the P15 comes in under 4.6 lbs. I think just above four pounds. There is a new model with forward cocking but I don't recall the model number.

The Marauder Pistol in carbine form is probably the lightest but the factory stock is much too long for most kids.

I started my boys on a Marauder pistol (aka P-rod) and regret not getting a stock adapter and adjustable stock right away. I wanted it to fold for my personal backpack use and was waiting for a supposed new shorter adapter to leave sufficient room for a folding mechanism and still have a short enough LOP for my youngest son. In that time I picked up a used Leshiy Classic that was even better, albeit slightly heavier.

At any rate, if weight is the primary concern then a P-rod with an adjustable stock would by my first choice, especially if your daughter isn't done growing.

I did end up preferring the Classic Leshiy simply because there was no doubt if things were safe just by glancing over and seeing it folded open. I think with only one kid to keep track of that wouldn't be as much of a concern but it was good peace of mind for me. But it is slightly heavier and a more expensive option.

The Benjamin Marauder pistol is a very light gun as well. I have put together several similar guns and they are under 5lbs.

The Fortitude is a full sized gun but a featherweight also.

Vixen short is 4.4lbs I think the long is 4.8 ish. 

The Buck Rail stock adapter for the Prod is shorter than the RAI adapter. The Benjamin Maximus is also a slightly over 5 lb gun. The Maximus/Fortitude stock is basically hollow but could be shortened if necessary. 

While I own many pcp’s from bench rifles to carbines I have to give you an ‘A’ for already answering your own question. The gen2 Diana Stormrider is the perfect offhand rifle for a youth or adult. Like all the others it falls short in some categories but otherwise is the perfect American sporting rifle platform.

I’ll be a smartass and mention the AEA Element because I love mine, but I highly doubt that would suite your purposes. I was thinking similar to Marquette in a Diana Bandit with a Buck Rail setup. If she doesn’t take to it you are out peanuts. If she does, plenty to learn wrenching on that gun. Bottle it, Stormrider barrel, ect…

Stoeger XM1. Ck it out. I love mine in Camo with super nice suppressor and optional bi pod. Similar but better than Stormrider.

If I remember correctly the was a guy on here who made a list of Bullpups and rifles by weight and length but I don't remember who it was.

jungleshooter put this one together a couple years ago. He did an excellent job with it.

I remember one within the last couple months, but don’t remember if it was on here or GTA.
