Picatinny Weights for Training?

I have an older S&W M&P 15-22 with the pic rail. I am looking to make it heavier for training purposes. I can put some weights in the grip and possibly the buffer tube. What I'm looking for is something to put out on towards the end of the pic rail to make it nose heavy as well. I dont want all the weight on the back end.

I found the American Defense, but $150 is more than i want to spend on something like this.

I'm not looking to fine tune a competition gun. I have a private 200 yard range with steel targets/barriers at various ranges. I am looking at incorporating stress and a little cardio by running bounding drills. I have identified a weak point in in my training, and it is my physical fitness and only shooting from my bench.

I am also open to other ideas to accomplish this goal.

Thanks

What do you mean, "for training purposes"? What are you trying to accomplish? The reason I ask is because the distribution of the weights may end up with unintended consequences. For example, you put weights on the picatinny rail near the muzzle and maybe now you don't have a holster that will hold the gun and you have dramatically tamed recoil and therefore improved your shooting artificially. It will also reduce felt recoil, quite a bit.

You might be better directed to do series of regular workouts using dumbbells. Or, if you are just going for improving arm strength while handling pistols, wear wrist weights. and not gun weights.

I want my plastic .22lr AR to mimic one of my actual ARs.
 
Buy a heavy bipod and mount underneath. Extend the legs as needed to help with balance. Put a sandbag in the buttstock. If you can't get in the buttstock, add weights to a stock saddlebag.
 
Alright then..

One trick competition shooters employ is using hollowed out WML's filled with lead.
 
The cheapest way to add weight to these is to find flat barstock lead or brass/bronze to slide down inside the handguards, bolted through the handguard from outside, in.

There are a few picatinny weights out there, but most suck, and most are very expensive. Be mindful also, adding a lot of weight (as is needed) to plastic components may cause increased likelihood of failure and increased fatigue rate.
