western mass.
I live in mass. and the 6 position collapsible stock is fully extended and pinned. I just took my wife to the range and she wanted to shoot my mp15....she liked shooting it and had a good time but she is a small woman with short arms and she needs a collapsible stock. I hope their is a way to make it collapsible again without having to buy a brand new stock.....i know im going against the rules in mass. but i want to give my wife an enjoyable time at the range. Please help

You could conceivably unpin it and move it to a compromise position and repin it, OR get her a Sport:D LOL
 
I would find out what the penalty is for having a non-compliant firearm in my state. (I think it is something like a 1-10yr sentence or $1k-$10k fine.) You can do anything you want IF you are willing to accept the consequences. IMO, buying a new rifle and having it fixed to fit her is the easier, softer way, but that's just me.
 
You could probably adjust it to a shorter length and re-pin it. That way it's not adjustable, but fits a smaller shooter. You could then use a slip-on recoil pad, like a Pachmeyer, to give you a proper fit. In principal, that's no different than what you'd do with a wooden stock.

Stocks are very easy to change on an AR. If you don't want to be seen with a sissy-pad, buy a second stock, pinned of course.

That said, I'd need a compelling reason to visit Massachusettes, much less live there rather than a free state. It's bad enough to be trapped in Illinois.
 
If you unpin our stock and leave it collapsible and get caught and convicted, you will probably also be saying good bye to any hand gun permit you may have.
I would stay legal and take another route to have a rifle more comfortable for her to shoot.
 
I am not sure about the M&P, but most compliant stocks are not adjustable. They are made to look like a pinned adjustable stock but are actually not.
 
So you buy an adjustable stock and then put either screws or a bolt in it so that you have to use tools to move it. As I understand the way the law reads, an adjustable stock is one where as you can adjust it without the use of any tools. If you drill and tap the bottom of the stock to where you can put an allen headed set screw in it, a long one. You could lock the buttstock down, then pull out your allen wrench loosen off the set screw and slide it to where you want and then tighten it back up and still be within the letter of the law. I would do it from the bottom because that is where the locking bar is for the adjustable stock and you could have your allen set screw, still thinking like a 1" long one, lock into the pockets that the regular adjustable stock locks into, without messing up the buffer tube. you could also do it from the side but I would put an allen on both sides to keep from cocking the buttstock and it would look more locked and non adjustable. With an allen wrench it wouldnt take long to accomplish the change about a minute but once the screw is put back into place you dont have an adjustable stock. That is how target rifles with completely adjustable stocks get away with it.

If anyone does this and patents it, I only want 1% in royalties. LOL

I agree with oneyeopn that is the best way and stay legal, in NC if you are convicted of a felony you can't even touch a firearm so I wouldnt take a chance.
 
The compliant stock is not adjustable. You need to remove it and replace the buffer tube with an adjustable buffer tube and then install and adjustable stock and then PIN IT!

Technically, you must leave MA to do the install. Go to a friends in NH, have a stock shipped there and swap it out up there. When you come back to MA it must be pinned.

Possession of a collapsing stock if you own an AR can get you charged with sonething along the lines of "attempting to build an assault rifle"

This state blows. Why I had to do this.

Mustang5L5, If he does as I suggested will he still be breaking the law? I havent read his particular state but have discussed this with some people in other states that have to deal with this situation and the use of a tool to adjust it makes it legal. Just wondering. Thank you sir.

You bring up sonething that has been asked with no clear cut answer. Your idea is valid, but no official word on if it is legal here in MA. I've wondered myself and it's frequently discusses on the local forums.

The general accepted practice is a blind roll pin. That's how the factory pins the stock and it's accepted and recommended by law enforcement.

Guys have installed magpul moe and Ctr stocks and replaced the adjusting mechanism with solid pins and then pinned those in place. Is it legal? Who knows? Can't get official word.

Most agree that if you keep your nose clean, nobody will ever look at your rifle anyway. I'm not advocating breaking the law, but nobody has ever asked me if my 30-round mags are Pre ban or not...and I frequently share the range with LEOs.

I went with an A1 stock because I liked the look really.

California compliant Sports are equipped with the adjustable stock, fixed magazine (bullet button), and limited to 10 rds. I believe the one I'm picking up this Saturday has a flash hider also.

If your state has regulations as to what constitutes a "legal" weapon, I would not alter it in any way that could land you in trouble. If you're at the range and LE discovers you've altered your weapon you stand the chance of being arrested, fined, jail time, having your weapon confiscated, and if you have a CCW it will be revoked. Better to do what others are saying and buy another weapon.
 
The idea of a pinned stock in the compliant states are to have the gun fully extended so you can't sneak it in to the movies under your coat. They really don't want us to have any fun! I won't change the stock on any of my guns as I still want to own them and stay out of jail.

There is a minimum length that the rifle needs to meet. 30.5" If the stock is pinned, and meets the minimum length, you are GTG.

If there is a concern of working on the rifle- is it legal to change it, could you get in trouble, etc. then do THIS: Disconnect the upper from the lower. It's now PARTS and not a complete rifle. Work on the parts, and once each piece meets the requirements for a rifle, assemble and go shooting.
