I have a M&P 15-22.  I modified the upper and did an M4-style conversion.  I wanted to have a stock upper as well so I could switch between the two.  I bought an upper receiver and barrel from S&W.  They would not sell me the barrel extender or the ejector.  They referred me to Mel Chung on Molokai.  I called him and he basically told me that he cannot help me.

Does anyone know of a local shop/gunsmith that can get the barrel extender and ejector?  Also possibly install it for me?  Thanks for any help.

I know dex at xring worked on some 15/22 try him

Thanks.  I sent him a PM last night.  Waiting for his reply.

If they won't sell the parts we may have to make them.

Thanks for responding.  So either you could try to get the parts from S&W or you would need to make them yourself, but either way it could be done?

Ballpark how much would it cost if you needed to make it yourself?  I wouldn't mind having to wait because the barrel is kind of useless to me as-is.

I think I would be able to make it to your shop on Wednesday before you guys close and drop off the barrel.

Thanks again.

Just curious as to why you want a 2nd upper
With the time,money and effort you're gonna be putting into it you might as well buy a whole new one

We close at 5. I should be there by 2.

Bring the other upper also.

it wasn't supposed to be expensive.  A new barrel and upper receiver only costed me something like $110 shipped.  I have my stock barrel nut and stock handguard.  S&W gave me the impression that Mel Chung was going to be able to supply the few parts I was still missing.    I am still hopeful that in the end it will be worth it going this route. 

I didn't really want to have 2 full 15-22's.  I was going to stick a scope and a barrel shroud on this new upper and keep the red dot and magnifier on my converted upper.  Then I could just swap out the upper to whichever one the wife and I felt like using.  If I got another .22 rifle I think would want a 10/22 before another 15-22.

Thanks!!!  I work half day and have a doctor's appointment at 1:30 in Kalihi, but I don't think it will be a problem getting to your shop in time.
