I'm looking for an upper for my njgunforum.com ar 15 lower once it come in I don't want a 5.56 as I have an ar in that caliber I would like a 5.7 like the p90 but ammo is hard to find I want an upper where ammo is easy to find I do not know how to reload am not allowed to reload where I live so no suggestion a caliber that is easier to reload then buy new. Also please no 22lr uppers either

 

I have handguns in

9am

45acp

38spcl

And 357 mag

 

An upper in those would be cool but would like to skip getting a 9am as I have a kel tec sub 2000

Not going to find an upper in 38/357. 45 requires a different magwell than a 223/556. What about 300. Can use the same mags as 223/556.

300 how easy is ammo to get and price point of ammo and will p mags work with 300

5.45x39

300 blackout are available again. 300 blackout uses everything same as 556 except for the barrel. Excellent caliber. Same as 308 winchester. I love mine.

That's good so I don't have to get diffrent mags any uppers in 300 blackout recommendations

 

 

And of farmer

Do I have to get diffrent magazines then what I use in my 5.56 ar to use 5.45x39 and is the primer corrosive like the 7.62x54r

I wonder why no one made a 38/357 upper is it because they are revolver rounds

How about 6.8 spc?

No clue but would like to know since I was  also thinking of another upper, I am watching this thread

Do they still make a 7.62x39 upper? That would get you into a 30 cal round cheap. 300 blackout is running about $1/round.

5.45x39

Ive been wanting to do an upper in that caliber since ammo is dirt cheap, but where the hell do you find them?

Boom!

5.45x39

bingo was his nameoh ...

Russian 5.45X39 will probably be corrosive. Because it is a necked down x39, magazines could be an issue too, as the taper of the shell requires a tapered mag.  Have heard Magpul E-mags have worked but we are not allowed 30 rounders.  P-Mags have be hand modified, but again not in blocked mags.  So finding mags could be an issue.

 

38/357 does not work well in semi-auto platforms, as the case has a rim at the base for head spacing.  Most common AR rounds headspace on shoulder or case mouth, much easier to do.

 

300BLK is a shortened 223/5.56 case to accept certain 30 caliber heads.  This allows same bolt and magazines to be used, just a barrel change.

 

There are about seven or eight different calibers available for use in an AR platform.  Outside of 223/5.56 or 7.62x39 most are not priced to compete with these standard market rounds.  Pistol caliber AR's all have their own individual issues from magazines to bolts, etc.  DDLES does make special AR lowers to run 9MM or 45ACP with Glock magazines.

This list is in no way complete

I built one chambered in 7.62x39 and ive seen them for sale around. Bottom line when putting that caliber in an AR is finding a mag that feeds reliably. other than that its wicked fun to shoot and cheaper than most calibers.

 

I am currently building one chambered in 9mm

The 300 blackout might be the way to go unless 5.7 x?? That the p90 uses ammo becomes easier to get I wish I could find a 410 guage ar upper but heard they had problem

that is an awesome price but i would check the lead time with Model 1, then see if anyone on the forums can attest to their function, fit, and finish

What's lead time?

What's lead time?

Lead time is how Long before something is available

I the 5.45 looked perfect as ammo is not expensive but from doing research looks like a regular ar mag won't work the mags needs a little modification to the follower and in jersey that's not possible and I only found 30 round specifically for the 5.45

I played around with someone's 7.62x39 AR and it was an absolute blast and just as accurate as 5.56. For a 'different' AR with readily available ammo, that's my choice.

DITTO, well said.....cheap ammo thats not corrosive and mags that are readily available. barrels and BCG's in that caliber can be found at many stores online. 

 

ARDepot.com is one i know of. I got my whole BCG from them and they automatically install a longer firing pin to get through the Russian primers....that firing pin and a stronger hammer spring from Wolf Springs (www.gunsprings.com) and it goes bang every damn time. Stronger extractor spring will help FTE issues with that particular cartridge. From there, a decent mag and your GTG.

Not a bad pig hunting gun either.

Holy crap that sounds like a good time and a huge supply of bacon. What state do I have to go to for this?
