BlueLineFish 615 Posted December 22, 2013 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. Quote Share this post Link to post Share on other sites

DL75 0 Posted December 22, 2013 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. Quote Share this post Link to post Share on other sites
blizzzarddemon 0 Posted December 22, 2013 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 Sent from my SM-N900V using Tapatalk Quote Share this post Link to post Share on other sites

carl_g 568 Posted December 22, 2013 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. Quote Share this post Link to post Share on other sites

T Bill 649 Posted December 23, 2013 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.

NYMetsFan86 9 Posted December 23, 2013 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 Quote Share this post Link to post Share on other sites
blizzzarddemon 0 Posted December 23, 2013 The 300 blackout might be the way to go unless 5.7 x??

blizzzarddemon 0 Posted December 23, 2013 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 Sent from my SM-N900V using Tapatalk Quote Share this post Link to post Share on other sites
Jon 264 Posted December 23, 2013 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. Quote Share this post Link to post Share on other sites

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. Quote Share this post Link to post Share on other sites
