Whats up guys, i am shopping around for my next riffle and pretty much have decided to go with the NEA 7.5 PDW. now i am debating on getting it in 556 or 300aac. A friend of mine told me that 7.5 inch are not accurate at all in 556 and much better in 300aac. how much more accuate can it be at 50 yards? i dont plan on making such a short rifle perform at 100yards at all. if i can consistently hit a can of beer at 50yards with 556 thats fine with me.

also price of ammo isnt really a problem since i reload

cheers
 
considering a 9mm is lethal at 200 yards, i think a pdw rifle cartridge can absolutely go to 200 yards.
I think many of you dont understand the amount of energy involved here even say out of a 7.5 inch barrel.

5.56 is very rude in a 7.5" barrel

Ignore this guy (unless he's talking about something other than NEA, then he's worth listening to)...that said they have had some issues, mostly in the past. There has also been reports about Upper/Lower compatibility with other brands, so if sharing the lower with another upper is part of the plan you might want to consider another brand.

You're new here. You've missed a lot over the past few years.

The company in question produces the poorest quality firearms I have ever seen. Some people swear by them, but the number of guns that have blown apart is alarming.

My advice to you... Pick another rifle.
 
One more piece of advice... You should shoot a 7.5 AR before you buy one. I find the blast uncomfortable when shooting rifle calibers. My 7.5" AR is chambered in 9mm
 
My opinion is 7.5" PDW shooting rifle round is useless, unless there are sound suppressors to buy. The reason they make supper short PDW is to accommodate the additional length added by sound suppressor. Even 10.3" CQBR is too loud, but they issued CQBRs with KAC suppressors back in the old days when they were first introduced

If we can get sound suppressors, 300 BLK is the "caliber" with subsonic ammo. Otherwise, either 5.56 or 300 BLK, or 7.62X39 will be obnoxiously loud and ear drums splittig, if you would like to use your PDW in a "PDW" manner. Losing hearing and comm. wouldn't be a good thing in a situation where one needs to use a "PDW".

The best PDW is the B&T TP9 if no suppressors to be had - and hence B&T sold many of these to pilots and CP in Europe apparently. The US bought HK MP5 PDW for their pilots back in the late 90's, too. 9mm is the way to go IMHO for a PDW, it can be used with subsonic, AP or HP. Lots of ammo to choose from for whatever that needs to be get done.
 
This is what you've missed. Lots of hot air and rhetoric.

It's not that some people swear by them, it's a group of people who embellish every problem into an attack. To say they are the poorest quality firearm one has seen is laughable unless you've held about a 1/2 dozen. I can find plenty of rifles that have blown apart, only one NEA, due to ammo according to the report. Parts fail, things get mixed up, shillgate seems to have messed with how some see numbers...10 = 10,000...it's a strange phenomenon some weird version of scapegoating.

EDIT...I challenge anyone to find more than a tiny number of NEA's that have blown up. I do mean blown up, i.e. the receiver, or barrel in bits. Every manufacture has parts fail, or ship a rifle with damage or wrong parts. The people who marvel at how you could get a bolt mixed up obviously hasn't been in the shipping department at a firearms plant...I use to be at last once a week (not NEA) and I to be honest I'm surprised it doesn't happen more often.

I've owned an nea 7.5" gen 2, shot for +-10 rounds before it died. Bolt had to be properly staked afterward. It looks cool and price is right, plus I wanted to like nea being Canadian and all ---- but no. I have other complaints in the fit and finish, but this isn't a nea thread. And to balance it out I Will say that Ryan at Canada ammo offered to do any/all warranty - gun wasn't purchased there either!!!

Then I got a pws 7.5", a more expensive/higher quality brand. Before I got to shoot it, a guy beside me was using his very sbr indoors, and I was convinced the pdw was not for me, too loud and obnoxious. BUT now that I'm at an outdoor range it could be fun, not tooooo hard on the ears. Just don't have any illusions/fantasy of it being your "home sdefense" gun without a suppressor.

I don't mind 10.5"+ barrels with 556 (ala mk18), probably shortest I'd go in that caliber

Watch the EE lots of guys who still like 300blk will sell there given the economics of shooting that caliber

In closing, my next very sbr will be a 9mm. Maybe start now and save for the sig mpx or build one
 
556 out of really short barrels doesn't make any sense....

poor ballistics, nasty blast/concussion/flash and a pitiful lil hole downrange.
And you don't make many friends on the range with a 7in 556 either...and U need to triple up hearing protection.

A round that burns more/all of its powder in the barrel rather than in the air would be far preferable. 300blk ideal, 762rusky also very good. Pistol calibers perfect.
Not to mention the terminal performance and hole sizes ...whether yer paper punchin/plinkin.... or other.


If you reload which you mentioned....300blk is a no brainer. same brass/mags and firearm as 556 but all the fun and efficiency of the 30cal.

Frankly I would only shoot 300blk if I was rich and or it became the standard nato rd it always should have been.
The communists got it right with the short 762....everyone knows it...too stubborn and dug in to change direction.
 
Go with 7.62x39 if your going to go with .30 cal, its cheaper.
.300 blk and 7.62x39 are pretty much the same other then price.

The only real benefits of .300 blk is handloading availability and compatibility with suppressors(which we can't do in Canada anyway) and being able to use standard AR mags...
 
My 7.5" is awesome in .223/5.56 when I get to the range it only takes one mag to gather a crowd and two mags too clear the range and have the place to myself. It's perfect.

For clarity, it's not 5.56/223, it's the 221 Fireball as the source for cases. You can make them from 223/222 Rem but it would be a pain.
