Guns, Bows, Shooting Sports, and Hunting Colt competition crx-14.5 Anyone have any experience with the crx series yet?

[Flying_gage]

Have the opportunity to pick one of the above up for list price. Seems as though this is a pretty new model as there is very limited info out there.



Here is a link to the basics via another shop:

Not looking to hang a bunch of farkles off it, hunt zombies or use for a defensive weapon. It is a fun round to shoot and that is what I plan on doing. Also a good varmint/critter round.

 

[The patriot]

Is 2K the list price?
If not what is?

Edit: I'm thinking around 1100

 

[Flying_gage]

List is $1349 or there abouts. That is what I would pay.

 

[The patriot]

I'd get it if I had the extra $$$.

Edit: AGS armament has em for $1299

Do you need a stamp since it's a <16" barrel? I couldn't find it on Colt's site.

No it has the brake pinned which then brings the total length to the 16. 1" requirement. I have looked everywhere too and can't find anything.

Under the present political circumstances, if its directly available and you want it, buy it!
Is it chambered for the 5. 56 Nato, . 223 Wylde or the . 223 Remington?
The first two are interchangeable. The second limits you to commercial . 223 ammo. No 5. 56 NATO.
The price for a genuine Colt is still reasonable, again under the present political climate, IMHO!

I believe Colt chambers all it's semi auto AR types in 5. 56 NATO.

That is my understanding.

 

[GHarman]

Course, the AR's are modular, but, it does say . 223 on the lower receiver in your link above and the head liner says . 223 Wylde?

Just dont assume! OH! "Farkles" :-laf hangin on it are COOL!Oo.

I thought the Wylde chamber works better with both than the 5. 56 with the . 223. Does that make sense? Either way, I'd get it.

 

[The patriot]

Wylde is supposed to be able to digest both 223 ans 5. 56 NATO fine.
My understanding is it's slightly tighter than the std 5. 56 chamber, but has the leade so that it can be used with 5. 56 pressured ammo. It's like a target version of 5. 56mm.
It's also GTG if youre planning on using the sierra 80 gr bullet single loaded.

 

[HHhuntitall]

The 5. 56 and . 223 are very similar. With sloppy machine work from modern manufacturers, I'd call them interchangable, except for one thing... . The throat and lead going into the chamber. This is where the pressure spike happens, and where damage starts... the . 223 has a noticeably shorter throat, so the bullet enters the lands quicker than in the 5. 56. 5. 56 has a longer throat and less steep lead, so the bullet has a longer "jump" before it hits the lands and begins to build pressure, so the loading can be hotter, as there is less of a pressure spike. Using 5. 56 ammo in a tight . 223 chamber can cause excessive pressure due to the hotter loading, the bullet hitting the lands quicker, and the ensuing pressure spike. It also makes for some good photos on FaceBook and TDR of what used to be your rifle and where your fingers used to be.....

 

[AMink]

You can shoot a . 223 out of a 5. 56, but not the other way around. You can shoot a 7. 62x51 out of a . 308, but not the other way around. Follow what's stamped on the barrel. My LR308 says both.



With the way ammo is right now, it might be a moot point!

That's no lie!!! I had to back off on my reloading, as bullets are getting harder to come by, in bulk anyway. Luckily, the Bergers are still available here and there. I like to keep a few on hand, so I've been ordering a few, as I've shot so many with hunting season going by..... And Sierra seems to have plenty on hand, althought I've noticed a lot of them have dissapeared in the last few weeks..... along with powder!! Reloader 25 and 19 have dried up.



On my chambers, most of my reamers have a long lead for match use or longer OAL for performance, so they work in most auto loaders, too. The key to accuracy, in my experience with ARs and M1As, is that initial jump to the lands(to prevent pressure spikes), with minimal neck lateral movement of the case to keep the bullet straight down the bore..... Handloading helps a lot, too, as most commercial ammo is not near as consistent.

 

[Flying_gage]

My DPMS is stamped for both, (. 223 and 5. 56). Yet is it a good idea to have both in a single system? It is my understanding that Colt is chambered for 5. 56. Is this correct?

 

[HHhuntitall]

What's the barrel stamped for? The upper is what's correctly labeled for chambering. I had a . 223 Lower that was chambered in . 243 WSM.....

Remember, Modular, Modular, Modular!:-laf

The AR is a true example of relativity in the modern world, It "can be any thing ya want it to be"!:-laf

I would really be asking questions if my upper receiver looked like this

http://www.brownells.com/rifle-part...e-50-bmg-24-bbl-sku100005530-40862-76850.aspx.



All in fun, of course! Oo.

As mentioned, the 5. 56 chamber is more generous in the throat dimensions. One other issue is that the 5. 56 MM NATO is loaded to 60,000 PSI chamber pressure.

The factory . 223 Remington is loaded to a SAAMI spec. chamber pressure of 50,000 PSI.

That being said, I will certainly defer to HHhuntitall and Patriot for their expertise with the modern AR rifles.

My question is; Flying_Gage, HAVE YA BOUGHT IT YET??:-laf!

That upper uses the same pressures..... Just a bigger bore and a weeeee bit more recoil... .



Oh, and GHarm!!!!! SAAMI specs are 55,000psi on the . 223, but in Europe, it's rated at 62,500psi (430 megapascals) Interesting, eh? I wonder, does that include Canada?!??! I only state that for interest purpose, not to be argumentative!! We both know the same amount of metal is in either chamber!!! Regardless, they'll only take as much as they will take!!



..... and GHarm has the Million dollar question!!!! Well, $1500 question, I guess... ... . :-laf

 

[RVTRKN]

My AR will only see . 223 rounds. People try to sell me 5. 56 all the time telling me there is no difference.
