Just to clairify a small point on the SBR/AR pistol thing. There are pistols, rifles and other firearms. Any AR lower sold as "other" or "pistol" can be made into an AR pistol, SBR (with appropriate paperwork) or a standard rifle. However, any lower sold as a rifle can not be legally converted or made into a pistol. Once its a rifle, its always a rifle.

I don't want to see anyone get in trouble.

Edit: if you are buying an AR lower to build it as a pistol, all you have to do is ask the FFL to list it on the sales paperwork as "pistol" or "other " and you're fine. If they mark it as rifle or if it is a complete lower sold from the manufacturer as a rifle lower... You can't make it into a pistol.

I finally found some time to dial in the optic on my CZ Phantom. I sent it off to Cajun Gun Works for a Pro Package and to have the slide cut for the optic. It is now the most fun pistol I have ever shot. The DA is around 7 lbs and the SA is around 3 and both are silky smooth.

Here is the result of the first 50 rounds:

I bought a cz75 tactical a couple months ago. I have been thinking about sending it to Cajun Gun Works. Were you happy with the before and after?

It was a night and day difference. The Pro Package was worth every penny. Before it was worked, the trigger was horrible, I think the DA was around 11lbs. Now the trigger reminds me of my 1911 (2.5lbs) and is my favorite pistol.

This is my AR15 I partially traded a mustang for. It is chambered in 7.62x39. The guy didn't have enough cash to make me happy so he threw this in. I was kind of worried it might be finicky, but I figured if it was I would convert it to 5.56. After two months of owning it I finally had a chance to shoot in today. It shot great with no jambs or miss fires. I used 10rd mags today, I didn't even

try the 30 round mag because he said it tends to jamb.

You can convert a 7.62 lower to 5.56?

From what I understand, 7.62x39 is the same lower as 5.56. I would have just get a new upper.

From what I have seen from my friends adventures.. an AR that fires 7.62x39 out of 5.56 mags are very unreliable. Like 5 to 7 shots reliably. You have to buy an "AR looking" rifle actually built for 7.62x39 and AK mags if you want it to work right.

It sound like someone tried to do a 7.62x39 AR build on the cheap. If that's the case, he can swap uppers or change the barrel and BCG.

AR Stoner are the only reliable mags. I didn't have any problem out of the 10 round mag. I didn't try the 30 round as he said it was not reliable unless I keep it lubricated. It isn't unreliable due to the feeding action. The bullets themselves drag in the magazine. As long as the 30 round is well lubed with silicone spray it will fire with no problems.

The other thing that makes them unreliable is the firing pin right out the box doesn't engage the primer enough. The builder took 15 thousands off the shoulder so the pin fully engages the primer every time.

The reason why 5.56 mags don't work well has nothing to do with lubing the mags. followers should be able to run completely dry. If you are lubing them... something is wrong.

On a 5.56mm/.223 Rem mag, there are bullet guides inside the mags that aligns the .22 cal rounds to hit the feed ramps at the right angle and position. The guides push the .30 cal projectile of the 7.62x39 to far into the center of the mag, putting excessive pressure on the rim of the cartridge, basically binding the cartridge in the box magazine and having it misaligned for when it hits the feed ramps. On PMags vs. metal mags... PMags swell since the plastic is flexible, but them you have issues inserting the mag. The more rounds the mag holds and the more ammo you put in the mag, the steeper the pitch of the cartridge is at the bottom and the less likely it will feed correctly.

Tossing a bunch of lube at it, just hides that fact that the whole setup is completely wrong. That's why companies started making 300 Blackout mags. They saw people modding PMags by grinding the guides down, so Magpul just starting making them that way.

Now that I think about it... you may have great luck with a 30 round 300 Blackout mag from Magpul.
