Monday morning I talked myself out of hitting "add to cart" button with some of the Daily Deals for my first AR build.
While out and about I started wishing I had ordered these parts, so I got back to my computer to do so and they were already sold out. I browsed the remaining sales and purchased a complete upper and a complete lower blem for a total of 586. shipped. I got my confirming emails from PSA :) http://palmettostatearmory.com/index.php/ar-15-05/complete-uppers/psa-16-mid-length-cl-mp-premium-upper.html Please pardon my ignorance, but the description reads: PSA Premium 16" 5.56mm 1:7 Mid-length Modified A2 Profile - with BCG and charging handle; my question is, what is it that is modified with this? Question #2: I also ordered a complete lower blem ("Classic Edition"), does classic edition mean AP, LW, SC, or other style? Any guesses which type I'll be sent? Thanks for the patience, new here, not good with computers. After some time with the "help" files I may post up pics of my old CDaly CDD-15, 20" HB style A2 (shooter and safe queen). Now for the 3-4 week wait on my upper and lower. |

I believe the barrel is thinner (like a penicl barrel) under the handguard up to the Front sight post. Then afterward it gets thicker to the tip of the barrel. I think the concept behind it was to have a more rigid barrel in the part likely to encounter abuse (dropping rifle, hitting barricades..etc). It was a way to increase durability of barrel while still keeping some shaved weight.
As for the modified part, It has to do with the cut/angle in the transition from the thinner portion under the hand guard to the thicker portion at the FSB. If you search barrel contour / profiles you should find all the info you need. (more in depth with pics). |

Here is a pic to help. Notice the A1 is thin all the way through, and the A2 gets thicker. The modified refers to the area where the barrel gets thicker, its just a different angle/cut. http://img263.imageshack.us/img263/4373/profilea2a1la4.jpg I never would have figured that out, thanks so much, appreciated. |

I thought A2 meant a rifle length gas system with a 20" barrel as in the original A2 configuration (which I always thought to be a rifle). |

A2 to my knowledge =20" I can get the profile difference after the FSB, but it should be 20 inch as well. |

I look forward to it. |

I have an older Charles Daly A2 already.
It's got a 20" heavy duty barrel and the carry handle built into the upper (not removable). The upper I ordered showed a picture without the carrying handle (what I wanted). 
I was starting to worry that the advertised picture was simply generic (without the carry handle). Now I'm wondering why they are calling this upper an A2 style vs an A3 or M4 ? What other differences might there be that distinguishes an A2 upper (other than barrel length) ? 
I ordered a Vortex Strike-Force to mate up with this upper and hope I have no issues. Appreciate all the help fellas. |

From what ive read the true m16a2 is a 20" government profile barrel, with an A2 upper receiver (fixed carry handle and redesigned rear sight) along with caseing deflector, and forward assist, being round. The inside of the A2 upper would not have feed ramps either. |
It is not an A2!
|
It should just be called "Gov't profile", since that's always meant light under the handguards and midweight (just under .750") out front. It really has nothing to do with "A2", and A2 doesn't designate a barrel profile.
Palmetto used to call it "Special A2 profile"- http://www.ar15.com/forums/t_2_301/215667_Special_A2_profile_barrel.html |

It's 16inch (not 20inch) with a mid-length gas system (not 'rifle' length gas system) and does not have the M203 cut on the barrel.
To throw in my two cents, I think that modified A2 in the ad mostly means 16inch with no M203 cut since the ad specifies that a mid-length gas system is used. It sounded good enough to me that I ordered one (which is on it's way). Forrest |

If my memory serves an A2 does not have a 203 cutout. I could be wrong. Calling a barrel an A2 would suggest to me a specific barrel type such as the m16a2 barrel spec. You're correct about the A2 barrel profile and no M203 cut... Although I obviously did not state it well, my point is that this item has a modified A2 barrel because first, like the A2, it has no M203 cut and second, unlike the A2 (the modified part) it's 16inch (vs 20) and a mid-length gas system (vs the A2 rifle gas system). I'm also guessing that the barrel profile of this 'modified A2' barrel is heavier under the handguards (than the A2), but that's just a guess until I receive this item (Tuesday). Forrest |
