So many choices!!!
Decided I want to go mid length instead of carbine to eliminate the notch in the barrel. ( I think I have elimated the carbine because from what I have heard around here since we are not in the military why bother with the carbine since the cutout is the weak point of the barrel???)

BUT-as I understand with a middie you get more durability, accuracy, and reliability. Is this correct?

Second can't decide if I want heavy barrel, Classic which I am guessing is in between, or the light barrel. ( I will pretty much just using this as a range gun)

Looks Like palmetto has some uppers that have lead lapping I understand this is very desirable, any opinions on "lead lapping" ??

Lastly does the m4a1 reduce acuracy because it is two layers of chrome, and is this really needed???

thank you

This is my Palmetto M4A1 CL CHF carbine. It has been flawless and I find it to be accurate at least more than I could be. http://i1067.photobucket.com/albums/u431/saenzrich/IMG_6645.jpg

These targets were shot after I zeroed my Vortex 1-4x4 on magnification 4. I used cheapo Wolf WPA 62gr. HP and aside from the occasional flinching flyer here and there I would say it is accurate and reliable for me.

My thought is if the double chrome lining and cold hammer forging of the barrel affects accuracy I couldn't tell much at all. People swear by it but if your going for just plinking it shouldn't affect you much.

Sweet! Looking to build my own PSA rifle soon. Saenz, looks like you went with the MOE furniture option which is exactly the one I'm looking at. I was originally looking at the hammer forged gov't profile middy but will probably go with the hammer forged light weight middy instead.

I would recommend them as good to go. They are very busy and the wait is a little longer than most, but they seem to put out quality goods. I don't think you could go wrong with either one.

I think i waited about 3 weeks for my 20" upper. Totally worth it. It's a nice rifle that resulted.

I've not seen it affect accuracy either way. On a 16" bbl the mid length gas system is less abusive, but you'd have to have to spend thousands of dollars in ammo to tell a difference. Reliability has many factors beyond gas system length. Things like buffer weight, extractor setup, gas port size, and carrier weight. Midl ength gas on a 16" bbl typically has less perceived recoil, and is referred to as softer shooting.

Mid length gas on a 14.5" bbl (you probably know you can get these with a permanently attached muzzle device to avoid NFA issues) can actually reduce reliability. The idea is for the setup to be extremely soft shooting with full 5.56 NATO power ammo. The action short stroking with standard to light .223 ammo is fairly well known.
