AR upper from PSA

[65falconlover]

I just ordered a complete upper to complete my first AR build. It's coming from PSA and it's this one: http://palmettostatearmory.com/index...dle-14583.html

The specs are as follows:

PTAC 16" M4 1:7" 5.56 NATO YHM Rifle Length Diamond Upper with BCG and Charging Handle

Barrel Length 16"
5.56 Nato Chamber
Melonite barrel finish
1 in 7" twist
M4 Profile Barrel
.750" Gas Block Diameter
M4 Feedramps
Forged Upper
T-marks
M16 Profile Bolt Carrier Group
YHM Rifle Length Diamond Rail

It was $399 plus $15 shipping. Are there any drawbacks to having a rifle length gas system on a 16" barrel? I didn't ask about it but it could be that it's a carbine system with the longer hand guard. If it's a concern I'll verify with them tomorrow and go from there. I've also heard people talking about having two gas blocks mounted on their rifle. What would be the reason for that other than a place to mount the longer guard?

Thanks,

John

It's not a rifle length gas system.

It's a carbine length gas system (M4 Profile) with a rifle-length free floated rail.

Should be good, though.

I would have chosen that one since Melonite is just as good/better than C/L and doesn't reduce accuracy.

Depends how good the barrel was to begin with but......

I didn't order that upper because i didn't like the rail. I ended up with the PSA brand MI SS12G2, which is very slim and lightweight.

Its an M4 profile barrel. 7"carbine gas system.
The rail is rifle length. 12"
Your welcome.

I have 2 PSA uppers and BCGs. You got the cheap one. Mine is has the FN hammer forged barrel (machine gun steel) that is CL and I have another that is a 20" SS barrel. Good price though and I'm sure it will work well.

Thanks guys! That's what I was unsure of but I feel better now. I would have preferred the PSA upper to match my PSA lower but I've heard they don't usually sell junk so I'll be good I'm sure. It's going to be another plinker with probably a few hundred rounds a year so I'm not necessarily in need of a high dollar set-up anyways.

I'm actually surprised that they still show "In stock". Maybe things are turning around some! :-)

Thanks again!

How did you pick up on the free floated rail? It didn't say that anywhere in the description. Good to know about the Melonite, I wasn't sure about that either actually. Newbie for sure.

The gas block is a low profile gas block, and you can see it is mounted underneath the rifle length guard. Its FF because its not mounted to the gas block likke on A2 FSBs, just the barrel nut.

As for the melonite, the treatment is similar to glock barrel treatment that hardens the metal.

Unlike a hard chrome lining, which may affect accuracy (minimal anyway))

you will be pleased with that PSA upper. They may ship slow sometimes....but their products are top notch, and their prices are great !

Nice info in here! I just ordered the same one yesterday. Now waiting for my lower to get out of jail and what I hear is a long wait for psa to ship.

[sadeem28]

I ordered the same one as well, what would be our best front and rear sight options?

[cdpadilla]

I'm also looking for a sight. What do you guys think about this for a cheap sight just for range use?

PSA and PA are both GTG!
