Am I wasting my time?

[Mosin-Me-Nagant]

PTAC 16" 5.56mm 1:7 Carbine Length M4 Profile - w/ BCG & Charging Handle

That seems like a deal too good to pass up. I would be pairing this up with a:

LW-15 Complete Polymer Lower [LW-15 Complete (Standard)] - $119.00 : New Frontier Armory - Firearm Sales, Transfers, Ammunition, Gear and More!

That is a $408 AR minus shipping and transfer. Another option would be:

AR-15 M4 Carbine Rifle by MMC - Long Guns

This would be a new range toy and plinker. The reviews from all of them sound like they run fine and are safe. Seems like a great way to get into the AR world. Seems like I can upgrade parts if I want to or am I wasting my time on this and should just buy a nicer ~$700+ complete rifle?

Give it a whirl. If you like it keep it. I'd you don't you can sell or have a $450 AR. Too many times we put too much on what others think instead of seeing what works best. If it works for you then great. If it doesn't work out...$450 life lessons are pretty cheap! Then save up the money for the $700 AR.

I would like to know someone personally who has a poly lower..... I don't know how much I trust them for the long haul. That's just me and not trying to sway you either way.

 

[Whitsettd8]

Worth a shot but I would probably upgrade to a standard lower. If it cracks you can't get your money back.

I would only use one of those for a .22 rifle. You can risk the $450 or have more of a guarantee at $700.

I was looking into a poly lower, complete, for 120. But PSA put a premium lower decked out with MOE furniture for 169. Im willing to pay that little but more, and wait abit. I dont have anything wrong with poly, I carry a glock everyday, but Ill wait awhile, until I feel comfortable enough to get one for an AR.

FYI, this is my first AR build, so this is really just my opinion..

 

[Mosin-Me-Nagant]

I too was hesitant on the polymer lower. The reviews that I have read have seen 500+ rounds with no signs of wear. PSA has great one day deals and will be monitoring that to see about a cheap lower. Thanks for the feedback.

I got in on that upper today, although I am going to pair it with...

This receiver:

Anderson Lower Receiver

and this LPK:

Palmetto State Armory Enhanced Lower Build Kit - Black

And add a PMAG.

Upper- $289.99
Reciever- $49.99
LPK- $79.99
Shipping- $29.00
Trans Fee- $15.00
PMAG- $12.00

Total- $475.97

I will have my first scary gun for $475.97. Not bad at all and the reviews on PSA seem pretty favorable for all these parts.

You can borrow mine.

How hard are lowers and uppers to assembly together? If this something that an experienced gunsmith needs to do, or is it something that your normal person can assemble? Thanks.

f you're talking about assembling the upper to the lower it's just popping in two pins. If you're talking about assembling a lower it's simple. You need a stock wrench to put on a carbine stock. And a couple of roll pin punches makes it a whole lot easier but aren't absolutely necessary.
As for the upper it depends on how much assembling you intend to do. You need a barrel wrench, vise jaws and should use a torque wrench to put a barrel on an upper. And I'd check the headspace as well with the proper gauge(s). Installing a barrel extension (usually already installed) or a taper pinned front sight to a barrel requires some special tools as well. But the rest is just putting the right pieces in the proper places.
I'd say give it a try. Any instructions are available on line. And it's good to know the ins and outs for cleaning and diagnosis of any future troubles you may encounter.
I'd say it's easier than putting brakes on a car and that's not that bad of a job itself.

Youve never put rear drums on a gen 1 focus... Ugh.. Screw you eccentric cam..

Not sure why people tell others to do this. Checking headspace is done when the barrel extension is put on. Once the barrel extension is on you can't "change" headspacing if it's off. Best bet is to check with go/no-go gauge

For a safer poly I'd check out the omni hybrid. It's looking promising

We tell people to do this because if you put enough of them together sooner or later you'll get one that doesn't check out. And you can sometimes "change" it by swapping the bolt or the carrier. I've been putting these things together for 25 years. Most of the time they check out fine. But not always!
As far as the go/no-go gauge suggestion.......what the hell did you think I was referring to when I said check it with the proper gauges???
