upper recievers

I was contemplating a 16" HBAR as it seems to be the longest while still keeping it a carbine. I'm trying to dig up an article I had a couple months ago that compared all companys m4 carbines side by side and ended up with a list from bottom to top. Stuff like colt and lmt were at the top and it was interesting to see stag sitting on the bottom. I see a lot of love for them on this site. Not trashing them just interesting to read. A stag bcg is 175 and an "enhanced" lmt fa bcg from questar was around 350. Would someone have a noticable accuracy difference?

I believe the biggest change to the "enhanced" is a chromed bolt. If you clean your weapon properly, this should be a superfluous feature IMHO.

The stag bolt is milspec, MPI, and shot peened. It's good enough.
 
Here is what I suggest. for a budget AR. The money you save you can buy a decent optic.

Aero upper-lower, BCG and LPK from Armseast.
Barrel from SFRC
all other parts from Brownells.
 
Guess my thought is that my 20" is accurate enough, it is always wind drift that is the problem.

I have been forced to shoot a carbine against rifles in competition and would never choose to do it again. Like I said we will see at NSCC.
 
If they are in Spec a bolt carrier assembly is a bolt carrier assembly. No big difference in accuracy.

As for durability some manufacturers proof their bolts with over pressure loads. This will cause bad bolts to fail (never happens as bad bolts get caught by NDT first) and good bolts to lose half their life. Stag gets a finger wagging on many lists for not proof testing but Kevin B from KAC has stated that proof testing drastically reduced the bolt life of the M110, however they must do it to meet the Spec.

So is the Aero complete upper the cheapest in Canada right now?

It's the cheapest DECENT stripped upper in Canada right now. I have done two builds on them so far and they work 100% - good to go. You might be able to get a non-M4 feedramp upper from the Korth Group for $5 or $10 less, but the AP is a nicer upper.

Now that being said, an UPK will run you around $40, so for around $155.00 you can go the AP route, or from now one, you can get an NEA billet assembled upper receiver for $179.99.

I would suggest to you the NEA upper will be the better value once they start shipping.
 
Guys, they are here and being assembled. We expect to ship to dealers no later then friday of this week. The internal receiver has been dry film lubed, which you will find makes the gun much smoother then uppers not coated in a similar matter.
