Default Advice on an upper

So I am looking to either purchase or put together an upper. I am thinking a 14.5" with the comp welded so I don't have to worry about a stamp. Mid length gas system. The questions I have are.. What twist, and why? Any particular uppers to stay away from? I am also trying to keep it light. It will be going on a stag lower with a ctr stock

In a perfect world, there would be an abundance of quality 14.5-16" ML uppers with 1:8 twist barrels. That is the ideal twist in my opinion (shoots almost everything really well), but unfortunately you don't get to live in that perfect world. The vast majority are either 1:9 or 1:7. So you may need to decide which better suits your needs. Either answer can be plenty good.

On the cheap, I think M&A parts inc has some good stuff to offer. Complete barreled uppers (sometimes even 1:8 I think) for like $450 with a decent BCG and CH included.

For a little more, shop around at PSA and BCM. PSA is probably where you'll get the most bang for your buck IMO. That's why they have so much of my money. BCM is a little trendier and offers great products with quick service.

I wouldn't bother with anyone else. There might be other good options, but these three have solid track records and extremely fair prices.

Just went and talked with LGS and I think I am going to go with a stag. 14.5" pined and welded comp, 1:7 chrome lined. $535 ish. With low profile gas block and a quad rail.

ive never understood going 14.5 then tacking on a muzzle device to hit 16" why give up 1.5 inches of barrel if your not going to sbr it??

My 14.5" BCM build is noticeably lighter and tighter than my 16" DD. Shoots as well or better for me too, BTW. Both are midlengths, both are excellent guns.

The ideal 'do-it-all' AR is probably a 16" ML. No arguments there. That's just sort of the design that does everything well enough. But I do love my 14.5". If I could take only one of my guns to survive the zombie/robot/alien apocalypse, I'm actually liking my $1400 build over my $2000 DD. I value the compactness as well as the weight...just a shade north of 6.5lbs...with a red dot, BCM BCG and ambi CH, and BADlever included.

16" middy is probably the ideal/versatile/vanilla option, but 14.5 can be pretty cool too.

Build one my friend, and I suspect you may become a convert.



BCM 14.5 + Vortex Sparc


DD M4v3 + EoTech XPS 2-0

i dont like the idea of permanent anything on a part that is supposed to be removable.

ive shot 14.5 sbr rifles and i cant tell the diff tween it and a 16" barrel.

im not saying you shouldnt do it or are dumb for doing it i just dont understand it heh

There is no difference between a 16" barrel and a 14.5" barrel as far as accuracy is concerned. In my professional opinion you should stay away from 14.5" barrels and stick to 16". Of course 10.5" and 7.5" are good to go as well. See the bottom of my signature.

I have a 14.5 barrel with the welded on flash suppressor. I wished I would of just got the 16 because you can't change out the gas block. To modify or change something on your barrel later on your going to hate that problem
