ar 15 question (dedicated lower for multiple uppers)

[digdeep74]

Does anyone here on the forum have a dedicated lower for multiple uppers?
I dont see the point in having two full rifles since i can only fire one at a time and changing them out is a cinch.
Dont be shy people let me know why you feel the way you do!

Don't have multipule uppers now but probably will in the future.

As soon as I can, I'm getting a dedicated Spike's .22LR upper.....and maybe eventually a 9mm upper......and if it turns out to be as cool as the marketing hype, eventually a .30 Remington upper (if it ever actually exists).

I just got a 20" doublestar flatop upper and have 2 complete rifles now but would be just as happy with swapping the uppers out for different applications.
Im thinking of selling the other lower to fund some other stuff.

OP, multiple uppers to one lower is fine just make sure you ALWAYS use different BCG's even if the caliber is the same.

So, you should purchase new BCG's with each upper.

even in todays market the lower is the cheap part of the ar, in my mind it's too easy to spend another $300 and piece togeather another lower to go with your uppers

I didn't vote because it isn't yes/no. See what Krochus said; this is also my view. If the uppers are different, you may also want a different trigger, grip, and/or buttstock to match up with their intended use.

In addition, if there is a repeat of the 1994 AWB, any upper without a lower would only be useable on a lower that was consistently equipped with an upper having the "evil" features. For instance, if you had a 16" M4-style upper with a flash hider and bayonet lug, and a 24" varmint upper with neither, arguably putting the varmint upper on your one lower turns it into a non-AW and prevents you from ever putting the M4 upper back on. Maybe I'm being paranoid here, but for around $300 extra you'd have multiple rifles, in fact and in law, and all would be grandfathered if there's an exact repeat of the 1994 ban.

yea i have two bolt carrier groups as well.
So i was planning on using the both of those.But just out of curiousity why the insistance on using twodifferent bcg?

Need more than one so my wife, brother, dad, etc. can shoot simultaneously with me.

Our club has uppers we use for the NTIT (Rattle battle) at Camp Perry. They see a lot of rounds really fast. It's nice being able to plug the loaner onto your existing lower. Besides, good triggers can get spendy in a hurry.

 

[spartywrx]

If you're going to drop $500+ on a new upper, you might as well get a lower to go along with it (an extra ~$200 at today's prices). Friends may want to shoot with you, AWB implications, and its fun to collect serial numbers!

But to each his own. Some people prefer one way or the other.

I didn't vote on this,but had you worded it: Does (owning) one lower for two uppers make sense?
There would have been a yes vote from me..Then I'd have referred you to krochus post # 7

 

[dscottw88]

I know people who pick up extra uppers in different calibers and all, and although it works, they just end up convinced that they need another lower to slap on it. I figure, you can never have too many lowers. So once I build one up, I move onto the next, each being unique in their own way.

Since an upper is the expensive part of the gun I say no. I would rather have decicated lowers for match/varmint gun and cqb carbine lowers because they will have diffrent stocks and accessories depending on what there being used for. Just muy .02

 

[nhm16]

I have two lowers and four uppers, but mostly because I have a two "carbine" type uppers, one each in 5.56 and 6.8, and similarly two "long barrel/precision" in different calibers. Similarly, I have a lower with a collapsible stock and a lower with a Magpul PRS.

However, I am tempted to get another lower just because the "Cal 5.56mm" rollmark on my lowers bother me when I have a 6.8 upper on them

I don't anymore but used to use a varmint upper with a 24" Shilen on the same lower that I used for my NM upper because of the trigger. It was a fine match trigger but the varmint gun was too heavy for much other than prairie dog popping. So I had a good trigger in two accurate rifles. I gave a yes vote because that really made good sense at the time. Each upper had it's own BCG and I go along with the need for it. Headspacing, unless I'd built both myself and KNEW one group would be right in both.

Now I've got seperate lowers for each upper but don't have the varmint setup any more. Just two carbines and my Vietnam "homesick" replica. One of my carbine lowers is marked "CAL MULTI" so I've been thinking about adding a .22 lr upper for that one.
