Are you switching cartridges?
My answers are
Don’t worry about the gas system now. It can and probably will work. If it doesn’t then just go from there.
The BCG can work but I generally frown upon using the same BOLT in different barrels.
Many answers have good reason behind them and others may have nothing behind them other than one isolated incident or flat out superstition.
no, staying with 5.56x45.
I WANT to keep it relatively simple. pull pins, swap out uppers, and push pins, shoot.
I was thinking Palmetto State Armory but your post got me to go look. Bear Creek has some very reasonable deals going right now. I've never owned a Bear Creek Armory upper or rifle but a friend used one of their uppers for an AR-10 build. I have shot his rifle. I like it.
I have one and use a rifle (A5) action.
Good deal on a BCG too.
I've not used any Bear Creek parts either (I'm in no way affiliated ), but I do know that with guns in general and AR's in particular, you often get what you pay for, up to a certain point. For a range toy, or for the thing that most folks use their AR's for (leaning in the corner of a closet) quality is basically irrelevant. Have to determine what you're buying it for.
Get a complete upper, with bcg, and you're good to go.
Just keep in mind that the recoil impulse is a little more pronounced with the shorter gas tube, also the shorter barrels often have a different twist rate, tuned for 62gr. bullets usually, and that upper may like different ammo.
For my 2¢, just get a "complete" upper, so, you get a BCG with the upper.
If possible stick with like-for-like, so get the same rifling twist rate. Again, for my 2¢, match the fore ends, too--free float v. delta ring; with or without FST, etc. I find you'll wind up with sight to match, too, rather than having dismount one to the other. That really makes it plug-n-play, pull the pins and just swap.
Now, in all fairness, ask the question on arfcom, and there will be a flamewar on buffer weights and gas lengths. To my mind, barring large changes in caliber used, is just arguing how to go from 99.9% equal to 99.95%. That, it's really the same number of angels on the pin head, and they are arguing about how many cherubim you can get in too.
Now, fair warning--having a upper in the safe can cause lowers to appear. That's usually where customization to a specific use or user occurs.
If you still want to just go the upper route, I would buy one with the complete BCG... don't swap bolts. I always recommend a mid-length gas system on 16" barrels... just my .02 worth, although I'll say most carbine length systems work well enough.
Having said that... here is a Daily Deal at Palmetto on a carbine-length... at $270 with BCG???
Rifle on the left is the Palmetto kit...
+ 1 on this upper. I have it and it runs great. It is lightweight and accurate.
I get an individual BCG for all my uppers.
I am running a 22-inch rifle length 30RAR on a standard carbine receiver extension spring and standard weight buffer.
Having a properly regulated gas system (ie gas port size) is most important.
Technically this would be illegal without an SBR tax stamp since his lower has already been assembled as a rifle.
I know, I know, no one would know.....but they would still need a "brace," and ATF has been rumbling about cracking down on those as well lately.
The 11 inchers (and shorter) start to get ridiculously loud too, without a can anyway.
The OP would have to get one that has a muzzle device pinned and welded to 16" OAL since he is wanting a second upper for a rifle.
No one else mentioned SBR's until you did.
OP was asking about 16" uppers.
And the tread drift has begun. The OP is specifically asking about a 16" upper.
@x_wrench You will be better off buying a complete 16" upper that comes with its own bolt carrier group. While it is normally okay to swap bolts, it is not recommended since issues can pop up.
I suggest watching Palmetto State Armory. Their Black Friday deals have already started. While they maybe more expensive than Bear Creek Arsenal, You will get a better quality upper along with better customer service.
I like PSA products & own one of their AR's & one of their Dagger pistols. Bear Creek has a complete rifle for under $400.223 Wylde, 16” Parkerized M4|New MLOK|Rifle (bearcreekarsenal.com) or just the upper for a little over $200. 5.56 NATO, 16” Parkerized M4|New Handguard (Spiral Flash Hider) Upper (bearcreekarsenal.com) They also have a 10% off promotion on their site.
I am not saying what the OP should buy. That is up to them but there are affordable options out there. I would suggest taking their time & doing their research.
Better in what way? Fitting it in a backpack to take to the gym?
Something you have to clear those lockers rooms
I want NOTHING to do with a SBR! The Gov't already knows more about me than I like them to. Ideally, they would know NOTHING!
