Hi,
I need to identify 2 uppers and try to put a value on them.  Hoping for some help, as I'm clueless.  I googled a bit but couldn't find any resources to help me.

First up is a 20" A1 style upper.
- triangle handguards
- barrel marked CMP 5.56 nato 1/7
- barrel profile skinny under handguards (is that called govt profile?)
- front sight tower has a C on the right side near the top.
- There is also a bell-looking mark on the right side of the gas tube area at the front sight tower.
- Has bayo lug and a flash suppressor with no slots on top.  It's not on perfectly straight.  A2 installed upside down?
- Uppper receiver has P and M marks on right side.
- Does have a forward assist but no brass deflector.

Number 2 is an A1-style with 24" barrel and floated aluminum handguard
- barrel marked only  5.56
- barrel is same diameter under the handguards.
- Has a flash suppressor with slots all around
- Has a bayo lug
- No markings on right side sight tower.
- Left side sight tower has an M looking mark.
- Upper has forward assist, no brass deflector.
- Upper receiver has L and M markings.

I bought these uppers as a package deal with an Oly stop sign lower receiver.  I was lead to believe the 24" upper and the Oly lower were purchased as a complete rifle and the 20" upper was purchased seperately.

Any help identifying these pieces?  Thanks!

Is this the wrong place for questions like this?  Is there any info anyone can point me to to help me identify these?  I can't seem to find anything online.

Thanks.

these sound like "put togethers" and not factory.

first upper-Colt gov profile 5.56 1/7 twist, A1 barrels were 1/12 twist
sounds like f/h is upside down, probably a colt sight tower
upper receiver is Colt M16A1

2nd upper-another Colt M16A1, unsure of sight tower, barrel ect.
