Last fall I sold my DPMS 308 money pit and started saving pennies for a Seekins SP10.  One night I stumbled across AERO Precision and found their "AR10".  I'd heard good things about the M4's but had no idea about the M5.  Features include forged aluminum top and bottom, correct fwd assist position, receiver mounted rail, 16" melonited mid-gas 1:10 barrel with Magpul furniture.  3 weeks later I picked it up from my FFL.  Today was the first trip out and after a quick zero I fired several 3 shot groups at 100 yards with Federal Gold Medal 168 and 175.  Equipment includes Atlas bipod, Bushnell LRHS 3-12, Spuhr mount and rear bag.  Winner today was 168 with a .88"(7/8) group.

With my lack of experience I really can't say if it was the M5 or me that liked 168 most.  That said I never could get the DPMS LR308 under an inch regardless of how much spent.  The only modification I've made to the M5 is the Raptor charging handle. Some slop exists between the receivers even with a tension screw which I may try to address later. The KAC magazine works prefect while the thicker DPMS steel has to be manually removed.  The only real issue was fwd assist had no effect on the carrier in any position.  Me thinks the carrier is so tight in the upper that will solve itself in time.  Fit and finish overall is just amazing.  7/8" group on day one from a $1350 AR10 is a nice start.




DPMS on left, Knight’s on right.






KAC magazine worked flawlessly whilst the DPMS is thicker steel would not drop free.

Looks like some sort of chrome plating inside the carrier.



Gas key staked.

Nice review! I'm currently building a complete M5 part by part. I may go with a more precision barrel for hunting.  I've read on other threads about the dpms  mag not falling out on its own, the fix is shaving the sides of the mag. Thanks for the Kac magazine info!

Thanks, added a couple of photos.  I can understand DPMS going with a thicker sheet, but the dimensional change should've be internal only.  I guess my old LR308 was too sloppy to notice.

On your lower Aero M5 receiver you have a tension screw? Did they just start putting these in? Great review OP & thanks for sharing.

Glad to see the Aero barrel is actually accurate

What does your cam pin look like

My forward assist didn't work because the extractor spring had two o-rings and it was really hard to get the extractor to slip over the bullet

Cam pin look normal to me.  I'll post a pic of the bolt parts later.  Dealer told me this lower was Gen2 which has the tensioner.

My extractor has two O-rings to and makes hell trying to get the pin in and out during cleaning.

I completed putting in the lpk.  I used a dpms mag and it releases easy, not sure why yours doesnt.

Carriers are supposed to be precision hard chrome lined.  That's been standard on the AR15 since the went from hard chroming the entire carrier on the early guns, to just hard chroming the bore for the bolt.
