Are AR15 and AR10 lower receiver internals interchangeable?

[MikeInOr]

My girlfriend's 19 year old son bought an AR10 Aero stripped lower receiver while he was still able to. I would like to get him a lower receiver parts set for Christmas so he can finish the lower. Will any AR15 lower receiver parts set work in an AR10 lower receiver?

What would be a good quality lower receiver parts set for his AR10 receiver? One that won't break the bank but maybe has a bit better than a stock AR trigger?

Everything but the bolt catch, as far as I remember. I believe the 15 catch "fits" it just doesn't have enough meat where it matters

Just buy an aero M5 parts kit and you're all set

Takedown pins are longer on the M5.

 

[MikeInOr]

I should have mentioned that I am currently an AR neophyte!

What is the significance of the take down pins being longer in the M5 kit? I have a Spike AR9 stripped receiver that I purchased in the 114 rush. The M5 kit would be good for it too? Decent trigger?

I strongly recommend using the Aero M5 LPK. You can buy them minus FCG and minus FCG/grip, but many aftermarket grips and trigger groups do not include grip screws or trigger pins. Even using other manufacturers AR10/308 LPK's can cause issues. Here's a parts list compatibility chart for general reference, but it does have a couple caveats/errors. Aero M5 is generally considerered DPMS Gen1.

Nope, the M5 bolt catch won't work in the ar9.

 

[powermad]

The grip, trigger, safety selector, end plate, castle nut and stock are interchangeable.
Fixed stock uses the same extension tube with a rifle spring and 308 buffer.
Telescoping stock uses an intermediate extension 308 spring and AR15 carbine buffers.

 

[Lasers]

Aero M5 LPK is the right answer

LaRue make a good one also, but I can't bring myself to giving that nut-bag my money.

Although there may be compatibilities, most gunsmiths say to stick with the same brand of major components when building an AR-10.

I have experience with the first two on that list and can heartily agree. CMC and CMMG have some good choices too.

I will admit to owning a LaRue but in my defense, it was a while ago and I had no idea. Good trigger, bad Santa.

 

[powermad]

I run the Centurion Arms AST in a couple.
I'll just get those if I need any more. I had to back order the last one.
They replaced BCM PNT triggers.

Don't really like the trigger shape on the Larue, don't like squared off triggers on pistols either.

AR-10 magazines will be harder to find also

We are in Oregon and the law limiting us to 10 round magazines went into effect TODAY! He purchased several AR10 magazines and has taken delivery already.

 

[Pandaz3]

Actually you can buy them today I believe, but not tomorrow. but interpretations, interpretations.

+1 For the Aero M5 parts kit. You can do it piecemeal, but the Aero parts are good and you'll have everything.

Bought some spare LR/SR magazines thru them a few weeks back @ $18.99 (for 5+).

We have a bunch, however wanted some more put up & the price is decent.

Note there midnight PST cutoff time today...
