[ARCHIVED THREAD] - Aero M4E1 and AM-15 Question

Posted: 5/26/2017 1:43:31 PM EDT

I have an extra Anderson AM-15 sitting on my bench and I'm building a range beater. Something that will run true but can be thrown in the bed of the truck and take some mild abuse. I was looking at the M4E1 (granite ridge combo) with a gen 1 or 2 handguard; and wanted to know if anyone is running this setup. Is there any excessive slop or wiggle or is it pretty tight? Thanks

The aero precision M4E1 had three samples selected without solicitation by Crane for testing and comparison of mlok vs keymod strength and return to zero.

One of the samples of the three exhibited the greatest strength before failure of all rails tested in both keymod and Mlok strength.

Sample A3/A6 was a aero precision M4E1

Having direct experience with this rail, once it is bolted to the integrated receiver extension it has tight lockup and has not exhibited loosening of hardware. I utilize rock set for the hardware and have not had a product failure to date.

Thanks for the response and great information. Are you running an Aero lower? I'm gonna be running an Anderson and was wondering how snug it will be.

Thanks again

Im running a palmetto state armory lower. Fit is typical between them. Nothing special.

I think fit is hit or miss no matter what brand. Matching or not matching brands. I have had the best luck when buying match sets.

What I figured. I think I'll just see what happens. Worst that happens should be just a standard fit

Thanks guys

I have 2 m4e1s and a third on the way. They're tight no slop, and a 9 year old with a torque wrench can assemble the upper in 15 min. I'm a big fan.

I have two, one on an Aero(gen 2) and one on an Anderson(gen 1). The fit with the Anderson is actually better. No slop while the Aero has some play. Aero does have a tension screw I didn't use.

I have a few aeros and they are awesome. One is a COP and another is a m4e1. The m4e1 is a great rifle and the fit and finish is great. The rifle has not let me down yet and is my rifle that takes the most abuse. The COP is one of my oldest rifles and is awesome, but not mlok and its a bit short.

My only complaint about the aero system is that the HG diameter is on the larger side. Other than that, the one I have is great.

That's really the only complaint most people have. I like the handguard diameter and it's really close the the plastic clamshell type handguards. Plus if you plan on going suppressed SBR they're great for shrouding the can. I have a friend that bought one because he liked the design and another might be picking one up because the ID will shroud his can nicely.

Thank you. I'll post some pictures when I finalize the build.

Love my M4E1 upper. Im running mine on an Aero gen 2 lower with the tension screw in the base so slop between upper and lower is a non issue. My rifle has never had an issue and shoots sub moa. Im actually thinking about replacing the 556 barrel with a BA 6.5 grendel

I have two M4E1 uppers. One on a BRO billet lower and another on a Seekins precision ambi lower. Excellent fit and zero slop on either.

I have an M4E1 upper on my precision rifle and love it.

Great looking rifles guys

Thanks for the input

Here are my two Gen 1 uppers, I have a gen 2 on the way with a 12" handguard for another 5.56 upper.

I have two; one on an Anderson and one on an AP lower. They fit, same as any other upper/lower combo, easy to fit together no excessive wobble. As to how tight or loose that depends on the tolerance of those particular items.
