Aug 15, 2018 · Getting parts together for a 6.5sst upper build and wondering if there is any measurable difference between the M5 and M5E1 as far as strength/rigidity and/or isolating barrel from handguard flex. Here’s how I got here. My usual routine is get an M5 upper and send it to mike at Dtech for...

Looking at M5E1 uppers and it seems somewhat similar to the Larue system (but much less precise of course). Does anyone have experience with changing barrels on M5E1's and trying to do a poor man's barrel change? I'm not expecting 0.5" return to …

Feb 22, 2019 · It looks like the M5E1 enhanced is the upper with the extension on the front to add the Gen 2 MLOK hand guard (8 exterior screws) and they just put the same description for the ATLAS S and R erroneously.

Jan 23, 2023 · The cons to the Seekins are the availability, cost, lack of handguard lengths, and lack of forward assist which is a personal thing. I prefer them to the aero m5e1 sets anyhow. Finding a SP10 builders kit will be your biggest hurdle. Either would get the job done.

Jan 20, 2022 · Hello. I recently put together an Aero Precision m5e1 chambered in .308 win. It has an 18" barrel with a rifle length gas tube. Mil spec carbine lower. The upper I bought complete and I put together the lower. Everything is Aero. It fires and ejects properly but it won't pick up a new round. My...

Jun 5, 2020 · I'm new to the AR10 platform and just picked up an Aero M5E1 upper and lower. I'm not happy with the amount of play between the two. I have ordered one of the set screws that goes through the bottom of the lower to supposedly fix the slop, but that seems like a rough fix. Does anyone have...

Jan 23, 2024 · Hello everyone, if you would be so kind, could you tell me please, what are your experiences with the Aero Precision M5e1? The one with the 20” stainless .308 barrel ready to go from the shelf, to be exact. I guess it’s best to describe my requirements at first. The rifle should be used mostly...

Dec 13, 2019 · I bought just the M5E1 tool for $37.50 from G&G. It arrived quick! And this is my first build (still waiting on a Criterion barrel to arrive) so very interested in this topic. There are a lot of threads that simply ask if the AERO M5E1 receivers need lapping, in other words, is AERO machining beyond the norm.

Feb 8, 2019 · I built my 6.5 M5E1 using a standard aero non adjustable gas block and the normal rifle buffer and A2 style buffer tube. Feeds everything perfectly no problems at all.
