Questions & Answers
Purchased this kit now wondering what fits it. Looking at the Magpul PRS lite but that almost looks like it requires a carbine style tube? Expert Answer

The Aero Precision M5 .308 Rifle Buffer Kit buffer is an A2 style buffer tube and should work with the Magpul PRS Lite Stock. However, I recommend contacting Mapgul to confirm compatibility.

The description says "weight 10.9 oz" , is that weight the complete assembly, or is it the weight of just the buffer??? Manufacturer Answer

Complete assembly. Buffer Length: 5.3” Buffer Weight: 5.6 oz.

I had built an AR10/308 in 6.5 Creedmoore and it was not cycling with the standard (smaller) buffer and tube. After switching to the Rifle length buffer this problem went away and I was able to then tune the gasblock down and it runs great now.

Designed for Aero M5 Lower by Just Me in SD, August 24, 2018
I’m building a 308 using and using an Aero M5 lower. There is no mil spec for AR10/308 lowers. Accordingly many of the parts are not interchangeable across platforms. Hence the Aero 308 rifle buffer kit is the perfect choice.

Great buffer, came damaged by C lupi, Verified Owner, January 25, 2021
