It basically means only having to do a barrel change at the least, an upper change out at the worst...Judging from the historical record, being able to easily modify the M4 probably does not offer any real advantage to 6.5 Grendel. The last time that the US military adopted a new cartridge for the express purpose of upgrading existing weapons was immediately after the Civil War. Since the introduction of smokeless powder in 1892, whenever a new cartridge was adopted, a new rifle was also developed and fielded.

Quote:The 5.56x45 and the 7.62x51 would be the standards of comparison. How does the Grendel compare to the 7mm UIAC?IIRC, there are photos on the internet of gel tests with 6.5 Grendel/123gr HPBT and 7 UIAC/130-140gr HPBT. I don't know of any other relevant testing.
