M27A1 or PiP Concept
The M27 has been in use by the USMC for the past 15 years and for all purposes it seems very well liked and the external piston system fits well with amphibious operations at the cost of more weight forward.
The overall weight, however, seems to be an issue.
It is now 2026 and HK has done several updates to their 416 product line.
Just throwing ot a hypothetical discussion: What can/should the USMC consider for updating their existing IARs?
Some components and concepts that I think will remain:
Existing upper and lower receivers
16.5" barrel for velocity
Bayonet mount
Some parts for consideration:
Change the handguard to the 10.5" 416A5 QD. The 13-15" wouldn't allow for a bayonet.
Change the stock to something lighter.
M-LOK vertical grip
Something more modern than a Harris bipod
Change the charging handle to the ambi one.
Possibly an ambi safety selector
Possibly an ambi magazine release
Does anything he the handguard, grip or stock come with an FDE treatment? Or just future rails and grip covers.
Love for a discussion, what am I missing?
