Marines Move Closer to Making IAR New Infantry Service Rifle

[DevilDawgJJ]

I would love to see the contracts and their proposals for this.

The service published a detailed request for information earlier this week asking companies to signal their interest in producing a future IAR. The current IAR is the M27, based on the Heckler & Koch HK416

Among the criteria: The system should accept all Defense Department 5.56mm ammunition, weigh less than 12.5 pounds, and be capable of a rate of fire of 36 rounds per minute.

Here's a thread about 2 years ago on M27

36 rounds per minute?

36 rounds per minute?

How many is that for a half-second? At least they didn't ask for barrel shrouds

Lol that has to be a misprint.
I actually clicked on the article because I was sure we were talking about a new bolt gun or something lol.

If they took .303 British the it looks like the Enfield No. 4 Mk. 2 still has a chance!!!!!!

M27 has had problems with firing the M855A1 ammo.

Empirical analysis?

It's a well documented issue. A quick search on Google will bring you some info for your edification.

Here's an interesting article re. M855a1 and m27 iar reliability issues. First I read about it. Thank you hooyah for mentioning it.

I'm thinking the 36 rds/min refers to semi auto sustained fire?
Normal for current M4/M16 armourer's manual specs iirc.

Just checked. Max rate on semi is 45 rds.min and sustained semi auto is 12-15 rds/min.

Hopefully they have plenty of minutes to fight then.

Fortunately that's only a spec and not a tactic.[emoji16]
