Benelli semi-auto rifle...

[chute2thrill]

I was wondering why Benelli or no one else has come up with a recoil operated rifle. I would think Benelli would do this off of their inertia driven shotgun and with a detachable magazine it could be a great success if it worked. I would definatly want a modern centerfire semi-auto that didn't have the problems that a gas system does..
Please tell me why this hasn't happened or why it wouldn't work...

a .300WM in a recoil operated gun??? I assume you are talking about the Benelli R1 hunting rifle and why it is not recoil operated??

What problems does a gas system have?

No I'm talking about a recoil operated gun from .223 to .30-06.. I understand that .300 WM might be a little much in a recoil operated gun but with recoil energy up to 12 gauge level? Most 12 gauges i've shot kick harder with 2 3/4 birdshot than my .30-06 does with 185gr. loads..

I'm not just talking about Benelli, I'm wondering why no one has done it with an actual rifle cartridge. I just think it would be nice to have something similar to what Benelli has going with their inertia-driven shotguns in a rifle...

is roller delayed blowback not something like that?

H&K's G3, the CETME rifles and the SIG510 have it.
also the MG42 and the Rheinmetall MG3 have a recoil operated mechanism?

Thanks Pulse.. I'm currently reading up on "Blowback" on wikipedia... I feel smarter

Benelli was going to do just that for the US military, but the military wanted to have options of hanging things on the rifle; the Sjogren inertia concept can't handle that. The gun must be able to recoil a consistant amount while the inertia weight remains stationary.

I almost experimented back in the '80s with an inertia spring from the Benelli in an M1A1- I was going to place it between the piston and op rod, with a small cut in the rod where the bolt cam is to allow it to recoil. It would have eliminated the piston, gas system and let the barrel free float. It might have blown up in my face. Just ran out of time....

Now look at the SOCOM stuff on the M14! Inertia requires ballance.

I see I see... I think it would be great if Benelli would still go ahead and make a rifle based on the inertia action.. Theres another thread going right now thats talking about recoil-operated rifles and why they aren't used in the military.. That was going to be another question of mine...
