This is a welded receiver?

If built, wouldn't this become a machine gun? "Once a MG, always a MG."

This is a brand new Bula Defense Systems receiver that the heel is cut off right behind the rear sight and the USGI heel is welded it it's place. James River Armory has been doing this now for a couple of years. I built a complete Winchester a couple of years ago. Now the TRW and I have 3 more receivers being worked on right now adding H&R, SA and anther Winchester to complete my collection of grafted M-14 USGI heeled rifles.

Not at all. Once the serial numbered rifles have been de-milled, the heels become scrap metal. The auto parts have been removed and are not used with these receivers and there is no connector assembly notch in the rail.
These are semi only rifles.

Definitely a "well-heeled" receiver!

I have seen a bunch , in person, that look just fine. Take a high resolution photograph and some look like crap. Then if the photo is posted, many that don't know there head from their butt will jump in with all sorts of negative comments. Then torches and pitchforks generally follow with the looser brigade.
This is only my second but I have 3 more in progress.

Doesn't cutting off the heel of the receiver compromise it's strength??

Shouldn't make a difference. Most of the shock of firing is absorbed by the front bolt locking lugs and op rod spring. Any remaining force left when the bolt raps the heel of the receiver "should not be a problem" as long as the weld is done properly.
I have about 1500 rnds through one that I built a couple of years ago and she is still a happy camper.
Now, if I get a flying bolt and receiver heel fragments in my right cheek tomorrow, I may have a different report.

Art, having worked in a naval shipyard and known a good number of nuclear and non-nuclear weldors and fitters over the years, it is my understanding that a properly done weld is much stronger than the surrounding base metal. Of course for any real critical welding job, non-magnetic, particle testing was performed before the item was put to use. I would also think that for liability issues, the company you're dealing with has had an engineer and/or metallurgist examine the receivers for strength and integrity.

They sure have. James River Armory knows what they are doing.

Figured as much.

Thanks.
