restoring an original XM607 stock

Some years ago, a good friend ( who was in the scrap/junk business) found some early Colt
plastic furniture at a salvage yard. There was one incomplete Colt XM607 stock. Production figures are very small on this extendable stock. A company called Total Silence produced a
really nice reproduction of this XM607 stock, providing some the internal parts to complete the original. Note the original color of the XM607 stock is gloss black.

:thup:

So how do you rate it's functionality? Was it just before it's time or does it have serious downsides?

The early Colt extendable buttstock is complicated with all the parts used to reduce the length by only 2.7 inches. Also it is slower to operate the adjustment because the lever is located inside the rear of the buttplate. This was the first attempt to be able to reduce the total length.

But it is more comfortable because your cheek is always on the plastic buttstock. I find it
very handy in the reduced position over the later telescoping buttstockAttachment 15851Attachment 15850

That is some amazing and hard to come by furniture. I don't know of a single original 607 stock on anyones builds. All of the fellows that have put together 607 style rifles that I know of have used either TSI or my65pans reproductions. I have a my65pan butstock on mine. Here is my SBR, it runs great.
They start out looking like this:

And then after a little work they look like this:

When the stock is extended it has the same LOP as a standard A1.

Here is how the barrel was threaded and crowned.

Neat and gorgeous and handy all at the same time.

It shoots very well and I shoot it a lot. I can hit the NRA 300 meter pigs with it offhand. It is the loudest rifle I have ever heard.

Oh, I'll bet it is very loud! I'll bet it is a flame thrower too!

When I was an SP/ Armorer in the AF Reserve ANG in the late 70s, early 80s (after Army active duty), we had GAU5/A/As with 11.5" barrels. Some had moderators, some just had birdcages. The ones with birdcage FH were loud as heck, and had massive fireballs, despite the flash hider. Most of the technicians (full time reservists) who worked full time as SPs liked the 14.5 inch GAU5s, which we also had.

BTW, The ones with just flash hiders, we open the gas port up to .107" (if I recall) because they didn't perform as reliable as the moderators. I think the moderator acted like an expansion chamber on a Krinkov.

I haven't measured the port on mine but it must be pretty good because this rifle runs flawlessly and it really is fun to shoot.

I never did post the a photo of the other side of the XM607 stock which showed this number -
