The advantages of a feed ramp regarding
a .22 rim fire breech face

There have been many different .22 lr conversion units that have been developed over the decades for the AR-15.  Some have an integrated feed ramp on the breech face, and some do not.  One of the oldest and most abundant in the last 50 years was the Army M261 M16 conversion unit.  This unit functioned well enough to train the troops, but did encounter quite a few jams regardless of ammo used due to the inherent nature of it's design using a flat breech face, causing quite a few of the soft lead projectiles to get stuck on the sharp chamber, resulting in a malfunction.

Other units have made functional developments, but I choose to use the Stag Arms / CMMG stainless steel conversion unit for all dedicated .22 uppers that come out of my shop.  The production of a barrel is a bit more costly due to the extra steps, but the cost is easily justified for the following reasons:
They utilize and integrated feed ramp in the unit, which gets duplicated in a 1:16 twist Green Mountain rim fire barrel (as seen above).  They are stainless steel, which makes for a virtually corrosion free surface.  They run extremely well even in a full auto application.  They are also produced in both right and left handed configuration for all to enjoy.
The above picture illustrates a barrel that is being milled to accept the bolt of a Stag left handed conversion unit.
A .22 LR match grade upper is quite a bit different than a standard center fire match upper.  A standard match grade AR barrel is contoured, threaded to accept a screw on barrel extension, chambered, and crowned.  A .22 barrel must use a .22 conversion kit as seen here.  They are offered in both right and left handed versions.  They use a blow back operated bolt that slides on a rail and a .22 rim fire chamber adapter that fits into a standard .223 or 5.56 NATO chamber.

In the case of a match grade .22 LR upper, the chamber adapter is disposed of and the breech end of a 1:16" twist rim fire barrel is machined to accept the existing parts of the conversion unit.  There are many steps that go into the production of this barrel due to the geometry of the working pieces.

.22 LR single round Bobsled
This single round load device was designed by Keystone Accuracy specifically for the Stag/CMMG .22 conversion unit.  Shortly after, I contacted Bob at the Original Bobsled to put into production.  The result is a working single round load device that holds the bolt open after each singly fired shot.  It functions with both the right and left handed conversion units.  They are available in the standard service rifle or a shorter version for the match rifle.
