No one is currently making true A1 uppers or lowers. You can look for a Sendra on the used market (that's what I've got), which were forged and A1 spec. I think some of the EA receivers were A1's as well. The uppers are available as M16A1 take-offs, also on the used market. I have heard a rumor that Fulton Armory may be producing new A1 uppers soon, but don't know if this is true or not.

Fulton sells m16a1 and M16 style uppers (with and without out the FA), as well as a lot of other sellers. What makes these untrue uppers?
Every lower for sale new manuf has been A2, which is a stronger lower than either m16a1 or M16. |

I have two Fulton uppers, one is an M16 slick side and the other is a late M16A1 style that has the case deflector (aka 'Brunton Bump') that some refer to as the M16A1M upper. I've yet to see a Fulton A1 style that has the FA but not the deflector. I'd like to see them offer one.
BTW - the Fulton uppers (and their lowers for that matter) are first-class all the way! |

Early PWA lowers were A1 configuration as well.

Early Eagle Arms lowers (pre-Armalite) are also A1 configuration. They were reportedly made by LMT.

The Fulton upper with A1 sights, forward assist, and case deflector is actually a Canadian C7 style upper. It's not a true M16A1 upper.

On page three of the attached thread, the guy from Fulton Armory is talking about them making a true A1 upper, with the FA but without the shell deflector. Maybe if everyone starts calling...

How difficult is it to come accross these A1 receivers? I'm assuming that it's something of an ordeal, given the apparent scarsity of manufacturers that produced A1 lowers and the surpluss nature of the uppers. At any rate, how much would one of these bad boys reasonably set one back?

No, Delta-9 I had not seen that thread. I read the first page, and didn't see what I was looking for (no forward assist, no A1 lower).
Thanks, though. |

Can one of you gurus set me straight here?
A true A1 rifle would have a "smooth" sided lower, an upper with no FA, A1 style rear sight, the stock would be about an inch shorter, triangular hand guards and a 3 pronged FH. Am I even close? Thanks |

No. The single defining feature of the A1 model was the forward assist, though many other upgrades were also eventually a part of the A1 spec. Due to the (Vietnam) war and the quick adoption of the M16 family in the midst of the buildup, new features weren't added all at once, but were added as they became available, so there were a lot of guns with only some A1 features. One of the biggest misconceptions is the slab-side lower. All A1s had fenced lowers, as shown in Beowulf's pic, without the A2 reinforcements. Most of the XM16E1s had the same lower as well. Only the earliest M16s (almost all Air Force rifles) had slabside lowers. The confusion comes from the fact that Colt had piles of unmachined, raw slab-side receiver forgings sitting around, but updated M16 specs prevented them from being used for military rifles, so Colt used those raw forgings to manufacture the civilian Colt SP-1 and later rifles, until they finally ran out many years later. When those raw forgings were finally depleted in the mid-80s, Colt went directly to A2 forgings, bypassing the A1 lower entirely for civilian guns. The point is: you have to be careful not to confuse Colt's military and civilian offerings which rarely matched each other feature-for-feature. -Troy |

Well, after having just checked Fulton Armory's webpage, I see neither A1 uppers or lowers, just pre-A1 slickside receiver parts... I wonder if I ought to email or call them up to see if they're actually going to offer A1 parts in the relatively near future.

I guess we could call the slab side the "A0" for the M16 and the A1 would be for the M16A1.
Gets confusing with all the "A1" talk. |

I don't think some people really know the difference between M16 "slickside" uppers, true A1 uppers or A1 late model uppers. Here is the scoop...
M16 Original production as seen from 1963-1967. Also typifies Colt commerical SP1 production. This unit is from a military M16  A1 Introduced in 1967 this version featured the forward assist that was introduced on the Army's XM-16E1 and carried forward officially into the A1 series. Other minor improvements made. Two versions are pictured below The upper version features the A1 sight and forward assist, as found on a 6550. The lower image is a late model that also featured the case delfector.   |

The "late model A1" is really a Canadian C7 upper. When Canada adopted the AR/M16, their standard version was a 20" rifle with an A2 barrel, but otherwise mostly A1 features. But they added the brass deflector to the A1 upper for the first time, hence it's a C7 upper. Colt now uses these Canadian C7 uppers whenever someone wants an "A1" upper on a modern rifle.

You can get them; all Colt SP1 and Sporter lowers are just like that (though they have a large-hole pivot screw).

Hey Troy - my light weight sporter has a small hole pivot screw. I removed it and installed a push pin. Do I misunderstand you or do I have something rare? Purchased the day the ban passed in '94. |

During that time frame any would possible. as every AR manuf was trying to get as many out the door as possible.
One think Colt makes it had to do is track when they made changes. |

Sorry, but the SP1 lower is NOT a dup, by any stretch of the imagination, to an A1, or even an "A0" lower. It's totally w/o any hump, for either the hinge pin spring/detent, or mag catch protector.
The early Sendras are about the closest one can get to a semi auto A1 type lower. I'm just finishing up the metal work on a Rock River lower, "A1ing" it. Since I don't own a milling machine or lathe, I've been doing it by hand, and it's been a real PITA  When I get the refinishing done, I'll post some pics.Was going to do an M16 type also, w/o the mag catch fence, but after the amount of time and energy I've spent on the A1 job, think I'll bite the bullet and try to find an old time original lower.

SNS Industries will be making quasi slabside lowers like the ones used on the early XM and CAR series, with a 'fence' for the pivot pin retaining spring and no mag fence - however, it will be black and have the A2 front and rear reinforcements.

Aren't some of the older SGW "stop sign" lowers also of the A1 configuration?

That is close, don't look bad at all. But no, the M16A1 did not have a lower like that. The M16A1 had a mag fence. Lowers similar to that were used on Colt's Model 02/602/AR-15/M16, and early Model 603 (read XM16E1). |
