Convert a carry handle AR-15 upper to a flat top?
Does anyone know if it is possible (and relatively easy with the right equipment) to convert an AR-15 upper with a fixed carry handle to a flat top upper. By this I do not mean swap out the upper for a new one, a mean modify the existing upper by sawing off the carry handle and bolting on a rail. The reason I ask is that on the Strike Back - Season 3 page that is currently being worked on there is a highly customised AR-15 sniper rifle that appears to use an SP-1 upper (no forward assist or brass deflector) complete with the large hole screw pin lower, but it has a flat top:
I am aware of no such upper existing, so was wondering how viable it would be that this was a an SP1 upper that had either had a rail machined directly into it, or had been machined flat and had a rail bolted or pinned on. i am aware of some flat top uppers existing that lack a FA or BD such as the bare bones one made by DPMS, but these look different with a plain rounded ejection port, wheras this upper looks like a regular SP1. If for whatever reason flat top uppers are not widely available in South Africa so they have to make their own, this would also explain the peculiar M4s that have been in all seasons of this show, where the flat top rail is higher than on a real M4. |

Yeah, I noticed that too. It's kinda weird

Flattop AR uppers with no forward assist or brass deflector do exist. Rocky Mountain Arms manufactured those types of receivers for the Patriot Pistol in the 1990s, and I imagine some other manufacturers did as well.
I think I responded to your comments about this on the AR page. Before the M4-style flattop receiver became the industry standard in the late-1990s, the flattop uppers made by AR manufacturers were often very different from each other. I already mentioned the Rocky Mountain Arms style. Olympic Arms also made flattop ARs whose upper receivers had higher RIS than those of an M4 (and their very earliest flattops used the same type of RIS seen on the Colt ACR, rather than Picatinny STD-1913 style). I would imagine that the more likely explanation that the "Strike Back" M4s have such tall flattops is simply that they're from older-model flattop ARs of non-Colt manufacture.

There are quite a few odd guns in this series, but this one takes the cake. Judging from the fact that I can find quite a few matching guns on their website I think the weapons were provided by Hire Arms, and they have a rifle listed as the "M16 PRS Sniper" which is an exact match apart from the fact that it has the standard SP1 upper, which makes me think even more that it is this gun which has had the upper hacked hacked. Just for the hell of it, here are some other odd guns that are listed on there which I think appear in this series and help with the ID:

You are probably right that Hire Arms is the series armorer Commando, so I'll go ahead and make a few changes to the HK33 and HK G3. As for the Accuracy International, I'm going to leave it as is until someone figures out what the base rifle is.

Hire Arms is definitely the armory that supplies this show; pretty much any production filmed in South Africa gets all or at least some of its weapons from them. I actually know one of the armorers at that company. He sent me pictures of the gold-plated AK from "Lord of War" (which appear on the IMFDB page for that movie). I haven't talked to him in almost four years, but I'll shoot him a quick email and ask him about this. If he responds, I'll let you guys know.
Also, I should point out that many of the AR-model rifles seen in "Strike Back" and other South African productions seem to have a smaller brass deflector than a normal AR, which is why I suspect that they're simply made by a different manufacturer.
