Gwinn Firearms Bushmaster Field Strip (Original Bushmaster Rifle)


– [Voiceover] Hey guys,
it’s Alex C with TFB TV, and for today’s field strip,
we’re going to be taking a look at a Gwinn Firearms Bushmaster rifle. This was actually the original Bushmaster. They made this and a gun called the Arm, which was kind of a
weird swiveling pistol, which you can look up on the Internet if you want to read more
about the Arm pistol. But they basically kind of
both have the same action in they were made by Gwinn Firearms starting in the 70s, designed in the late 70s
and produced into the 80s. It is kind of cool to see
Bushmaster rifle engraved on this before Bushmaster really
made AR-15s and M16s. So, very unique looking gun, if not very ugly at the same time. Very simple. Basically slap sides and the receiver and everything like that,
with a 20-inch barrel. Nothing really out of
the ordinary on this gun. You know, at this point in time, making guns out of aluminum wasn’t new or revolutionary at all. I just think it was basically a low-cost alternative to the M16. But it actually field strips somewhat similarly at the beginning. Remove the rear takedown pin and the upper and lower receiver will separate from one another. At this point, you’re gonna remove the rear sight, which is unusual for sure. I know of no other gun
that actually does this as part of the required
field stripping process. Next up, you’re gonna remove this little retaining clip, and set it aside so you do not lose it. After you have that removed, you can slide the bullet carrier group away from the rear of the receiver. Now, the next step is going to be disassembling the bullet carrier group, and if you’ve disassembled an AR-15, M16, then you should be able
to do this as well. Just go ahead and pop out
your firing pin retaining pin, remove your firing pin from the rear. Go ahead and pop that
cam pin out of there. And then the bolt will
come out of the front. Now of course, you can also remove the extractor from the bolt. So realistically, this part
of the disassembly process is not that much different than an M16s. And this is actually all you have to do to field strip this gun, it being a piston-operated
gun is somewhat simple. It’s a simple gun all in all. It’s not attractive, like I said earlier, but I don’t guess that matters, because they do actually run and they run pretty dang well. They have an M16 fire
control group as well, so I guess in theory you could
pop that trigger group out and put in a fancy trigger. However, I’m not going to
spend any money on this aside from maybe cleaning patches and whatnot every now and then for when I shoot it. I can do a review on
this if you guys want. It’s just such a weird, strange gun that I really don’t
think about a whole lot because an M16, AR-15
is a much better gun, they’re still being made today, and they’re more fun to shoot. But this is kind of an
interesting footnote in firearm history, as it is the predecessor to
the modern Bushmaster Company, and the Arm pistol like I said is also an interesting curiosity. At this point, I’d like
to thank Ventura Munitions for helping us out with our videos, guys. We hope to see you all next time.

  1. i have one its with a wood butt and foward grip. was thinking about changing that but not anymore lol looks bad with that butt.

  2. That Gwinn Firearms Bushmaster Rifle needs to be looked over by Ian so he can do a video on it, that is a cool as hell design and it doesn't even have a Wikipedia article.
