First Strike Automag

[El Camino]

Hello, I'm posting this build thread because a few members have asked about the First Strike Mag, so here it is,
As you see, not much work has been done to the marker, really, most was done on the body. I cut the feedneck off and milled the hole in a "D" shape to match the First Strike paint (and to fit my finger in there). It's a closed breech, single shot. Slide the barrel/adapter forward then you drop the First Strike paint (or regular paint) in the end of the barrel adapter, then slide it back. The adapter, when pulled back, sides over the nose of the bolt about a 1/6". It's a cocker threaded barrel. What you see in this pic, is the adapters I had made, cocker threads on one end and .690 bore on the other. The hole on the side is for a Spyder nipple detent. The hole for the 10-32 bolt to slide the barrel/adapter forward and backward, was not drilled till I installed it in the body so it would line up for when I milled the slot. Right now it's shooting at 334 FPS and it's VERY QUIET!! and I do mean VERY QUIET!! That's about it, there was more time spent figuring out everything so that I got it right the first time. My biggest expense was having the adapters made at a machine shop, while I milled the body. Oh, and the sight rail I milled down and mounted a Picatinny rail on it so I can use it like it is or add a scope, red dot, laser, etc.
Thanks for looking!!

Nice work!
Now you need to come up with a first strike magazine and mount that to the body

how easy is it to grab onto that bolt to slide the breech open/close? looks like you could use something beefier to hook your finger onto.

other than that, looks awesome

My thoughts are that he just grabs the barrel itself to move the system... Could be very wrong though.

Nice work!

I'm working on 10 to 15 round mag now, a lot more work to make one to the shape of the FS paint. I would love to have one made of carbon fiber.
The drag pressure for sliding the breech open/close is controlled by an o-ring sandwiched between the barrel and the adapter, the tighter you tighten the barrel and adapter the more the o-ring squeezes out, the tighter the drag. The bolt in the side of the adapter sits out about 1/2", which was plenty to get my thumb and finger on to slide the breech open. I wanted something a little fancier and I was even working on something but the bolt worked great and cheaper.

I sit corrected...

Not sure if I missed something but why did it need to be a close breech? Couldn't you have just opened up the feed hole and dropped a FS round in there?

Nice work though.

My guesses are: Safety and reliability.

No need for a LX on this type of mag.

Very nice. Seems a bit overkill though to have an XValve and Intelliframe on a single shot breachloader.

Well, that's where I started with the prototype. What I found was it was hard to get the paint in and lined up, with round paint it is set to go do to it's shape, but with FS paint it has to be in the right position. If you have the paint sitting with the hole beside it and it moved, which it does because it's nose heavy, then it would break when you shoot. If you push it in the barrel a little bit, then you have to keep the marker pointed down or the paint would slide back out and not sitting right, and then would break. So with a close breech, you open, drop the paint in (marker pointed downward), close it, the paint now sits up against the nose of the bolt, sitting where it needs to be and it will stay there till your ready to shoot.

The X-valve w/LV10 was what I had, a Classic valve would work just as good, just be sure you have a tuned LV10 on it. Don't forget your finger is in there sometimes. The Intelliframe I had laying around when I started the build. I love the single trigger frame a lot better, but my single trigger AGD Intelliframe is not done yet, almost, but not yet!

The prototype was a pushmepullme barrel system!

If you can figure out a magazine for the rounds, and then put a pump handle on the barrel, I would be all over that. As it is, it is still very very awesome.

Because of the shape of the round the magazine will have to go straight out the side of the body to work, so it won't have but maybe 10 to 15 rounds. But still better then a single shot.

Pump? It would work if it was a mag-feed.

Good thinking. I am glad that you are more thorough in your thinking than I am

Looks great , the big question is how many adapters did you have made ?? ( I need one of these )
