ANY AR15 GURU'S

[Frankr]

Can a AR15 be made to fire manually ? So as it would not eject a fired case and you would have to charge a new round manually ?
For purposes of testing load accuracy. suppressed loads ect.
Also we here in PA are not allowed to use semi's for Hunting..I thought what if turned the gas system off and I had to charge a round manually maybe I could hunt at night with a decked out AR...Rule book says manually operated firearms only and that would be manually operated..
And it would be cool to have a gas block that could be turned on and off..easily ..one could be easily made..
I also thought I would ask the Game Commission if I used a bob sled and loaded it single shot could I use it..at least that way If I had to I could drop it and stick a mag in..

Actually, Yes. There is a manufacturer doing a conversion set-up that you can go from regular semi auto to swapping out the bolt carrier and has manufactured a bolt that goes in in place and modified the upper to accept this set-up. I have shot these rifles and they perform quiet well. The guy's card is at my business, tomorrow I'll PM you with his info. This mod is approved for hunting in PA. I see you're in southwest PA, both the manufacturer and I are up near Erie. Might be close enough for a road trip. Neat thing also is that it can be swapped back and forth in just a few minutes.

When i had my 300 Blackout upper made up went to Keystone Accuracy Custom Rifles, Plymouth Meeting, PA www.keystoneaccuracy.com they have a billet upper with a chargeind hdl. give them a call

ATF quotes a rule that if and when a weapon is altered, it STAYS altered in their eyes. Some states may mirror that thinking. So if you turn it into a bolt action single you cannot go back to a mag fed semi later. Not sure where I heard this. It was in relation to taking a semi and going full auto and then back. Can't ever go back.

You may be able to close off the gas block and that should stop it from ejecting the case

Closing off the gas block will make it single shot, with something like a Syrac adjustable or Wilson adjustable, but that may be too easily converted back for the local warden to consider a proper conversion. If you did that and put a dowel in the buffer tube so you had to break it open to remove the round, that would constitute a single shot.

Easiest way is use an adjustable gas block. The game warden does make me wonder. I would just get an upper in the caliber you want and not have it drilled for gas.

 

[Fast14riot]

The dowel in the buffer tube is, afaik, a legal single shot conversion. Here in CA, a company was selling ARS in pistol configuration as single shots legally (before the SS exemption went away). Basically, just block the buffer from going back, in addition to a closed gas block. Use an extended rear take down pin with a small lanyard, pull the pin, flip it open and then pull the charge handle to eject.

Hunting season over, pull the dowel and open the gas block and have yourself a semi auto again.

In my thinking if you modify it once you can modify it again as long as neither mod is making it a different classification like full auto or an SBR etc...

Build an upper. Add a barrel without a gas port. Add a side charging carrier group/receiver. Use a Bob's Sled single shot follower, and that may be it. I doubt there is an actual requirement to have a gas system.

It may self eject, if recoil is enough to clear the case, but could not reload due to the single shot follower. You would have to manually reload the next round, and manually manipulate the bolt. You could probably put a heavy buffer spring in to make sure it wouldn't eject, if that were to be a possible issue.

You've got me thinking now. I know where a new blem 24 inch varmint barrel is that has not been drilled for a port..... cheap.....

When in doubt, find a couple of game wardens and ask them, or get a letter from ATF. They may have different ideas on the lower receiver, you could build the whole thing purpose built to be only single shot. I think without a port, they couldn't really call it a true semi, as configured.

Give John S a call at Keystone Accuracy,he is easy to talk to and does great work. At one time there were a few guys building single shot Ar's with side chargers the main reason was so the could shoot different calibers . They would use a 308 barrel extension and bolt on the Ar-15 frame upper.
I know some of the Ar shooters on the other side of the pond have developed an upper that is compliant with there semi ban. It will eject the round and hold the bolt open. You have to push a lever to make the bolt drop and cycle the next round .
Hope that helps
John

I know here in New York That just turning off the gas block would not be enough. Here I am pretty sure changes like that have to be "permanent" before it is actually in compliance with a law.

Or, maybe you could use a 80% lower receiver that does not have a mag well cut out. A few years ago DPMS made a finished lower receiver with no mag well but I don't know if they are still in production. I was fortunate enough to purchase one. I had to modify the bolt release to hold the bolt back once fired so that it automaticlly ejects the spent round. I used a LAR-OPS4 upper receiver with side charging handle. I'm currently looking for a barrel without the gas port for my next AR project...

Couldn't you just use a bob sled instead of a magazine? The gun would eject when fired but would require all rounds to be loaded individually by hand. Maybe that's too easy, but as long as you're not carrying another magazine to change it to semiauto function I'd think it would be ok.

 

[gravelyctry]

My bad, I just retread the original post, and you didn't want it to cycle except manually.

 

[JRS]

Pull the gas block and tube, and replace the gas block with the port mis-aligned.

Edit: Taking your AR in the field to hunt with in PA will most certainly have the Game Wardens checking your gun more often than you'll like.

well yes I been trying to get a hold of the Game commission or local Game Warden to see if I have a bobsled installed and I have to load one at a time if they would be ok with that for night coyote hunting..But I would have a 20 round mag on me in case I needed it for personal defense or to keep from being ate..lol... I can not see why they would not allow it.really I can not fire semi with a bobsled installed...kind of like a plug in a semi shotgun(pluged to three rounds here) I hunted for years with a 1100 that had no plug. I was even checked once and they just checked it only had three rounds.
but thanks for all the info..I will keep trying...

This is how I would do it. I use a side charging upper. Run it like a bolt gun. Fed from a mag is not a problem for me and neither is semi auto though.

With questions for the warden, in the past I have them leave me a voice mail and save it on my phone just I case there is a problem in the field.

 

[Ggmac]

Problems with it not having any primary extraction , it needs a good blow to open a non modified bolt assembly , meaning you just block the gas system .

 

[SaulGoodman]

Being a PA resident, this interests me. There's been talk for a while about the bill going through to allow semi autos for hunting but it has been in limbo for a good while according to their website.
