Gary Stevens Posted March 5, 2014 Share Posted March 5, 2014 I have a project in mind that requires a bolt action AR-15. It will be a dedicated suppressed platform in 338 Spectre. This will require an upper receiver that uses an AR barrel and has a lifting bolt, such as a traditional bolt action rifle. I don't want a straight back pull action. Does anyone make such a critter?

ridenrunwv Posted March 5, 2014 Share Posted March 5, 2014 What is the reason for doing the build in this way? The advantage of the 338 Spectre is to cycle and run subsonic loads in a semi automatic platform. If you just want a bolt rifle with AR ergonomics look into a build with a chassis such as the XLR.

Gary Stevens Posted March 5, 2014 Author Share Posted March 5, 2014 Well I have a Spectre that functions as an AR, but I am wanting to eliminate a couple of things. One is suppressor blowback, and two is chasing pretty expensive brass. I looked at the JP bolt action rifle, but would like to find something a bit less pricey. The XLR is a possibility, but I think that uses a 700 receiver and traditional barrel. That would require quiet a bit more expense than what I am looking at. Thanks though.

BradfromND Posted March 5, 2014 Share Posted March 5, 2014 Competition Machine makes a tube chassis. Order a Defiance Mutant action to go with it and never look back. Link to comment Share on other sites More sharing options...
Flatland Shooter Posted March 5, 2014 Share Posted March 5, 2014 If you eliminate the requirement that it not be a "straight pull back action", you could just seal off the gas port in the barrel or gas block. I might just give this a try. Use an adjustable gas block but close it down all the way. Bill Link to comment Share on other sites More sharing options...
Gary Stevens Posted March 5, 2014 Author Share Posted March 5, 2014 (edited) I tried the adjustable gas block, closed it off, and found sort of a strange thing. The back pressure from the suppressor moves the bolt back enough to have blowback. I guess I could use a real heavy recoil spring to help keep the bolt closed, I may need to try that. Another problem with the chassis that uses the 700 action, very cool look by the way, is I can't find anyone who chambers a 338 Spectre in a traditional rifle barrel, and I can't find a 338 reamer to make my own. Thanks for the ideas though. Edited March 5, 2014 by Gary Stevens Link to comment Share on other sites More sharing options...
gunfighteruk Posted March 5, 2014 Share Posted March 5, 2014 Come over to the UK ....................... ALL our centerfire AR's are straightpull/bolt action Link to comment Share on other sites More sharing options...
Gary Stevens Posted March 5, 2014 Author Share Posted March 5, 2014 Yeah, thanks but no thanks. I think I just figured out my idea won't work because of the locking lugs on the bolt. Oh well, back to the drawing board. Link to comment Share on other sites More sharing options...
Caspian_45 Posted March 5, 2014 Share Posted March 5, 2014 Didn't Jake Kempton have a AR made to be a bolt gun? I swear that some one showed up to one of the 3 Gun Nats one year with a bolt AR to use in the manual rifle match. Link to comment Share on other sites More sharing options...
Flatland Shooter Posted March 5, 2014 Share Posted March 5, 2014 Taclite makes some bolt action AR uppers but they are pricey. All appear to be in bigger calibers, like 338 Lapua and 50 BMG. . http://www.tactilite.com/Uppers-50-BMG-416-Barrett-338-Lapua-s/1814.htm Link to comment Share on other sites More sharing options...
Flatland Shooter Posted March 5, 2014 Share Posted March 5, 2014 Come over to the UK ....................... ALL our centerfire AR's are straightpull/bolt action How do they make these non-semi? Remove the gas block or plug the gas tube? I don't know why, but I might do this with one of my uppers. Bill Link to comment Share on other sites More sharing options...
Bryan 45 Posted March 6, 2014 Share Posted March 6, 2014 David Tubb makes a bolt gun AR I believe. But if JP is too much money, I expect a Tubb is even more. Link to comment Share on other sites More sharing options...
dauntedfuture Posted March 6, 2014 Share Posted March 6, 2014 If you close off a gas block you still will get a little gas through. You could just move the block firearms and cover the port and remove gas tube. There are outfits that have bolts handkes machined into the right side of the bcg and appropriate uppers with slots cut in. If you went this route you would have a straight pull action. You could cut could off buffer spring but you still gave to have enough to strip rounds out of Mags. I suppose you could make more if a traditional bolt action with a 1/6 throw but why? Go straight pull route and Block gas or bolt action; you can find a reamer if you look or the sane places that make .338 whatever ar barrels could do a 700 barrel.

dauntedfuture Posted March 6, 2014 Share Posted March 6, 2014 I would just buy a brass catcher for the functioning semi auto and a gas buster ch. just saying. Link to comment Share on other sites More sharing options...
HRider Posted March 6, 2014 Share Posted March 6, 2014 You can cut off a gas tube and turn it upside down in the gas block to block off any gas. That, coupled with a side charger upper would make a pretty fast MOR. Hurley Link to comment Share on other sites More sharing options...
gunfighteruk Posted March 10, 2014 Share Posted March 10, 2014 British one's have no gas tube hole in upper or barrel ( made just for UK market) all other parts are the same. watch the youtube: Link to comment Share on other sites More sharing options...

TRUBL Posted March 25, 2014 Share Posted March 25, 2014 Jake drilled and tapped the top of the receiver for spring loaded detent pin. USPSA, at the time (and still may) Outlawed a 'spring assist' to return the bolt into battery. I believe that the detent interfaced with the gas key, that had divot ground into the top of it.....to keep the bolt carrier in place during firing. There was no gas hole in the barrel. The bolt is not coming out of battery unless you pulled bolt handle straight back. Then he drilled he fashion a bolt handle attached it to the bolt carrier and further cleared the upper for clearance of the bolt handle....just like our friends across the pond are doing. Yeah....Jakes a smart guy alright Very easy to jack a spent round out and beat the USPSA law on spring assist into battery. Tim Link to comment Share on other sites More sharing options...
