Straight Pull AR for stalking?

[JohnCZ]

Feasible however -
Life is just too short to hunt with ugly rifles and an AR is the last girl at the bar at 3am.
Just too fat, short overall mag lengths, over priced poo-sticks.
Stalking with and AR =

There will be residual pressure in the barrel during unlocking as the gas is bled off for the BCG before the muzzle.
The gas take off is positioned so residual aids extraction instead of solely relying on the BCG and it's tiny extractor acting on a tiny brass rim.

You can believe what you want, but in the AR system (or probly any high pressure centerfire semi/full auto) there is no residual pressure when the bolt unlocks. Yes there might be PSI or two, based on gas inertia and exit pattern in the barrel, but nothing to speak of or aid in extraction. If there was, it would not help but hinder the unlocking and extraction. In addition to shoving all the lubrication and crud inside the action back at your face and/or mag / any other escape route.

Some ill designed firearms, like blowback 9mm AR (depending on barrel length, bolt/carrier/buffer mass and ammunition) can bleed some of the gas from chamber end but that's the gas inertia at work. And properly designed blowback rifle/ammo system won't do it. You can directly see from brass whether it's clean or sooted. Same for non-flowthrough moderators on AR, the brass will get sooted but it's the gas trapped by mod and no pressure to speak off.

I think you just contradicted yourself there.
How have you determined the amount of chamber pressure at 1 or 2 psi?

What’s the feasibility of using straight pull AR type rifle for stalking, specifically in 6.5CM (custom build of some sort)

Perfectly feasible. As long as you're happy to be treated as a pariah

He broke the UK law then? On his visitors cert application, perhaps he did not mention that it was a semi auto and the FEO was non the wiser. All's well that ends well.
I am sure he meant no offence officer.

His Visitor Permit had the details of the rifle and it was inspected at the airport, he was told all good.

Semi-auto centre fire rifles were popular for general hunting use down here, up until about 6 years or so ago when they got canned.Now only persons with a license to cull animals professionally can use them....hopefully that will change somewhat in the future.Straight pull AR type rifles seem to sell in reasonable numbers now for recreational use and they are used for hunting Deer,goats,wallabies etc quite successfully.However most have stuck with conventional bolt-action rifles, especially the Tikka t3 they are ubiquitous.But I personally think straight pull rifles, as long as they operate reliably and smoothly, would be a good choice for hunting use.

Biggest challenge you have is that vast majority of straight pull, AR based rifles are 223. Last time I looked, 223 are only legal for use on small deer ( roe, muntjac and Cwd depending on which of the Scottish border you are).

There are a few straight pull conversions of 7.62 semi’s - mostly the old SLRs. Fine for range use with open sights. There will be straight pull conversions of AR10 platforms.

Cost. Most of these straight pulls are expensive, especially compared to good bolt action rifle.

of course you will also have the advantage of a bayonet if you use a SLR straight pull

Full semi auto AR-15 on beaver hunt

 

[purdeydog]

If it’s legal then no issue. However it seems a bit Walter Mitty weird and if I’m honest would hesitate to go stalking with you. Each to their own however.

If you share eastern border with Russia, AR in the gun safe is quite normal. Not the best for beaver, however every rifle must get some field use.

Similar story up here. i have a guy in my club who has some kind of SIG in 5.56 and stockpiles ammo and canned food in little compounds around the area. Bit of a weird one, loner, keeps to himself. Brings the rifle to roe deer hunts with great results.

Personally, I don't like mil-tech triggers on my AR, and I find it hard to justify spending 300+ EUR on something like the Geissele SSA-E.
