CRF vs Push Feed

Push feed was a specified design requirement for the rifles submitted to replace the Lee Enfield as the new Canadian Ranger rifle.


CANADIAN RANGER RIFLE: HUMAN FACTORS REQUIREMENTS VALIDATION

The basic and detailed technical requirements modules collected CR preferences on specific characteristics and features wanted in the new CRR. Results suggest the new CRR should be a manual repeater, short bolt action, push feed design of .308 Winchester / 7.62mm calibre. The new CRR should be shorter and weigh less than the current Lee Enfield. Right and left hand models as well as multiple stock sizes and adjustable pull lengths should be available. Each CRR should include two 10 round box style detachable magazines which the user is capable of loading five rounds in 5-10 seconds while detached. In addition it must be possible to open the bolt, insert a cartridge into the breech, and prepare the rifle to fire without the use of the magazine. Protected iron sights should be the primary sights, with provision for mounting an optical sight using a NATO standard rail or recreational scope mount. The trigger should be double staged, short stroke, with adjustable pull force and a fixed trigger guard. A two position safety system that is operable with gloves, cocking indicator, and trigger lock are necessary. The new CRR should have a stainless steel barrel and a recoil absorbing system (pads). A sling and hard case are necessary ancillary equipment. Further technical requirements are presented and discussed. Due to time constraints during workshops and expertise of CR participants, a smaller sample was achieved for the detailed technical requirements.
Overall, the results from these workshops indicate that the CR require a reliable, durable, and accurate rifle, with updated features that is lighter than the current Lee Enfield. Limitations and future work are discussed.

Given the cost of these things per unit sure doesn't seem like the specified push feed requirement was a cost cutting measure....

Whn it comes to government expenditure, I never even try to compare against civilian price.... We all hear the true horror stories of how manufacturers jack up the price when the govornment gets involved.... $150 hammers and such.....

Will be very interesting to see what price tikka offers the ranger rifle at to civilians.....

Agreed on both points. Government is disgustingly corrupt and abusive and Tikka ... who knows which way that will go.

This is what happens when bureaucrats are tasked with appropriations. The push feed requirement was most likely because push feed was the system that existed on the Lee Enfield, and it was possibly thought that dropping a round on top of the follower and slamming the bolt closed could damage a CRF extractor, or at the very least result in a failure to feed, when neither need be the case. However, a damaged CRF extractor can be exchanged by the shooter, whereas the push feed extractor that is damaged by an overloaded cartridge, or by some other mishap, requires the services of an armorer.

Given the cost of the Canadian Ranger Rifle program, its too bad that a new action couldn't have been designed, one which would adapt to left of right hand use, simply by reversing the position of the bolt handle and reversing the claw extractor on a CRF action, to the opposite side of the bolt, and reversing the position, or exchanging, the bolt head, if a push feed. It would have been better IMHO, if the bolt had been designed to be stripped without tools, something possible with a 98 Mauser, but not a Lee Enfield.

A short butt stock with a spacer system would have resolved the stock length problem. Consider the possibility - a 4 foot tall girl Ranger is issued a rifle of appropriate dimensions, she retires, and her rifle is subsequently passed on to her 6'6" 245 pound knuckle dragging replacement. Wanna bet he doesn't shoot up to his rifle. This is obviously not a CRF/push feed issue, but is typical of a bureaucratic oversight.

The 4 grand isn't just for the rifle. From wiki:

https://en.wikipedia.org/wiki/Canadian_Rangers

The new rifle features a detachable 10-round box magazine, iron sights calibrated from 100–600 meters, a laminated wooden stock, stainless steel construction with extra corrosion resistant coatings, enlarged trigger guards and bolt handles, so they can be used by rangers, without requiring them to remove their gloves. The barrel, bolt and receiver will be made by Colt Canada under licence from SAKO. In addition to the rifle, the the accessories package will include a custom-molded Pelican hard transport case, plus a soft transport case (outfitted with sling, extra magazines, a lock and cleaning kit). Both hard case and soft case and rifle butt stock feature the Canadian Ranger Crest.

Associate Minister of National Defence Julian Fantino announced that the DND planned to buy 6,820 rifles.Including development costs, spare parts, two million rounds of ammunition, the rifles are expected to cost $28 million.
 
With our dollar being down as it is, we could've refurbished a huge pile of M44 Mosin Nagants for the Rangers and they'd have a reliable rifle that can be silently be cocked & de-cocked on a loaded chamber like the LE.;)

What a fun country we live in. Oy Vey!:runaway:

Rangers using Mosin's ... that's a good one.

Put a rabbi's face on that bill and you would be even more on point. Oy Vey! indeed.

Would you pay 4 grand for a Tikka CTR with a pelican case, soft case, sling, cleaning kit a couple, of goodies and 293 rounds of ammo?

they are being made in Canada by colt Canada. With the way people go bonkers over Colt Canada rifles on this forum I am sure there will be people lined up to buy.

The added cost in this licensing/production agreement is likely why the ridiculous price. I'm happy with a stock Tikka CTR myself so count me out
 
Just to introduce a little science to the discussion. Can someone give any real statistics for failures etc. for each action type.

Assuming the actions are suitably accurate the only issue is reliability in real world use. How many FTF per 1000 rounds, how many FTE per thousand etc etc. I would like to see the numbers before I would say one or other is best. In my mind I doubt it makes any difference in a well made rifle. But I do note that the inexpensive rifles are almost all push feed so if indeed there is a difference the quality of firearm also needs to be factored in.

No statistics are available because a rifle that fails to feed or a fails to eject is broken, and in need of repair, regardless of the style of extractor. A rifle that isn't broken works fine.

Now don't be bringing common sense into this Boomer ..

there is one other factor/variable that can cause FTF, FTE and that is user error. I'm sure we have all seen "that guy" at the range who just has no clue and is really his own worst enemy.

If user error is not to blame, then I agree that the firearm is in need of repair because FTF and FTE is unacceptable even once.

Now that's true, and the action has to be cycled like you mean it, not babied like you're scared its going to break.
