ptr91k problem

[reddot45]

sometimes its hard for me to charge my rifle..the cocking lever at times does not unfold crisply it hangs up and can be a bitch to get open..sometimes..any one else have this problem?

[grammaton76]

Yep, I do too. I think it's something that eventually wears in with time, as most of the parts kits I've handled haven't had this problem.

a hk21 style cocking handle makes it alot easier - a guy named
guillebear2000 (?) on hkpro.com makes them for @$65, real HK ones are $165.

If you think the stock trigger is hard to cock back - try a PSG1 - I think Arnold would be hard pressed!!!

It's not so much that the trigger is hard to cock, it's that the cocking lever ITSELF folds up and tends to get 'stuck' quite efficiently. Once you've got it to actually open, cocking the rifle is easy.

Possibly too much clearance between the cocking lever and bolt carrier

[grammaton76]

Are you sure you're talking about the same thing? We're talking about just the lever itself... how the lever (which folds) is really tough to get to unfold - and if you can't unfold it, you can't cock the weapon. This is seperate from a tight bolt pull, and it mystifies me how headspace could have anything to do with it.

Here is what I mean by my post... http://hkpro.com/forum/showthread.ph...n+cocking+tube

It has to do with the cocking tube, charging handle, and carrier.

Both of the PTR rifles I have handled are very hard to unlock. The are currently unfired so I figured as the bolt and rollers start to wear in, it will loosen up. A very used Century rifle I handled was very easy to unlock. I haven't guaged the PTRs yet.

It will break in with time. Check your headspace anyway.

Check the gap between the bolt head and bolt carrier while the rifle is locked on an empty chamber with the trigger pulled. The gap should be between .004" and .018". The closer the gap gets to zero, the harder it will be to pull the cocking handle back because the rollers engage further into the trunnion as that gap decreases. Another area to check, and more likely to be the cause of the problem on your rifle, is the engagement of the cocking handle to the forward end of the cocking tube. As the cocking handle is pulled outward, it cams against that forward end of the tube to unlock the rollers from the trunion. The cocking handle should be able to wiggle slightly before engaging, about 1/8". If it has no wiggle or play in it while in the closed position, it could mean that your cocking tube is mounted too far into the receiver. This causes the bolt carrier to apply pressure on the cocking handle, making it hard to use, and potentially keeping the rollers from engaging fully since the bolt carrier is stopping it's forward travel from hitting the cocking handle rather than from the bolt face hitting the breach end of the barrel. To summarize:
Check the bolt gap, then check for a slight amount of in/out play on the cocking handle and let us know what you find. I don't think I've ever used the word "C**K" so much in one paragraph in my life.....
