Go to the HKPro home page in World of HK. Actually, here it is:Do you have a picture of where on the trigger pack the F/A bolt catches. Thanks
The big reason one that fires from open bolt is less accurate is that you have that large mass (the bolt) flying forward which pulls the alignment off of where you have it aimed. But that really only affect the first shot when on f/a mode.That makes perfect sense now (light bulb moment) It's amazing how all the parts work together. I guess the delay in the hammer coming down would slow the rate of fire (compared to an open bolt gun)
It also goes a long way in explaining why the accuracy of an open bolt gun is so poor compared to an MP5.
(BTW, after watching the video and grabbing my F/A bolt head and Navy trigger pack I see how everything fits together)
Would a handgun be considered pure blowback ?
Na, the hammer doesn't wear that much. And it doesn't need any special care as far as lubrication goes. You wouldn't think of oiling a hammer to drive nails, would you? Since it's hitting parts that are all spring-loaded, it really doesn't take all that much abuse.Also it seems like the hammer takes quite a bit of abuse. Is it a high wear item ?
I would assume it's good practice to keep the hammer pretty lubed up.
And one last question, with an empty chamber, is it good practice to pull the trigger to release the tension on the hammer spring. (I do this on my Glocks as it's supposed to be good for the firing pin spring)
