BNM Bolt Probe Problems?

[ACZan]

I had a stock bolt, so loose that it somehow unlocked and blew the bolt backwards and open.  Scared the tar out of me.  Felt the blast of air on my face, was fortunately wearing eye protection.  Luckily the pellet went forward and believe it got stuck in the barrel with all the energy escaping out of the breech.  In the case of these breeches, Roy at Mountain Air did notice my bolt was a bit loose.  Combine the two problems and you'll have the one instance where something will exit out of the breech backwards, parts of pellets, parts of magazines.  There is a Murphy''s Law.  Murphy's Law was demonstrated on an occasional if not regular basis on the Myth Busters.

I have over a couple decades experience and licensed in handling explosives.  You don't take chances with something like this.  It is a potential safety issue.  As an owner of a company I wouldn't take the risk of litigation putting out a product with projectile blocking the port.  It would have to be a recall and possibly one that would close a company's doors.

Speaking of things like that, I still have to check to see I if I have those defective airbags in my vehicle.

Chris , A large number of safety issues are caused not by defective design but rather cockpit error . As hobbyists several basic things are required First and foremost is what dangers exist within the scope of what you are working with. HPA like explosives can be dangerous. Whenever I work on my AG's safety is always front and center. Before I even touch the AG . I will spend  several hours doing research. Then ask questions. I never assume that I know all the answers. the last thing I do after reassembly is check my work to insure that all the pieces are back in the gun and all fasteners are tightened to spec and secure . That is how you get to become proficient at what you do. As you know being an explosives expert. At this point first and foremost is that it is not a powder burner where incorrect head space  of the bolt can create an explosive failure. That is not what has been described here but rather the bolt fails to insert the pellet fully into the breech to the point that the pellet is past the transfer port. That being the case the problem is not a safety issue but rather a performance issue causing the pellet to leave the barrel at a slower velocity than expected.

Lets allow the vendor time to sort out the problem rather than speculate on things that may not be a problem and ascribe non existent dangers

Sfttailrdr46,

The rifle to which I am referring is a an unmodified out of the box rifle, if you are implying operator error.  Too much room for chances on a defect, ones I wouldn't take.  I have see what happens when projectiles fail to take their intended path with high energy forces behind them.

No I Imply nothing what I said and will say again is that if the bolt was installed properly and the pellet does not insert slightly forward of the transfer port the greatest risk is poor velocity as long as the bolt is locked in place the full charge of air released from the valve will not propel the pellet to the proper velocity since some of the air will most likely blow back through the breech seal not propel the bolt out of the back of the breech

I intentionally block the barrel port with an adjustable bolt retraction all the time.... If the breech is built properly, there is NO safety issue.... Having the bolt pop open on firing is a completely separate issue to pellet position....

Thank You Bob for chiming in your expertise is appreciated

The statement was addressing the possibility of several things failing at the same time.  It happens you know.  You missed the point.

What is the propose of intentionally blocking the port and preventing the HPA from taking its intended path?

[Mudbugmitch]

Yep, you got my attention. I had planned on leaving this alone, but Mr. soft tail had to pull my string, so here goes.
Which one of you three have a dog in this fight ? Hmmm? Right. Make your opinions, post them, and get patted on the back by your fellow wall flowers. If I say anything I get warned of Bashing. You guys are the experts ? You didn't make the breech that I bought, or did you ? Why not send all of your saged advice to "the unnamed company". Maybe, he will get back to you.
Is a partial blocked transfer port  NOT a POTENTIAL safety issue ? I think "maybe". That may not be your opinion and I am OK with that. But I won't be taking that chance.
I ask for a replacement breech, that is all.
 I have stated the facts of my case. I thought that this thread is where we were to discuss this issue.
You "experts " seem to be siding with the " other guy", where is the GTA membership loyalty ? What rule is that covered under ?

Mr Sfttail agreed that you had stated that you were going to allow things to sort themselves out and I said that was a wise decision I did not suggest anything more than that . I was not attacking you but you need to understand that it is my responsibility to insure that all members abide by the rules that we all as members agree to. If we cannot all do that then the forum will become a free for all and we are all here to share our passion for air guns. If there is a safety issue then by all means present it as clearly as possible

 If there is an issue with a product or the vendor that provided it then it is acceptable to present that problem on the buyers and sellers gate.

Stick to the facts and there is no problem.

 I am responsible to monitor this gate and and insure that all posters abide by the rules. If any member feels that they are being treated unfairly by me feel free to advise administration that I am being unfair or unreasonable I will be more than happy to allow that member to try doing this job in place of me.

At this point if you feel that there is an issue with the BNM Bolt probe use the Buyers & Sellers Gate feel free to repost  the thread explaining the issues and what has transpired with the vendor

Just remember to explain in detail "Without Bashing" what the issues are

Now consider this thread locked

[Rocker1]

What bad is their is some useful information in this thread  and you sir I never accused you of anything  but truth is the thread should have been killed days ago for this I take the blame. Now it will stay locked until I get the chance to remove the bs from it. David

Jay, we are not supposed to bash people or companies on the GTA.... Making people aware of a problem is one thing, but I would be careful with your comments or the Mods will be all over you.... JMO....

                                 I understand Bob but this Gentleman's Company {BNM Custom} IS Not A Forum Sponsor! 

This forum has NO sponsors. But does have rules against bashing anyone.
