Hello all,
Today my new troy Alpha rail arrived in the mail, and I immediately got down to installing it. I finally finished without any real hitches, but when I assembled my rifle and charged the handle, there is a very loud high pitched clink (and it sort of draws out for awhile). Any ways, to be sure that was the sound of my new forend, I grabbed it with my support hand and charged the rifle, and did not hear the sound.
Guys, I know that my rifle is correctly headspaced and what not, and it has always worked fine.
I would think that a very loud and distinctive clinking noise would be a product drawback in one of the many reviews I have read. WHAT IS WRONG WITH IT?? I would really appreciate some input.
^ this. If so did you check to make sure the BCG slid in and out of the gas tube port, try it without CH. Is the new rail allowing the gas tube to align freely out of the upper receiver? Check to see if it’s making abnormal contact. I would be willing to assume your issue is somewhere in the above.
Some tube rails make that sound…sometimes. Sounds like a tuning fork right?
My old 3-gun rifle has a JP tube up front that would make that sound when dropping the bolt/running the charging handle on an empty chamber. It stopped doing it eventually, I have no idea why it stopped though. BCG always ran in and out like butter, tube was perfectly straight in the key.
If you’re experiencing the same thing I did, it’s not the gas tube but simply some weird harmonics.
It may be harmonics like you said thopkins. Maybe. But I still must be sure that it isn’t.
I kind if thought that it might have something to do with the gas tube, but it seems aligned. I’ll do dome more testing on it the next opportunity I can. (Couple days probably)
It is very annoying, because even when I was simply dey firing the weapon, you could hear the clink.
Wait!! But if the free float rail isn’t even touching the gas tube/block assembly, then why would the sound stop when I touch the rail, if it was the tube??
Dang
In order to test gas tube alignment all you need to do is strip the BCG, insert the carrier only into your upper receiver and slowly ride it forward. If it binds or resists then the tube is misaligned.
When I said tube I meant tube rail, I think it’s the same thing you are experiencing. I’d bet money on it. I’d do as IG suggests and check with a carrier without a bolt, make sure everything is tight, and then forget about it. How often will you be firing it or manipulating it that you’re hand isn’t on the rail?
I will check it out when I get home tomorrow, and I sure home I can fix it. I charge with my support hand so it would make a racket every time I charge or press the bolt hold open.
Thanks guys, I will post some feedback when I get a good look at it.
Both of my Troy tube rails (11" & 13") sounded like tuning forks when I installed them. They both stopped after some time, don’t know why but they did.
