Gas Block Problem

[Waywardson174]

Picked up a Troy low profile gas block to put a long free float on. Put on the gas block and the rifle wont cycle. When I put on the old DPMS gas block, it cycles just fine.

The only functional difference I notice is that the Troy low pro gas tube hole is drilled all the way through the block. I notice there is some discharge forward from the gas block. Am I losing too much pressure through this front outlet to cycle? What is the solution?

I don't think the hole should all the way through... Lemme look at mine.

Mine doesn't have the hole all the way through, the one that I have is troy low profile gas block

Is it possibly mounted bassackwards and blocking the port? Was recoil more substantial with the Troy?

This was my first thought. Checked and re-checked. It's on right. No noticeable recoil difference.

This is the picture of the block from Troy, seems like they designed it with the hole all the way through.

The link you put up shows an oversized gas block. Is this the right size for you barrel? Just something I noticed. Good luck getting your rifle going.

I use that exact same block on one of my uppers. No issues.

Make sure the gas port is lined up correctly.

Used plenty of similar ones. The hole all the way through is fine, that end of the gas tube is sealed. You will get some gas forward on the micro gas blocks(low profile, and short length blocks). Not enough to really tell until your go to clean off the outside of the barrel and get a little residue on the patch.

Make sure it's lined up. Pull it apart and stick a small punch through the barrel and block to make sure the holes are unobstructed.

did you put on a new gas tube or use the old one. how old is the rifle. the new block could have pushed old carbon and gunked up the system somewhere. its either blocked somewhere or leaking.

What ever happened to this problem? Did the problem get found and fixed???
