I recently purchased my first AR and my first Ruger. After purchasing a QD sling mount, I discovered that either gas block is too thick, or the channel that was cut for the sling mount bearings isnt in spec. Has anyone encountered the same issue? Do I need to file the block to the correct spec? I asked a local gun store to try connecting a sling mount to another Ruger AR 556 and one of the two he had in stock has the same
problem.

What type sling mount button/buttons does it have ? Push in with button on the end or pull 2 side tabs down while pushing the QD swivel in. Can you add a picture of it?

Its push button.

This type swivel ? It has a button on each side.

When you push the button, and push the swivel in the hole at the same time, it doesn't push in ?

Yes, it has a snug fit, however the bearings will not lock into place. The mount will pull out every-time.

I bet the swivel post is to long. Mine is a Magpul swivel, stupid thing was $27.00 I almost fell over, but it fits perfect.

I dont think the post is too long since the end of the post is not hitting the end of the hole. I havent measured it yet, but I believe the channel was cut too deep inside the gas block.

I hate those push button swivel mounts (QD). Too easy to bump and pop open. I prefer the post type that actually lock with a pin inserted through a hole and the pin has a lock on the opposite side. Most don't swivel, but I've never had any issues with them just popping open.

Before messing around with your front sight tower sling swivel socket I would try a different sling swivel. I have not had any trouble getting a couple of different brands of sling swivels to work on my AR556 but I have seen multiple reports of sling swivels that have either fit to loose or too tight in various brands of ARs while a different brand worked fine. It may be that the sling swivel you bought is simply out of spec.

I agree. It's a "get what you pay for" and there's a TON of cheap junk knockoffs (made for airsoft) out there being sold "as the real deal". Best to spend a little extra for a known name brand that will back their product and replace the problem, no questions asked.

Thanks thats solid advice. The current swivel I’m having trouble with is made by 5.11 I will try one made by Ruger or the one me mentioned with the pin. I might also try filling the swivels itself rather than the block to get a fit.

Magpul products have me spoiled. They're a bit pricey, but are quality built, reliable. and I can live with it. They've earned my loyalty over the years.
