Hello

Like a handgun rear sight is it a press fit, the dovetail is machined from a special steel that grips the cut in the key. The dovetail makes contact with the screws but not in a manner that would put undue stress on them.

Handgun rear sights do not move if machined correct, some are so hard to move many companies have loosened them up a bit and place a set screw in the middle so you can drift it even then its not easy. We did not put a set screw in because once its there we want it there unless its getting changed completed and also it's a screw that can back out.

We wanted a simple durable fix to this issue that is talked about everyday on the forums. While not all carrier keys fail. The truth is companies use there staking in advertisements and stickys in their forums for a reason; because some do fail or are deemed untrustworthy.

Thanks

True, but there millions out that are not staked to what we all think we know as staked properly. Also true is that staking while a workable idea is a subjective undefined spec.

You'll never convince the Worshippers of the Smashing Chisel.

I like the concept.

I don't like increased parts count or removed material... But this almost seems worth it.

I'd like to know the materials used and finishes applied. I might torture test one in the future.

Any chance of a future hard chromed or NiB'ed version, since that stuff is all the rage?

ETA: D'oh on the last bit, missed the last post.

The torque spec is a big gap that allows many chances to line up we have NEVER had a issue yet. Also most companies torque well past what the spec is, I guess they feel its too light.

Thanks

I have an old Bushmaster carrier that the key came loose on. This is an option to get that thing out of the parts box.

Just a durability question but can the Keyloc be taken off and put back on a multitude of times with out damage done to any of the parts, and the keyloc still work as advertised?

In testing we never found it to move its real tight, that said while it could be taken out a few times after a few it does get looser and I bet if removed many times it may get too loose. We never designed it to be removed over and over. The charging handle does retain it from falling into the action so a QD type is possible but I dont think there is a market for that.

Thanks

interesting concept.

Almost seems like it would make sense to stake the dovetail to insure it doesn't creep out.

This is important to remember because let say someone removed the dovetail many many times which we dont recommend and it therefore became loose just like what can happen on a handgun sight if moved around too much. The charging handle would still retain the dovetail keeping it in the gas key cut out far enough to still engauge the screws. So even in this weird sitution the KEYLOC still keeps your gas flowing and your gun running.

Also to the member asking if someone could stake the dovetail. Of course you could and its much easier, solid and effective to stake/smash a dovetail then stake 2 bolts in 4 places. Staking round parts is a very weak type of staking this is why this problem does not go away. Staking flat angles is much more effective. Also remember staking our screws due to the flats gets you a deeper/better staking, so if your the worlds biggest staking fan this is perfect for you.

BUT I will repeat again this dovetail is so tight it does NOT need staking and while it can be done I would recommend not to just for ease of field replacement in case for example, you drop your bolt carrier and bend the tube interface.


Thanks

See the above posts we addressed this question many times over.

In the very off chance it did become loose, say removing it too much or something the dovetail cannot go anywhere(its retained by the charging handle). If this happened it would chew up a charging handle just like a loose staked key would, but unlike a loose staked key the gas seal is still there, the alignment of the gas tube is still correct(preventing damage) and the rifle will still fire.

A staked key does not provide redundancy while the KEYLOC does.

Thanks
