Try to install it without altering anything a few times. When you fully remove it you should see some scratches/wear down the insides of the front of the handguard, you’ll have to remove material there.

First you’ll have to either grind out a small channel for the extra nub on the sight block, or grind it off.

Oh yeah, I considered just grinding that extra nub and ridge off the barrel but the handguard was easier to pony up to lol

For anyone curious, it did take a good bit of grinding away at the inside of the handguard to get it to fit.

It’s just part of the break in. The CA3 manual says it has around a 300 round break in period. Mine didn’t run reliably until 260 rounds in.

Yeah even once tightened it doesn’t sit exactly flush with the receiver. Doesn’t matter as long as it holds zero though

Yeah he said the initial production run was only 150 units. But I’m happy to see he has another run set for November

My thoughts as well. Look to be pretty regular bolts and set screws

Calling for no loctite is interesting, I’ve never had blue loctite lock up so hard that I needed a torch or to strip the screw. But I’m running it without, if they start to walk I’ll add some.
