Daniel Defense Pivot Pin Hole honed out: Problem or not?

[jpmuscle]

I'm still tempted by the DD M4A1 because it's almost exactly what I'm looking for, a Block II type. The only thing that concerns me now is the castle nut and staking. Moreso the castle nut itself.

Just collect the parts and build up a Colt if that’s the end goal.

I miss the days where JSantoro or Iraqgunz would've swooped into a thread rife with nonsense and locked it right up with a witty remark.

Buy the DD M4A1 and Colt/BCM Castle Nut. Ditch the DD castle, torque and stake yourself and move on. Then we can all go back regularly scheduled programming with less hand wringing....

QFT.

SouthwestAviator, you're wrapped around the axle. It's cool, we can all get there sometimes, but it's time to let go. Buy quality and that will be sufficient -- in fact, ditch the term "perfect" from your lexicon and replace it with "sufficient" and you'll be much happier.

Focus on your proficiency with the rifle and forget the rest. Shit's cool.

This. It’s not difficult or expensive to do. DD is quirky like that in some categories. DD has the castle nut quirk, they used to use huge gas ports (but seemed to have stopped that a few years back). I don’t like the plastic safety selector on the newer rifles but I don’t mind the plastic dust cover. Why anyone would want a plastic safety selector is beyond me. And it’s also lame that DD doesn’t cut the crap and use an industry standard mil spec castle nut with proper staking.

BCM has had issues with their magazine wells not accepting certain Magpul magazine generations.

LMT seems to have had a few out of spec lowers with super tight mag wells.

And Colt has made so many rifles there’s always gonna be something that was missed by QC.

Others have mentioned Sionics and SOLGW. I’ve handled and shot Sionics. Quality and build is on par with the bigger name guys. And Sionics is being used with a lot more police agencies than you’re probably aware of.

I personally own a DD and several Colts. I regularly handle and shoot BCM’s and Sionics. I would not hesitate to own any of those four brands. And I would still buy LMT as well. Bottom line is, as long as there isn’t a serious issue with the unrepairable parts such as an out of spec lower or upper receiver, rail, or barrel; replace and customize what you need to and shoot and move on.

Does this quirk with the castle nut and staking ever lead to any problems with the DD rifles?

[Gtorq21]

DD is a great manufacturer of rifles. I've over thought cosmetic issues myself on rifles. These guns are made to run. I have a ddm4v5. Stop analyzing the cosmetics load some mags and run it like it was made to do. Train with your firearm. If your over thinking cosmetics it's probably sitting in a safe to much.

Nope. You run searches for these questions?

Buy a rifle. Shoot.

[ST911]

If the rifle you want, with the features you want, completes the cycle of operations without stoppage under the firing conditions and schedule you require, drive on.

it definitely might. i remember seeing a couple of posts where castle nuts became loose on dd rifles. do a forum search.

then do a forum search on how dd does not mark their bolts, so technically you really don't know if you're getting a dd bolt or what kind of bolt you are getting at all.

then go see a video from geissele how he talks about barrels (implying DD) not being true hammer forged with the chamber cut by a reamer after the forging process which can lead to accuracy and other issues.

we would all appreciate if you do the research and report your findings and opinions back to this thread. we'd be very interested to learn more on the topic of castle nuts and finish wear.
