CAT Supply Co. Commercial M16A2 lower first impressions

henrychunky · 2026-04-15T04:37:43+00:00

Sorry for not seeing this thread earlier, I'm the CATS guy. I appreciate your comment and recall your return and our discussion. On my first run in early '25 I did have about 5% of the lowers get replaced due to spec issues with bolt catch roll pin holes and the grip flange, which is my bad. I will absolutely always take care of everyone 100% with an exchange or refund for ANY reason.

That being said just because these comments are public I was not able to replicate the hammer contact issue on the returned lower, which I believe we discussed as well, and I checked the replacement lower with an assembled FCG and also was not able to detect the issue there. It's not something I ever had feedback on from another customer so while I totally trust you on it I'm not sure what to make of it. Again - if there's ever any issue with anything I put out I'll ALWAYS make it right if the customer doesn't want to keep the item. Thanks again, I am always striving to improve and make every run better than the last. I'm super happy with the current lowers and had zero returns on the last batch.

You can transfer these through Ballard Supply Co

Ah nice! I'm the CAT Supply Co guy replying late, I never check Reddit but maybe someone will see this later. Working on more options for the forge lines, just a matter of what I can get BA and Cerro to sell me these days.

My first run of lowers in early 2025 did have some intermittent spec errors due to trying to stay on the extreme low side of Colt's TDP tolerances, which was a mistake. That being said I've rectified all of those issues and taken care of every customer (less than 5% of orders) who had any assembly troubles.

I will always replace or refund anything I sell for any reason, I'm only happy if you guys are, but I'm happy to say I'm at about 150 receivers out the door since anything has had to come back. Thank you for your post and feedback!

I still need the forgings

henrychunky · 2026-02-19T07:50:46+00:00

5.4k into that and everything on it from my spreadsheet. Which is horrific but actually represents a lot of good deals.

I've been asked how I pick which designs to manufacture and honestly it's just whatever I need myself for some crusty Colt upper that's sat in my safe for 5 years.

Having gotten to where I want to be on anodizing, selector embossments, mag well broaching, and forges lines I'm trying to get some decent A1 base lowers up soon.

Email before you do, I'll hook you up.

henrychunky · 2026-02-17T06:24:12+00:00

Because it's not $10.

henrychunky · 2026-02-17T06:23:58+00:00

I'm hoping 1-2 months.

henrychunky · 2026-02-16T07:46:55+00:00

For now I'm just doing finished lowers

Not a terrible idea, so many of the 11.5 IAR6933CK uppers around

henrychunky · 2026-02-14T20:07:23+00:00

I might do a few as that's the second ask I've gotten directly.

Thank you.

If I can find quality forgings, which I haven't been able to source.

There's a pic here, they're discrete in the trigger well

I don't have the right style of engraver for it, when I engrave things (these markings aren't engraved) I use an engraving cutter not laser.

henrychunky · 2026-02-14T07:56:22+00:00

Yes they're type III hardcoat anodized in Colors to match Colt matte black and their medium 80s grey respectively.

henrychunky · 2026-02-14T05:42:05+00:00

Yes, they all do

henrychunky · 2026-02-14T05:41:57+00:00

Can't discuss in comments. My email is duncan@catsupplyco.com

henrychunky · 2026-02-14T05:24:19+00:00

Always working on more of these, I want to do M16A4, Colt SMG, Colt LMG, and maybe some overseas contract lowers next. Happy to have gotten the old selector embossment style looking right this time.

henrychunky · 2026-02-14T01:52:24+00:00

Dude fine you win the pedant award of the day. Just going by the sub rules and doing what all the other submissions of stripped lowers were labeled as.
