The Timing Could Not Be Better !

[call2arms]

Well, now that you mention it, some of them are machined and some are cast. Don't ask me why they switched but there are a mix of the two on these rifles just depends on which one you have.

Sounds like a norinco m14/305 bolt

[$kull]

How can someone like myself, with little to no knowledge and experience with machining and casting, know the difference with my gas block? Are there some marks that would give a person a clue? I have a few of those tiny circle indents on my gas block like the ones I see on your picture that are next to the latch detent spot.

Cast will usually have supports, like the two lines on the curve in the ones pictured and machined ones won’t have swooping curves etc and be more square and have a better “luster” in sheen

Usually
Not always with cast vs machined and machined castings make that even worse
But that’s my experience
I’m not a machinist nor a doctor

Thanks for sharing that, super helpful. I took a closer look at mine and crap, mine is definitely a factory cast gas block.

Mine appears cast as well. Not ideal, but doesn't necessarily mean it will fail either. Hopefully Dlask keeps some extra gas blocks around for future repairs.

Mine was an 11" 5.56 but has been converted to nr, so no factory warranty for me. How much for just a gas block?

We only ordered these in sets and will sell them in sets with gas block + trunnion, sorry.

Understood, thanks for the info!

Tks for the great info! So out of the five that have gone through my hands, only my 16" (SN: G3XXXXX) has a machined gas block, all the other four (all are SN: G1XXXXX) have casted gas block...

[Skweezbox]

Damn. The parts are in stock but not the install. Did I miss out?

[Bfranklin]

Lol.

How many people swore up and down that the Bren2 was better than the APC.

Anyway, cool to see Canadian manufacturing getting it done.

Well to be fair, this is the only issue so far that has popped up so that's not bad at all. As with all new firearms they will modify the future parts and beef the blocks up or just go with machined billet instead of cast. The B+T GHM9 got modified into THREE entire Gens in only two years iirc so like I said, not unheard of even for the best of companies.
