The Stag 10s NR stripped receiver set thread

so I'm noticing that some of my mags will not push the bolt catch enough to lock the bolt back when i drop the mag.

what are the top choices for replacements these days?
I'm a "noob" to these rifles for lack of a better word so not sure if it's a follower issue or if a higher quality part is in order. If I push on the catch it will hold the bolt every time but like i say, some of my mags don't activate it enough.

Which mags are you using? If it's the XCR-M 10 round mags, some of them are slightly off. Look in the BCL threads and you will see some of them require adjusting to spec. I have 5 of those mags and in my DPMS GII recon only 3 will lock back properly. Also avoid the DPMS mags. They are complete crap. The DPMS mag that came with the GII, didn't even work in the GII. Fortunately I have a gen 1 DPMS and it works ok in that. I've found DPMS mags to vary a lot per mag.

Pmags are your least expensive and decent reliable mags. KAC are also good but about $150 each. :(

There are a few others out there as well. If D&H mags a 308 mag it might be worth looking at. Their 223 mags are my goto mag and work in every rifle that I have which uses the Stanag mag system in 223/5.56.
 
it's only happening with one of my 5/10 lr/sr pmags and a couple of my 5/20 lr/sr pmags. The XCR-M mags seem fine.
I'll keep reading up on these rifles and parts and stuff . It will be a few months before mine sees any live fire anyways.
I wonder though if the bolt release spring is a wee bit too strong but I'll monkey with that idea when i have some spare parts to test that theory with.
When I manually cycle the bolt with an empty mag, it will hold the bolt open everytime. It's only with a few mags that the bolt slams to battery when the mag release is pressed , indicating those mags aren't actuating the bolt stop enough...... does that make sense?

seems like a minor issue , the part certainly isn't bottoming out or contacting the upper or anything like that and does work with all my xcr-m and other pmags.

It could be a number of things.

1) The mag. Spring is slightly weak, follower isn't to spec etc.
2) bolt catch, bolt etc needs to be oiled/worked in
3) Your buffer tube protrudes too far into the lower causing the bolt not to go back far enough (doesn't seem to be the case though as you said you can manually hold open the bolt)
4) Your buffer tube is having a slight issue and not allowing the bolt to go as far back as needed (I've had this happen. PWS buffer tube and had to go back to the factory one).
5) Wrong spring. You used a BCL spring etc and it's a longer Armalite carbine spring than the shorter DPMS one. Or the spring you're using is too strong. I doubt either one of these are the reason but have to list as possible causes.

thanx for the input, appreciate it ;)
I'm not gonna fuss too much about it until the rifle is built and on the firing line.
So far I just have the heart of the gun assembled , upper/lower/lpk/bcg/carbine buffer assembly and charging handle. All the parts are Stag-10 components. scope mount, Handguard, gas tube and block will here tomorrow. Will be waiting a bit for the jury barrel so might grab a faxon or BA barrel in .308 to tide me over if any come in stock before then.

It may also be how the mags are pinned. While the rivet is the most common, depending on where the spring sits inside relative to the protrusion of the rivet, the spring may be binding, thus causing what would appear to be a weaker spring.

good one man..... I will check that, thankyou.

Good point and would fit with the symptoms.
 
I just received my Stag 10 upper/lower along with BCG, buffer, buffer spring and charging handle.

This is a quality product. The upper/lower comes with lower parts kit installed, including an enhanced aluminum trigger guard and hogue grip. I changed out the grip as I prefer the ergo, but the hogue isn't bad. Plus the lower had a nice hex screw for the pistol grip rather than some of the cheap stuff I've seen with other companies. BCG looked very good. I took it apart and oiled it. Everything looks like quality.

I did have an issue though trying to use a PWS enhanced buffer tube (It's a gen 1 ie no castle nut). It just didn't sit right in the Stag. I tried two different PWS enhanced buffer tubes and the same problem with both. So I had an older unknown brand buffer tube sitting around and used that. Went on perfectly. Looks great.

Just waiting for the barrel assembly. Should be here any day.

I checked my magwell and the mag catch is correct. It's flush with the catch being the only part sticking out. I tested it with gen 3 pmags, ACS 10 round pistol mags and KAC. Worked properly. Mags drop free as well.

I've added a badger ordnance gen 1 tac latch to the Stag 10 charging handle. Didn't feel like going with a Raptor when this rifle isn't ambi.

Im happy i got every thing and somewhat put together and it looks good but my handguard is something like 6mil too long :( so im going to cut the HG and hold it together with wire and electric tape and go with a falloutish look or plug and drill the gas port.

is that an armalite handguard?
might be why it's to long. Thought i read somewhere that the ports were in different locations for dpms vs armalite but maybe i'm confusing that with something else. 6mm seems excessive.
gonna look cool and retro-ish when your done
are you going to get a carry handle unit as well?

Iv bought a DD A1.5 rear sight and I'm looking for a c79 later on. Its a C7.62 :)
 
They are from a c7a2 and was told that they should fit. I'm down but not out.

It sounds like you were told they would fit based on the predication that they are meant to function with a rifle length gas tube under them, when used on an AR15. What most people may not realize is that while plenty of the AR10 barrels on the market use a standard rifle length gas tube, the gas port distance is different than the standard distance on an AR15 with a rifle length gas system.

The difference in distance is to account for the fact the barrel extension on an AR10 is longer than that of an AR15, subsequently, the gas port distance on the AR10 is shorter... to account for the increased length of the AR10 barrel extension.
