FaRKle!

I got the AR10 model too. I didn't see any instructions with the packaging so I installed it a bit wrong (disconnector would catch upon trigger release so it wouldn't reset unless I manually pushed the trigger piece forward). The pull was very crisp, but I'll need to run it again to really give an impression on it.

I just counted the coils on my buddy's G2 Recon, yup 29 coils.

Probably by going AR-10 pattern and using AR-15 carbine buffers.

Looks carbine to me too.

Welcome from CA!

Got a picture of your rifle?

Compare the pistol grip area with an AR-15. The G1 has a longer receiver area behind where the pistol grip mounts. The G2 has the same length receiver area behind the pistol grip as an AR-15.

This is that barrel. It's rifle-gassed. They're emerging as a good source for accurate AR-15 barrels. Robar is using their barrels in their X7 PolymAR line (guaranteed 1MOA or better with match ammo).

As others have said before, count the coils. The LR308 carbine spring should have ~29 coils IIRC. The buffer should bottom out on the end of the receiver extension.

The CAR-10 buffer should work for you. If you feel your rifle is really overgassed though, you might want to try the CAR-10 XH. Since we know the spring is the root cause, might as well grab one of Heavy Buffers' .308 carbine buffer springs too. I wouldn't recommend trimming the spring. You don't even know if you actually have an LR308 spring or an AR-15 one. Trimming springs isn't totally forbidden though. Heavy Buffers' LR308 carbine springs are Armalite AR-10 springs that are trimmed. Yup, you suspected it was the spring, however the spring would have to be too long to prevent the bcg from travelling rearward enough, not too short ;).

I've been reading about extractor and ejection issues with the PA-10. It also seems like there's problems with it returning to battery after cycling. Unfortunately, in all the cases I've seen, PSA's taken the rifle back to fix it, but didn't really solve the issues when the rifles were returned to their owners.

I have high expectations for that barrel. Looking forward to your findings.

Excellent, sounds like we've narrowed it down to the spring then. If your receiver extension has a hole in the back, you can also confirm that when the spring is also installed the buffer isn't bottoming out by bringing the BCG as far back as it can go with the charging handle and then feeling for the rear of the buffer with a thin tool (paperclip or allen wrench work) that fits into the hole. What barrel and gas port location do you have? We can recommend the right buffer with that info. Heavybuffers also sells replacement .308AR carbine action springs.

Let's partition out the spring. Take the action spring off of the buffer, then insert the buffer into the receiver extension. Next take the BCG and push down on the hammer and slide it into the receiver extension till it hits the buffer and they bottom out inside the receiver extension. Can you push it far back enough for the bolt to clear the bolt catch (remember to place bolt in extended position)? If not, then we need to see if your receiver extension is the right depth and how long your BCG is.

Ewww Arms Unlimited. Screw those scammers.

Sounds like the standard DPMS LR308 carbine buffer weight to me. I agree it's sub-optimal though. On that note, can you hand cycle the BCG far back enough to clear the bolt catch? It wasn't clear to me from your first post whether it wouldn't lock back due to firing, or hand cycling as well.

How long is your buffer? That combo should work (assuming it's explicitly an LR308 buffer and action spring).

Probably just milspec diameter. UTG's "Pro" line is made in the US I believe. Doesn't mean I'll use them though.

If LaRue did it so can you! lol

Their Mod2 grip is my go to. I like it with the #2 backstrap.

They look different to me. The BTE looks to be an AR-15 receiver extension and the UTG looks to be AR-10 pattern. Look at the space between the ramp and the 1st position. The UTG looks larger.

So this past weekend I had a little time to function check my returned PWS MK216 rifle. I loaded up 5 rounds into the mag and began firing slowly. On round 4, the charging handle flew back and almost bopped me in the face. "WTF?" I thought, "I've never had this happen before!" As I inspected the handle I noticed that the latch lever was bent such that when it was pulled back into the recess of the handle it had enough friction to not come forward and engage the detent. I'm not sure how you'd even bend the latch without either dropping the rifle on it (there weren't any marks elsewhere on the rifle) or by placing a block on it and hitting it with a hammer (I can see this happening if it gets stuck in battery). Now I can't say for certain, but I'm 95% sure the latch worked fine and wasn't bent before I sent it off to PWS (BMoney and I were shooting it a bunch just before it got sent off and had no charging handle malfunctions). Still, I can't prove PWS may have damaged it while it was there. Anyways, I sent an email to BCM asking them if I could just purchase a new latch since the handle portion is fine and the damage wasn't due to BCM's fault. This is the reply I got this morning: Needless to say, I'm quite surprised, yet not at the same time, at extent to which BCM is going to make me a continued happy customer. Their good reputation is well deserved.

Closer to 4-5 grand... lol

Oh no, another "Cali Ed!" Haha, welcome from the Bay!
