Experience with Lead Star 9mm lower

Has anyone used a Lead Star 9mm lower for some time? What was your experience? Did the feed ramp really make a difference? Or would you chose a different lower next time?

 

 

Well, as far as I'm concerned the feed ramp is worthless, especially if you want to shoot JHPs with a TC ogive.  You'll have no issues if you shoot round nosed bullets.  Also the LRBHO on mine broke the first month.  I don't know if it was because I short stroked it or what.  Other than that the quality is great.

 

I bought a complete Leadstar Prime 9mm PCC because I wanted one in a hurry.  I didn't want to experiment to find out which pieces worked well together.  A shooting buddy shot on for a season and a half with zero malfunctions.  That decided me.

 

If I was going to build one myself with parts from various manufacturers, I'm not sure I would start with a Leadstar.  I think I'd pick something that used an AR-15 mag so I could use it with Glock 9mm mags (with adapter) and 22 lr mags.

I had a Leadstar and it shot very well and seemed to be good quality. I only shot round nose, so I can't say a ton about the feed ramp helping or not. I am now on a team sponsored by JP and switched to a GMR-15.  I am extremely happy with the JP. It is smooth and fast, and has been 100% reliable. JP doesn't use a feed ramp if that helps with your question.

Leadstar arms all the way. It is light but not to light. Comes ready out of the box minus optic and a magwell. Thousands of rounds through mine and malfunction free. Feed ramp lets you run flat points problem free though I do RN. The last round bolt hold open is not something I really worry about as I shoot more USPSA than the 1 IDPA match a month.

Thank you very much for the responses. I get the feeling that there really is not much enthusiasm for the Lead Star lowers.

 

 

The only problem I have with the Leadstar is feeding certain brands of factory JHPs with very wide openings.  They hit the feed ramp and jam.  It works perfectly with my reloads using PD, Everglades and Montana Gold JHPs.  As far as the LRBHO not working, I may be wrong on that.  I just remembered that I'm trying out a new JP polished carbine spring.  It is considerably longer than the one that came with the gun, so it may be stacking before the hold open can engage.

 

If you intend to build a PCC with components from various manufacturers, my suggestion to consider an AR lower was so  you have flexibility.  I cannot put a 22LR upper on my gun.  I could if it accepted AR-15 mags.

Thanks for the link. Really nice looking stuff. Do you know if the additional charging handle is reciprocating? 

 

Yes it is  reciprocating.   I have one of the first ones made.  Probably 30K plus rounds through it and it is running strong.

I know the owner/engineer who designed the PCC.  Pretty smart guy.

If you have any questions, let me know. I've shot them for years and have great success with them. They are pretty heavily used in both Steel Challenge and USPSA with a proven track record. 

Thanks for your kind offer.

I was wondering whether Lead Star did a good job designing the magazine well, correct feeding angle and internal dimensions. I am aware that JP and QC 10 did a good job, there lowers just do not have the features and price I am looking for.  

I feeling more comfortable with Lead Star now.

Is there a magazine adapter for Glock magazines that you would recommend?

No problem with any of that.  I even run the 40 round ETS mags with zero issues.

I have no personal experience with any of them, but Stern Defense comes to mind.  https://getstern.com/mag-ad9/

A Lead Star matching upper / lower receiver set was used as the basis of my 9mm build.  It has been very reliable and the tolerances are extremely tight.  Bullet profile is 147 Truncated Cone from Blue Bullets for USPSA and 105 Bayou for Steel Challenge.  It also ran Montana Gold 147's very well.  Yes, the ramp is very helpful with the bullet feeding as this particular barrel does not have a pronounced ramp.

 

Smoke Composites provided the furniture and the barrel is from Bobby Keigans at CK Arms.  Wanted the barrel to match the backup gun, just a bit shorter.  The trigger pins have never moved as the hole to pin tolerance was VERY tight.  Sig Romeo4S and Crimson Trace riding on top and a HyperFire gets things moving.

 

The Glock magazines were very tight going up into the bottom of the Tac-Com bolt carrier and each of them had to be slightly shaved until the metal lining was even with the top of the plastic.  The MBX steel magazines did not have to be modified at all and with the extension, will run 48+ rounds quite comfortably.
