Hi Everyone, I had to close shop this past month while I relocated both my business and residence from Virginia to Colorado. I've finally settled out here in the Rockies and I'm in the process of reopening CCS. I will be answering e-mails and filling orders as quickly as I can. However, I have plenty of catching up to do, so please don't be concerned if it takes me a little while to get back to you. I will continue using the same Virginia 703 859-3749 phone number as my CCS business line. However, I will be publishing a new Colorado P.O. box address soon. In the meantime, please refrain from using my old Arlington, VA P.O. box address as posted on my website. (Mail is being forwarded from my old VA P.O. box to my new CO residential address, but the forwarding process is slow.) I will e-mail you my new CO residential address if you wish to send payment via USPS money order. I am in the process of testing a new auto-loader for the BDM V-22 hi-cap mags. The design is based on the Ram-Line 10/22 loader, but with several design modifications and upgrades. I expect it will be ready soon, so please stay tuned. I know many of you are also interested in the status of the DPMS/Colt hi-cap mag project. This has been on hold for the past month while Kevin of BDM and I were both on vacation. However, I expect this project will resume shortly. Last I heard from Kevin, we may have finally come up with a workable feed lip / ejector design. Additional prototypes will need to be created and tested before we can move into the beta test phase. I will post more updates as new information becomes available. Thank you for your patience and continued support. Dan |

In case anyone needs a good CZ V-22 owners manual with an excellent schematic and parts list, I have posted a link to one in the Conversion Caliber Supply, LLC section of the Industry Forum. (Thanks to Mac in NoVA!) There are also links to several other CZ V-22 related articles that you might find helpful and informative. Please let me know if you're aware of any other CZ V-22 related articles or manuals that could be added to my reference section. Thanks, Dan |
...got it now
Yup, the DPMS/Colt mag project is still very much alive. (It wasn't dead, it was just sleeping.)  There are some design challenges inherent in this project that didn't exist in BDM's previous mag projects. Kevin told me that he first wants to try some glass filled polymer feed lip/ejector designs to see if they will be strong enough to hold up over time. We are also considering using a steel ejector insert if that proves necessary. For those that will be helping to beta test the first prototypes, we will need to focus as much on feed lip/ejector design endurance as the mag's fit and feeding function. This will mean lots of trigger time and lots of reloading. |

Hi Dan I've Had quite a bit of experiance with the DPMS/ Colt 22 conversions and currently own 4 of them, drop in and dedicated. These conversions are prone to firing out of battery with the result being the rh extractor assy being blown out of the bolt and sometimes the magazine being destroyed as well. I would recommend going with a steel insert for the feed lips. Once you get these mags up and running please contact DPMS maybe they will go back into production on there conversions as this is one of the reasons they quit making them. A solution to the firing out of battery that has worked for me is to replace the 223 recoil buffer and spring with a solid nylon 1"rod that fills the extension tube to the buffer retainer and adjusting the 2 length screws to make the conversion assy fit tight in the upper. Ihave fired in excess of 25000 rnds in one of these conversions using all types of ammo with no malfunctions  |
Hi Alpha: Thanks for your input. I also had an extractor blown out of one of my DPMS .22LR uppers as the result of a F-O-O-B, as have many other guys. I suspect this Achilles heel was the biggest factor in DPMS' decision to drop their .22LR product line. (I heard that they would be redesigning their .22LR line and coming out with some new products, but this was nearly two years ago and still nothing...) Another poster just wrote that he recently contacted DPMS about his damaged extractor and DPMS said they don't have any more spare parts available. FYI...I'm planning on having some replacement DPMS/Colt .22LR extractors made by the same manufacturer that made the replacement CZ V-22 firing pins for me. I can't afford to produce a full array of replacement parts for the DPMS/Colt and CZ V-22 conversions, but I can supply those few "weak-link" parts that most frequently break and can no longer be purchased from the original manufacturers. The fact that the DPMS/Colt mag's feed lips and ejector can also be destroyed as a result of these frequent F-O-O-B issues will definitely be a factor in BDM's design decisions. I obviously can't prevent these uppers and kits from F-O-O-B. However, I can help by offering the necessary replacement parts and a more durable hi-cap mag. Dan |
Excellent! I tried getting a spare extractor set up myself about two months ago. I was told by DPMS that they are out of spare parts and are "custom" making them if needed. If you do the extractor, would you also include the pin and spring? After my DPMS fired OOB last summer I am always a bit nervous every time I pull the trigger on my dedicated upper. Thanks! Brad |
Yes, I will also include extractor springs and retaining pins. I know from first-hand experience that OOB's often blow out these parts too. |
