    First off, this is the original review of this rifle when I first purchased it.

    http://www.snipershide.com/shooting/showthread.php?t=76978




    The rifle started life as this, a 40-XRBR:

    I put it in this:

    And now it resides in this:

    (link to progress of conversion and who did it)

    What this rifle is capable of:

    2pr7877.jpg




    SO, I hope accuracy has not dropped off!! I have also had the barrel threaded for suppressor. Still on the fence with rimfire accuracy and suppressors.

    Will update post as I do more ammo testing. Last round of testing I actually settled on Lapua Center-X. Love that stuff. But I also used to be able to get it for $90 a brick. Now I cant even find crap Rem ammo for that price!!

    Its early so these are preliminary thoughts on the process

    POSITIVES:
    -Having a repeater
    -Workmanship. Very clean cuts and overall nice work. No half ass shit here.
    -Mags fit all bottom metal that accepts AI mags
    -Did I say having a repeater action that will fit in any Rem 700 stock?? very cool

    NEGATIVES:
    -I would like to say wait time, but in reality, it only took 8 months. Since the beginning I told myself a year is when I would get irritated. So plan accordingly.
    -Plastic Mag. I hope there will be no issues with the mag catch getting rounded off or anything, but with plastic mags, I can def see this happening. That was the reason that my smith for my Anschutz 1407 conversion would not make me a 10-rnd mag (they made out of plastic and would not last). Time will tell. I am sure Mikie Bush would take care of it though.
    -Price. The $495 plus $38 for a mag seems high to me initially. Guess thats the price for being cutting edge :)

    Again, these thoughts are very preliminary. If you have any specific questions, let me know. I will be adding to this as I get more familiar/testing with the rifle.

    Regards,
    DT

    Glad that you put the price in there, as I was curious. Very much considering doing one of these in an AX chassis, as a trainer for my AIAX. What barrel is it you have on it?
     
    Great to hear it made it back DT. It does look like good work. I expected the mags to be metal and I thought one was included in the pricing?

    What is the "scuffed" area on the back of the bolt in the first pic? Optical illusion or was some machining done there?

    Also, in the second picture, it looks like the bolt shroud has a line cut into it. Was that purposely done?

    Congrats bud. After all the talk you were braver than I.
     
    Is the action bedded? Very nice, thank you for posting. Looks like a very good shooting rifle. Center X is bad azz.
     
    That does look like awesome work, thanks for sharing!

    I assume that the conversion was done by Black Ops Precision, but the OP can correct me if I am mistaken.
     
    495 + 50 per mag..... Pfffff. That's nothing, especially if it can shoot. I looked on their site for price. I guess u have to call n get a quote?

    The barreled/action is a Remington Custom shop product. Not sure on which barrel they use.

    so did I. Will have to look at back posts to see if it was just a mistake.

    optical illusion?? ha I not sure

    Also, in the second picture, it looks like the bolt shroud has a line cut into it. Was that purposely done?

    Yes sir I believe that was purposly done though I am not sure the reason. it was like that from day one.

    Congrats bud. After all the talk you were braver than I.

    Am very excited to get this back and start practicing. It seems more and more rifle competitions have shooting in/through some kind of barrier, so I def need to hone my skills. The rimfire will be nice, not only for cheaper ammo, but the similiarity to my match rifle.

    I would say either email or PM here. I added link above. He posted his price I believe in the thread.

    Do you think that group (in your comp target) is typical of the performance with good ammo? If so, that rifle shoots fan-fucking-tastic. Eyeballing it, it looks like a low .2". Which is why I asked about the barrel (the performance indicates the custom shop uses good barrels.)
     
    Wow
    Did not know you chopped a Rem Custom shop rifle! Damn. You did want a repeater.

    Got a close up of the bolt face?

    Smag~
     
    Shoot that thing yet? Don't tell me a little snow kept you from shooting it this weekend!

    If I read it right than that Tactical Target is from before the conversion that he posted for comparative purposes when he shoots a new target. But my 40X shoots the same if I do my part right with the same ammo! Center-X!

    Looking forward to seeing how it performs, wouldn't mind sending mine in once the weight time dwindles down.
     
    Weather been so crappy seems like snowing every weekend.

    BUT I did get to shoot on Easter. Winds gusting from 5-15, so I didnt get to really check it out group wise, but it shot/cycled well. So instead of dealing with groups or anything, I was checking dope to 400 yds. Ha with that wind I was holding 3 mils at 400 yds, and was missing either mil left or mil right shot after shot. Did get a coup hits though. Only shot 10 times at that distance.


    overall, that conversion works flawlessly. Being a natural pessimist, I tried several ways to make the cycling fail. Only way I could is to put pressure under the mag (forcing it up). this caught the bolt several times (not allowing bolt to close). Other than that, it worked surprisingly well.

    The only modification to the bolt was opening up the bottom of the bolt to fit over the mag lips. Will get a pic up. this bolt fit in my other 40x but my other bolt did not work in this obviously.

    Overall, I still find it weird not having to single feed! its like my hands are on auto pilot after every shot and I had to make a conscious effort to keep hand on bolt and just cycle it.

    Will get some group pics up once the weather is more agreeable.

    I expected the mags to be metal and I thought one was included in the pricing.

    The magazines were not advertised as being metal. The mags shipped with the first few conversions are molded from a PolyCarbonate material and the material used in the "production" mags is a Glass Filled Nylon Composite (much like the AICS .223 mags). The PolyCarbonate mags in the hands of the first few customers will be replaced with the production mags.

    What is the "scuffed" area on the back of the bolt in the first pic? Optical illusion or was some machining done there?

    Not part of any BlackOps work.

    Also, in the second picture, it looks like the bolt shroud has a line cut into it. Was that purposely done?

    This is a "take-down" slot as supplied from Remington. The idea is to pull the cocking piece back far enough to stick a penny in the slot and disassemble the bolt. These slots were present in the older Remington cocking pieces.

    I appreciate Dorgan taking the time to post his experiences with what has led up to his returned and converted 40X. I'm astounded by the level of interest in this system and after the challenges experienced over three plus years in getting it finished, I appreciate the patience within the community.

    The delivery times are quite a bit shorter now. The hold-ups with the initial conversions was largely due to the patent process, as its quite apparent that R&D stands for Ripoff and Duplicate within the Gun Industry. Most say the Chinese are the worlds worst at this, but I think the gun industry could give them a good run for their money.

    Another challenge has been the injection moulding process. I paid $60,000+ for the set of moulds to make magazines, and there's been quite a bit of fine tuning to the moulds involved, which of course continues to drive up the cost of the moulds. We have the issues with runner and gate placement resolved and will be moulding magazines next week using the Glass Filled material. I'll make every assurance that there will be no wear issues related to magazines when BlackOps Precision performs the conversion.

    Future conversions will receive a BlackOps bolt nose. The Remington bolt noses are incredibly hard and we go through a lot of tooling to carve on them. There's a significant difference between what the bolt nose is after the conversion, as the feeding, extraction and ejection cycle has to be tuned properly. Yes, the bolt nose has to slide over the magazine, but there are numerous other subtle changes as well. The bolt nose that we supply with the conversion is the same bolt nose used in the BlackOps Model 605 Rimfire Repeater.

    Thanks again guys and Dorgan for posting. I'll be available for questions/comments via email or at the shop. I haven't been successful in receiving or sending PMs since the changeover.
     
    Thanks for clearing things up Mike. You got a good thing going here and I know you will have many more satisfied customers (as soon as they realize Rome wasnt built in a day! :D) This is the rifle industry, not fast food.

    Also wanted to make something clear. I dont think alot of people realize you are not a rimfire specialist. You do ANY rifle builds, so the wait times arent necessarily on a rimfire in front of theirs, but others full rifle builds.
    Best advice: Get your rifle in the work que ASAP!!!

    Mike - what is the status on the sporter repeater conversion?

    The Sporter Conversion has been pushed back a bit. We're getting our Centerfire Bolt Actions into production (along with the Rimfire Repeater Bolt Action), so I won't have the bandwidth to focus on the Sporter Conversion until late 2013/early 2014.
     
    Mike,

    lead time on a 40X conversion? Have barreled action with a PT&G bolt/Rock Creek barrel, would you need to change the nose out on the PT&G bolt?

    Deliveries on conversions right now is about three weeks with current supply of magazines. No need to swap out the PTG bolt nose. We'll machine it as part of the conversion.

    Overall was a good day. Shooting the Ruger Rimfire Challenge this weekend, and doing the long range side match as well. Should be a good time. Will keep yopu updated of the results. Let me know if anyone here is going to be there, I will be happy to let you shoot this beast. I will be shooting in the Friday squads.

    Thanks for the follow ups D_Tros. I can't wait to get mine. It will be in an AICS chassis to match my center-fire Mike built for me.
     
    Very cool. Keep us in the loop with any updates on this rig. I am seriously contemplating doing one.
     
    D_Tros,

    thanks for the update. I'll get a hold of Mike on Monday and send my barreled action out. Hoser's might be right behind me.
