steve-o 1963 Posted May 16, 2012 Report Share Posted May 16, 2012 Hey everybody. My name is Steve Ward and I'm a new member as of today.Recently I purchased a BM62 in what appears to be the Mark1 configuration. It has the tri-compensatore with the bayonet lug deleated. I just bought a para tri-comp from Standard Parts and have been trying to work through some issues with Greg relative to fit.It appears that the para unit has a deeper thread depth than the Mark1. If I screw it all the way down and then back it off slightly to install the gas plug. it has drawn my gas block forward by about 1/8" almost enough to allow the operating rod to fall out. It actually did fall out enough to lock the bolt open once.I reinstalled the Mark1 unit and it pushed the gas block right back into place and the gun fired normal.I figured out that if I thread the para unit down to where the Mark1 unit meets the gas block and installed the gas plug, it fits well and does not move the gas block out of adjustment.I plan to test fire the gun today after work.I have encountered a different problem though also. Now the grenade sight will not fully index in the upright position. The sight is now contacting to back of the para removeable section just enough to keep it from being straight up.I have realized that the Mark1 type has about 1/8" of extra material in front of the threaded lug where the lug and the compensator are seamed. The lug on the para comp is minus that small amount.SOS....I need help from the BM59 efficianados. This gun has been on of my bucket list guns for 25 years.It is a correct gun, PB barrel, PB everything.Best, Steve Link to comment Share on other sites More sharing options...
winbar Posted May 16, 2012 Report Share Posted May 16, 2012 Hello Steve,I'm trying to attach a picture of my select-fire with the quick-detach installed. I have 3 QD flash hiders and 2 mounts. Sarco had a QD that had not been demilled on their website in April 2001 and I was lucky enough to get it. The quick detach collar has what I guess are 2 tensioning cuts: one on top and one on the bottom. The collar on my issued QD is pinched in on the lower cut and allows the GL sight to almost hit vertical. I am guessing unless they made a slightly altered unit for the QD flash hider, they put the grenade sight up,dropped the QD on and smacked it with a mallet to get a "custom" fit.Doug Link to comment Share on other sites More sharing options...

steve-o 1963 Posted May 17, 2012 Author Report Share Posted May 17, 2012 (edited) Doug, Thanks for the quick response. I tried firing the gun last night and it still will not full cycle. It will fire, eject, but not travel long enough to strip another round from the magazine. My problem doesn't apper to be anything any of the adjustable gas plugs will address. I'm not making enough pressure. I don't understand how to create more pressure, or why the change to the para comp causes this issue.If I back the threaded para lug off by one full turn and then install the gas plug will this push my gas block tighter causing greater gas pressure that I need?Additionally. The two halves of the compensator fit very loosly. I see a 1/16" deflection at the muzzle end. I'm concerned about shaving. Do they just fit this loose, and could this contribute to the low gas pressure. I would be willing to buy another from a different source that fit and presented better than this one. Any leads on that?The gun fires so beautifully with the long one peice compensator, but I really want that para QD comp on my gun.I really need help on this low gas pressure issue. I was really hoping there would be a dozen different responses when I opened the site this morning. Should anyone wish to contact me directly, please feel free. Steve @314-226-3857, or labadiearms@aol.com. Edited May 17, 2012 by steve-o 1963 Link to comment Share on other sites More sharing options...
winbar Posted May 17, 2012 Report Share Posted May 17, 2012 Steve,I sent an email directly to you. The paracadutisti tricomp requires a special barrel that leaves the barrel's muzzle protruding about 1/2" beyond the end of the gas lock. (I'll try again to get a pic with my explanation.)There are posts here from a few years back where guys have blown the tricomp off the barrel because they don't have the muzzle protruding and sealing with the QD tricomp.You may also get cycling problems by not having the gas cylinder aligned properly with the barrel gas port. MY barrel is a modified tanker barrel that I ran the gas lock threads back on with a 9/16" x32 tpi die,relocated the gas port hole and gas cylinder slots, so I could run the quick detach setup. I use a large paper clip that is bent up to locate the gas cylinder so that the barrel port is centered in the gas cylinder expansion chamber.My barrel is a home-made job, but your PB barrel should have the gas port centered with the gas cylinder as far back on the barrel as it will go, screwing the tricomp down to contact,(on my PB barrels the tricomp goes less than 1/2 turn past alignment for the gas plug), backing the tricomp off to align for the gas plug and tightening it very tight with a hex head wrench.Doug Link to comment Share on other sites More sharing options...

ordmm Posted May 17, 2012 Report Share Posted May 17, 2012 (edited) Steve, This pic should illustrate the differance in length between BM62/BM69 and BM59 barrels. Can't say which models of BM59's used the barrels with the longer muzzle but would have to think anything with a tri-comp or para type brake would require the longer barrel. Trying to figure what used on what rifle is made a bit more confusing by the fact the Reese probably used just about any combindation of parts on the rifles they built. Add in homebuilts that are pictures on the web and it gets crazy trying to figure out what was used on which rifle originally. On one of the shooter rifles I have it was necessary to soak the brake and barrel threads with Kroil to get the tri-comp to spin off. The ammount of carbone build up was very surprising as it extended into the grooves in the pic. Guess it would be pretty good evidence of the back pressure these brakes produce. Anyway, would agree with the other poster that your taking quite a chance firing thru the longer brake. Would be very concerned with a bullet strike. I would urge anyone not to take the issue of a bullet strike lightly. Offer still goes, return the brake, no problems at this end. When we discussed the issue don't think you pictured the differance in muzzle length I was describing. The pic below should help.

My "correct" length paracadutisti barrel would be even with the lowest ring of your 5 ring barrel. I put my quick detach on the 5 ring barrel and the sleeve in the tricomp is so long that the barrel does not protrude into the first (booster) tricomp chamber. So it should work without affecting the tricomp's performance. I don't know why they made the 5 ring, I thought maybe they decided to extend the paracudisti barrel for some unknown reason: better accuracy or comps blowing off with the shorter first version. (Never happened to me though) Also my "correct" paracadutisti barrel and my "5 ring " were both made by Silma in 1970 so go figure. Link to comment Share on other sites More sharing options...
steve-o 1963 Posted May 18, 2012 Author Report Share Posted May 18, 2012 Greg, I will not post your actual response that you sent me. It was foul at best. I respect that your not a gun smith, but you sell to the general public as a "gun parts dealer". I have sent you two e-mails that have now been returned, and we have talked personally.Both of my e-mails have been returned as a failure, where they weren't before this incident. Had this para comp caused me harm, or death.....it would be a very bad thing for you and your heirs. Product liability is a major issue when selling "GUN PARTS". Knowledge of your parts is foremost when "generally" advertising a part as a "bolt on". There is no disclaimer addressing the fact that this part may or may not work on certain barrels.I read just fine. That was not in the print, or the small print.But for Doug telling ,me not to fire it again....I'd still be trying to figure out what you should have known and informed me before advertising this part without any disclaimer. I have children that shoot regularly with me on weekends. Do you understand where I'm going?Consider your ill response and lack of customer support a God Sent that nothing bad happened in the mean time.Had as little as my dog been shaved by a round from this para comp, we'd be talking through lawyers.You have my phone number and e-mail. Use it to rectify this issue.I will post the actual chain of e-mails should anyone doubt the manor in which I was dealt.You chose this format to respond to me, so here we are.Make things right, not throw salt in the wound.

ordmm Posted May 18, 2012 Report Share Posted May 18, 2012 WOW! Guess we quit sellng parts. My apologies to anyone on this site who I pissed off. Won't happen again. Greg Link to comment Share on other sites More sharing options...
bm59collector Posted May 18, 2012 Report Share Posted May 18, 2012 Steve-O - I'm heading to the BMW bike rally in Sedilia at the fairgrounds in mid July (weather permitting), you anywhere near - if you are, I'd sure like to stop and talk to you. - Regards, Art Link to comment Share on other sites More sharing options...
steve-o 1963 Posted May 18, 2012 Author Report Share Posted May 18, 2012 Art, A BMW bike and BM59 owner, hell yes! I may just come to the rally if I don't have any conflicts with work travel.I sold my 1991 GS100PD here a few years back when I fell on some hard times. But I looking again.Your more than welcome to stop by though. The town of Labadie is a great detour for motorcycle riders. Highway T which I live on, is on the BMW Ultimate Drive app. I've posted it myself. I have 11 acres of forest and a great place to shoot.I listed my contact information above when writing to Doug. Feel free to write or call anytime. Best, Steve Link to comment Share on other sites More sharing options...
ordmm Posted May 19, 2012 Report Share Posted May 19, 2012 (edited) Don't mean to poke the bear with a stick ...so to speak. But we are out of para brakes and tri-comps. Please no more emails. Only had one barrel and it's gone. Am working on getting the pickers to give up another stash for whiskey money...but unless Steve wants to sell you his...we are out. Thanks for the emails on this, but at this time it looks like there are no more brakes to be had from our sources. Only in America! A bit of negative press turns into a very nice sales event! Best regards. Greg Edited May 20, 2012 by ordmm Link to comment Share on other sites More sharing options...

hawksnest Posted July 19, 2012 Report Share Posted July 19, 2012 (edited) I just purchased a full length para tricomp, complete with para QD lug. The para tri-comp is marked "PB-BM59 pc". The QD lug is marked "PB" on one side and ""BM59-pc" on the other side.The barrel in my BM59 is not the right length (too short). So, I can't use the para tri-comp.. Anyone looking for a complete para tri-comp send me an e-mail. hawksnest12@embarqmail.com Edited July 19, 2012 by hawksnest Link to comment Share on other sites More sharing options...
