  1. I see no connection / gap between the compensator and the barell. I belive bul's material says it is one piece.
  2. Speedshooter has on stock (based on their webshop) few in short flat and short curved. Curved version seems to be similar in size to short flat if you accept the curved version. You can also buy small version and take some material off from the back of the aluminium shoe if the adjustment is not enough (on YT in one of Atlas materials it is also mentioned as option). I contacted the Geppert in germany and (mail@xline-geppert.de) and they claim they have medium and XS in stock. Mail them and let me know how it went. I am also considering to get their trigger
  3. You can ask for availability the manufacturer in Germany : http://www.xline-geppert.de/en/ There is also other shops that ship for example to europe: https://www.speedshooter.com/category_list.cfm?ID=TG&Triggers
  4. I was considering the heavy metal version but finally went with "regular" SAS II UR but without original mount to make the holes comaptible with any aftermarket optics mount and thumb rest (the original Bul mount has 3 holes only and the holes are IMHO angled not the mount). Did not see any problem keeping regular version on target its seemed to be even easier to transition from target to target. That's maybe personal preference but I have quite strong hands and it works just fine for me. Please let me know how your pistol works in the long run.
  5. Small update: After finding the shop that had the proper skills and machines to drill, tap the frame (stainless steel drilling/tapping, us tap sizes) and modify the mount I decided to make the holes in "non-bul" 5 holes pattern (0,375 inch between the holes) and US size screws (for convinience and change flexibility in the future in case of mount change). The red dot I use is Holsoun 507C (with Trijicon RMR mounting pattern) - as I see it better than other RDs due to my astigmatism and it has dot and the ring. For mount I've chosen JVIndustries mount for RMR to avoid making custom mount. It had some offset and was not exactly inline with barrel so side part of it had to be milled to center it (leaving around 0,6 mm clearance from the side of the slide) and side of the mount had to be milled to provide acess to RD's buttons. Finally after two weeks from collecting the parts I received today the parts and put everything together. Tomorrow I will be zeroing it Once more thanx for advice it helped me a lot to decide
  6. I have no intention to do it myself (although it seems a little bit tempting ) I have no skills, no tools and no stainleess steel drilling knowledge. I am asking for specific dimensions as it can be drilled only once and I would prefer to have it done right. Drilling will be done by the experienced gunsmith with proper tooling but he has no open guns specific knwoledge so that's the source of the questions.
  7. Thx for the practical advice on screws size. I will either pick good quality M3 or look for M3,5 As for holes placement if the dimensions I provided are ok or I just put the mount on the gun, see if it clears the slide and drill the holes without overcomplicating ?
  8. Hello I am new owner of BUL SAS II Open pistol that was purchased without predrilled holes for the scope mount on dust cover. I am looking for the information/advice what are the typical dimensions / location of the holes that are drilled and tapped in the frame/dustcover. I've found some info in one of the threads and would like to verify if this is correct as I can drill the holes only once ;-) I am looking for 5 holes pattern with distance between them 0.375 inch ( there will be optics mount + thumb rest on side of mount) The distance from center of the slide stop hole to center of first hole for optics mount : 0.5 inch Distance of the holes from top of frame/dust cover edge 0.135 inch All distances above assume that I will use 5-40 screws. The issue is that I am in a "metric" country and the closest metric screwes are M3 (which have slightly smaller diameter than 5-40) so I could use M4 but those are roughly 0,1575 in diameter and seem to me too thick to make holse so close to dust cover edge (dust cover is stainelss steel) Now the questions are: 1. If the dictances I provided above seem to be ok ? 2. If the M3 screws are not to weak (assuming I will be using 5 holes mount) ? Should I consider M4 screws? If that will influence/increase the required distance from dust cover edge ? 3. What should be the minimal clearance between the bottom of the mount shelf and the slide ? I am awaiting for the mount at the moment that will be used with micro red dot / RTS2 size. My concern are potential extraction/jams. I would appreciate advice. K
