  1. I have always like the M4 Entry. The c-stocks are nice on an SBS. Hello, SD, it's been awhile !
  2. Carry on. Just experimenting with photo uploads on the new site format.....much improved.
  3. It is quite simple. IF you are purchasing the firearm from a reputable FFL in the locale of your domicile AND you personally don't have any legal liabilities from owning such firearm, no problem. IF you source the firearm from a non-FFL then you are responsible for knowing all applicable the Federal BATFE laws as well as the State / Local ordinances that apply to firearm sales, the most restrictive of the collective laws controlling its ownership legality in your locale. All the laws are now readily available for review at the click of a mouse.
  4. Hammer cocked and locked on insertion of the trigger group?
  5. Maybe the detent / spring are just full of crud and they and the channel that retain them may just need a good cleaning to allow the detent to have free full travel to engage the handle. Collectively, all the parts involved are a few bucks total. IF one desires a different handle, buy the parts and swap them out and see what happens. Carry on.
  6. My Plan A would be to gently open up / deepen the handle component and see if it helps. One can remove the bolt and insert the handle and observe exactly what the situation is. In my view the detent-handle engagement of the axle component of the handle is a non-load bearing surface that simply retains the pin in its lateral position thru the bolt; the actual axle of the handle bears all the load with retraction of the bolt, however its only with hand pulling rearward force, not a repetitive high speed violent impact on the axle part. So I don't think the surface hardening is particularly important at that engagement site. One only has to deepen one of the surfaces not both on the Carrier Comp; the G&G "spinner" however is a continuous circular detent. Due to part intolerances, the tip of the detent may not be engaging the handle recess correctly. Plan B addressing your correct observation about the limiting travel of the retaining pin, would be to fill in the handle recess with some JB weld, then incrementally enlarge the engagement until it felt like a solid fit.
  7. And finally, you might take a small round needle file and deepen the notch where the detent engages it.
  8. The 14" entry M4 has a smooth bore fixed Cylinder choke barrel.
  9. Doesn't anyone pick up a cell phone and call a business anymore ? Seems as though a recording of "This number is out of service" would be a more immediate concern and unanswered / delayed email messages.
  10. The "A" series of dating the Benelli's used 16 second letters in their codes, "B" series used 15 second letters in the codes, skipping some letters (highlighted) that have also been skipped to date in the "C" series of date coding. The "CS" would be a 2017 mfg. date code if the C series is going to follow the template of the B series coding.
  11. From the back of my load-out room a very rare M4 All Tactical limited edition. ACOG 6x48, RMR for inside 50 meters and Barry Dueck Offset BUIS.
  12. From the Benelli M1 Manual: Extensive testing in ballistics labs and repeated field-testing of our line produced weapons put at 180 kgm the lowest level of kinetic energy that must be generated by the cartridge 12 gauge and at 125 kgm for 20 gauge to fully cycle the action (the measurement was taken on a manometric barrel, according to at a velocity of V1 at 10 meter distance from the muzzle). Empirically, Benelli has determined the minimum threshold of kinetic energy required to cycle the bolt; the rest of the understanding is simple mathematics / physics. See thumbnail. KEMin = ½ m VMin2 KE=kinetic energy m=mass of gun V1 = Vmin = minimum cartridge power to cycle M1 action When the mass of the gun is increased = m2 ; V2 will be LESS than V1 Because V2 is less than V1, the minimum amount of kinetic energy to cycle the inertia bolt mechanism is not generated. The Benelli M1 20 gauge inertia bolt weighs 385 grams. Two 20 gauge cartridges weigh 65 grams Two shot magazine tube extension weighs 300 grams Total = 365 grams So, a 2 shot extension tube with cartridges is within 20 grams (2/3 of ounce) weight of the inertia bolt weight. The attached may assist in understanding how adding weight / mass to the inertia platform may interfere with reliable cycling operation. The 20 gauge M1 bolt weighs 385 grams; a 2 shot magazine tube extension weighs 300 grams Plus 65 grams for the 2 cartridges and you have 365 grams of extra weight; almost the weight of the bolt. Third parties cite Benelli sources as stating that ~ 500 grams of added weight (1.1 pounds) begins to reduce reliable function. A 12 gauge 2 shot extension and two 3" cartridges is just about 500 grams......again, just about the mass of the 12 gauge inertia bolt. So, the addition of the 2-shot extensions plus the cartridges do not exceed the bolt weight, but add a Picatinny rail and a light etc......therein the problems of operation may begin to be experienced.
  13. I just checked. I bought the Geissele hammers for $50 in 2013.
  14. The Geissele hammers are like fine vintage wine.....year matters. I might let this one age a little more at this $ pace.
