I have been looking for a Picatinny gas block to mount a light onto and a magazine stock pack for my 580 series stainless. I found these pics on a gun broker listing. Can anyone help identify the manufacturer or part number of the stock pack and the gas block?

I did message the seller but have not gotten a response. |

No ideas on the pouch. The (presumably) aluminum gas block cap is interesting; haven't seen it before. How is it secured to the gas block itself? I see no threaded holes for the gas block screws, but perhaps the holes are "blind" ones. If OEM gas block screws are "staked" (many are not) strongly suggest running a die over the "staked" portion of the screw, lest the staking damage aluminum threads. If installing it, consider using 25IN-LBS of torque on the gas block screws. Some have reported an increase in accuracy with lower gas block screw torque. Keep fore-and-aft gaps between sides of gas block/gas block cap as even/identical as possible but not obsessing with perfection. If ambitious, installing a smaller I.D. gas bushing will reduce battering of the Op-Rod/receiver caused by the unnecessarily huge I.D. OEM gas bushing--same .085" I.D. as used on the Mini-30. Users report increased slightly increased bullet velocity (range) and also being able to find their ejected brass, lol. Strongly advise buying the KIT and begin by using .045" I.D gas bushing. Better a little too much force than too little force, for 100% reliability. Suggest testing in cold weather, with very cold ammo, since ammo is a bit less energetic when cold. A good many Mini users have reported very good results with this kit. |

Attached File Here is the underside of the block. I reached out to Cowell tactical about the pouch and they said this isn’t one of theirs but looks like whom ever made it copied their design. The seller doesn’t have any idea either. |

Alternative is to install Pic rails for accessory devices on sides/bottom (bipod) of fore-end of stock, which is fairly easily done with syn stocks, but not so easily done with more fragile (thinner) wooden stock fore-ends. Doing this "right" takes some effort to do so. Mini-fore-ends and gas blocks are a complicated issue. Simply put, suggest that a certain "gap" between gas block assy (or anything attached to it) be ensured in relation to "fixed" components such as the fore end of the stock. Allow for some heat-induced expansion of various components. Gas block and fore end of stock are "sliding" components, both due to heat expansion of components, as well as "sliding" being required for dis-assembly. As far as the "stock pouch" is concerned, my "personal opinion" is that such pouches very much work against using the firearm when switching from "strong-side" to "weak-side". I won't have such "stock" pouches on any of my firearms which pouches interfere with switching from right-handed to left-handed shooting. I train shooting both ways on all firearms. In some cases, I "usually" shoot Mini (and similar) left handed. Some firearms, like FAL, I shoot right-handed. Train both ways, just-in-case. Now that I have trained myself to shoot various rifles "either-hand" I find very easy to transition from one to the other. YMMV, but practice makes perfect. I get the impression from your previous comments that you are pretty knowledgeable about firearms. LMK if I can assist you. Respects. |
