Speed Cycling and reliability mod for Baikal MP-153

There is always that one particular brand, type or batch of shotgun ammunition that does not work with semiauto shotguns. Some shotguns are more picky than others and even same shotgun models some individual guns cycle same ammunition that other guns struggle with.

For DIY person it’s tempting to fix this uncertainty. Naturally lapping the bolt carrier rails, polishing all metal-to-metal contacts will help the gun to cycle. With gas operated shotguns drilling gas ports slightly larger might also help.

After doing all above I still found that there exists ammunition that does not cycle reliably with my Baikal MP-153.  Mostly really old 24g skeet and trap ammunition. Some may ask that why bother? Those asking that question don’t get the tickling sensation when fixing something makes things better.

Phillips head screw mod to roller cam pin

Some time ago I acquired a roller cam pin to my AR-15. Gas key had to be machined to match the new round cam pin, but that was not an issue as I had planned to give my bolt carrier some diet in a form of tender milling from my trusted gunsmith. (Final weight for bolt carrier is 173 g.)

My roller cam pin had one problem though. The screw that was supposed to hold the brass roller in place had a tendency to loosen up and then jamming itself against gas key.

Roller cam pin screw loosen up and hitting gas key. Effectively preventing bolt from opening.

Original screw was completely flat, without any screw drives. I did not had adequate tools and strong enough thread lock to hold the screw in tightly.


I contacted the roller cam pin manufacturer and they offered to fix it for me. They apparently have some adhesive to semi-permanently attach the screw to rest of the cam pin.
I, being more of an DIY-guy, opted to fix the roller cam pin myself.
After two iterations I was finally happy with the solution.

Custom made phillips head screw for roller cam pin.

It may not be the best possible steel strength for this particular application, but the brass roller leans against small bulge in the cam pin, so the screw don’t have to take any force coming from side. It just has to hold the roller in place and avoid any contact with gas key.


Time: 1 hour
Tools used: one random M4 screw, hand-file, cordless drill, hacksaw, PH2 head screwdriver and “Extra hard thread lock”

DIY Shell Prepper

Shotgun Slug and Buckshots have nasty tendency to cost much more than most smaller shotsize ammunition. This has driven many shooters to seek cheaper ways to achieve Slugshots by modifying birdshots or using the birdshot cartridge as a base and just changing the shots to slug.

I came up this brilliant idea of a shotgun shell prepper from Youtube user Mountain Storm . All credits to him for the idea.

Shell Prepper will cut the star crimp away leaving a small rim which will act as the crimp to hold the wad and slugshot in place.

Without further ado – DIY Shell Prepper v.1.0

Fixing bugs in Nextorch WL10

Nextorch WL10 is a reasonably priced, bright and light weapon light with rail mount.

I don’t go to details about the lamp itself, please refer this review

The issues with the lamp are:

  • The switch can toggle (turn ON / OFF) from recoil (or simulated recoil by slapping)
  • Sometimes the power switch doesn’t click, i.e. the lamps work only as push activated, not toggled on

Light Mount to Special EDCE

The year turns to time with less light which means some SRA competitions in the dark w/ weapon lights.

I have currently shot mostly with my custom 2011, Special EDCE, but my only pistol with a light mount is CZ Shadow.

As we all know, xx11 pistols have different grip angle than CZ, which is a problem as currently my wrists tend to turn to xx11 angle, so in the dark when you can’t properly see, the CZ points upwards if the wrists are not adjusted.

So set to enable mounting my pistol light (Nextorch WL10) to the Special EDCE. The options were to attach or machine some rail. We went with the latter.

Here are few pictures of the process:

Unfortunately the dust cover does not have very much structural strength so we had to make some compromises which makes this a custom fitting between the gun and the lamp in question. So the result is not an actual picatinny/weaver rail, only similar to.


Uudenmaan SRA Piirikarsinta II / 2016 (pictures)

Two Special Squadders and one prospect took part in Uudenmaa court SRA qualifications competition.

The weather was great for the date ( October 25th) and the stages were mostly pretty nice to shoot, with only few complaints: the plates on the plate-rack on stage1 were very heavy and it was not easy to tell a hit from 300m and 150m metal targets (stage4 and 5).

First we had to wait pretty long for the stage officials to finish their pre-match, but after that, the timetable held and we could quickly move to next stage after the previous one was shot.

After last stage we had some car problems but managed to get to awards ceremony  in time to collect the medals for 1st and 2nd in Open Division.
