New style barrel extension in HK416A5 and MR223A3

HK416A5 (and MR223A3) does have numerous changes and upgrades over older variants. Some are easily noticeable, some require closer inspection and some are well hidden. One of this well hidden differences is design of how barrel extension interfaces with upper receiver and how it is positioned.
In my opinion new method whit cut out in barrel extension and wedge on upper receiver is much better idea that classic barrel extension pin in AR15. New design is simpler, stronger, more fool proof and provide better positioning in barrel in relation to upper receiver.

Trijicon HD sights on my HK45C

Yes, I'm alive! Sorry for long hiatus, but "real life" come in way. Happens.

Anyway, Santa come little earlier this year with nice set of Trijicon HD sights for my HK45C. I used first opportunity to install them. It was not easy, but they sit in place. Then I went to verify zero on the range. On picture you can see two 25 round groups. First was on 15m (some 16+ yards), second on 25m (some 27+ yards) - I think it is easy to tell them apart on first glance. POA was top of front sight "slice" bulls-eye in half (at least I tried to keep it there). Both shot offhand with two hand grip, slow pace (and breaks to change/load magazines every 5 rounds). Looks like I need to adjust POA a little, but overall I'm really impressed with this sights. They do agree with my eyes. I will see how they work on some IDPA matches at first opportunity, but I expect them to do just fine. Previously I used Heinie Straight 8 sights, but those did not work good for me. I did not care much for dot over dot alignment and POA/POI relation was completely of for me with POI much higher than on stock sights. Finally I went back to stock HK sights. But looks like Trijicon HD sights will stay here for good. I also need to replace my aging Meprolight sights on P2000SK and SFP9-SF will need nice set of sights, when I get one in my hands.

New Aimpoint Micro T2

I just got info that Aimpoint is going to show new Micro T2 at Eurosatory fair.  It has updated body, with flip-caps, ability to ad anti-reflective device, shielded turret and increased body ruggedness. There is also new reflective coating on lenses to improve quality of view, delivers 5 years on one battery and is water tight to 25m. Basically this is all that was revealed for now. I must say it looks slick. Can't wait to put my hands on one and look trough it. (picture: Aimpoint)

Cutting HK MR223/MR556 barrel - good, bad or ugly?

There were several discussion on cutting and re-profiling 16.5" heavy match barrel that HK installs in MR223 and MR556 series rifles. Profile is rather mater of personal choice and taste, but cutting down generates some controversy. HK claims that when they cold hammer forge their barrels, they make them in way that barrel bore has a swage (constricts) toward muzzle. Barrel is manufactured for it's final length, so cutting it down remove this narrower portion and affects barrel performance. I decided to find out how it turns out in real world.

2 new 3Gun matches videos

Here are 2 videos from recent 3Gun matches. First one is Liga Sportera match, shot up to 300m at military range. Second one is 3Gun Nation Club Series rules match shot rather up close with max 50m distance. More info in descriptions for each video.

3 competition videos

I just added 3 videos from competitions in April. 2 are from 3Gun matches and 1 is from IDPA match.

First video is recent Liga Sportera match. It was not my best performance so far. Partially I blame gear (obviously! it is always gear problem!), but I'm afraid I had my own part in this.

IDPA @ Makówka - Round 1

Last Sunday we shot small IDPA match (5 stages, 62 shots) organized by TSK Ba-Bach. This is first round of series of matches aimed on revive IDPA in Poland and convince more shooters to join. Matches schedule can be found at http://www.idpa.com/clubprofile/ba-bach .

I used my HK45C to compete in CDP. I'm trying to learn shooting .45. For now I'm definitely too slow but I feel like slowly gaining confidence. I think Heinie Straight 8 sights are not best for my eye problems. I must try Trijicon HD for faster front sight acquisition.
