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.

One of most interesting things I noticed on IWA was new 1-8x tactical scope from German company Minox.

IWA 2014 - Walther CCP

On IWA I had my first opportunity to see Walther CCP 9mmx19. Pistol actually makes good impression. Fits hand very nice, slide is easy to operate and trigger is decent.

IWA 2014 - HK news in civilian products
