Flatland Shooter Posted October 28, 2017 Share Posted October 28, 2017 Now if USPSA just allowed cans. Link to comment
nate89 Posted October 28, 2017 Share Posted October 28, 2017 It looks like you are using colt mags. I have the QC10 lower that I am just finishing up. Any tips/tricks specific to the colt lowers and mags you know? Best mags to buy?Sent from my SAMSUNG-SM-G530AZ using Tapatalk Link to comment
Mx556 Posted October 28, 2017 Author Share Posted October 28, 2017 Unfortunately the lower have is a standard lower which I'm going to use a conversion mag block with... Colt /Metalform mags are the way to go.. https://www.brownells.com/magazines/rifle-magazines/magazines/ar-15-colt-style-magazine-9mm-32rd-steel-black-3pk-sku078000198-57092-124271.aspx 11 minutes ago, nate89 said: It looks like you are using colt mags.

Sounds like a cool project though, looking forward to seeing how it ends up!Sent from my SAMSUNG-SM-G530AZ using Tapatalk Link to comment

Les Snyder Posted October 28, 2017 Share Posted October 28, 2017 I ran my registered SBR in a couple of run and gun shoots, as well as one USPSA match... the bolt hold open broke on the second time it was engaged on the Colt style mag... and the overall bolt travel had been reduced... don't run it to slide lock if you don't have to Link to comment

Mx556 Posted October 30, 2017 Author Share Posted October 30, 2017 Few more parts came in today expecting more this afternoon .. overall build should be about 6 inches shorter than my current PCC gun .. Link to comment
Nathanb Posted October 31, 2017 Share Posted October 31, 2017 I feel that the full size gun will be flatter. The name of the game is weight with these and the shorter barrels seem to bounce a little bit. I know my mpx does. Unless I’m running the 4.5 inch barrel with can. I’m interested to see what you find Link to comment
Sarge Posted October 31, 2017 Share Posted October 31, 2017 Out of all the majors I worked this year I only saw a few SBR’s. Must be something to that. Link to comment
Aircooled6racer Posted October 31, 2017 Share Posted October 31, 2017 Hello: We have a young guy here who started with a AR15 Hahn insert SBR and a 5.5" barrel. He buildup another 16" for the same lower and he is much better with it. He will be a Master in no time. I think 98% of the time a longer barrel will be better. Super light may not work for everyone in a USPSA pistol match. For steel challenge it maybe another story. Thanks, Eric Link to comment
Mx556 Posted October 31, 2017 Author Share Posted October 31, 2017 So I've seen a big trend in the recent months guys running super light barrel setups such as the Taccom 5.5" barrel with a lightweight extension . I don't see how I'm going to see any more or less recoil or muzzle flip from this barrel then I would one with a aluminum shroud hanging off the end of a 5 inch barrel .. https://taccom3g.com/product/taccom-ar15-ulw-9mm-pcc-barrel/ I don't see not much difference between that and what I'm building other than the fact I don't have a 12 inches rail, I know there's a big advantage having that much rail to control recoil using a C clamp style grip (which I'm not a fan of) I decided to take advantage in the fact that I already had SBR lower ,we'll see how it runs and well I do .. At the end of the day it's about having fun and if I end up with one extra gun set up that's not too bad of a downside ..;) Link to comment

It gives you enough rail to use a good grip and gives you a more compact package. My tax stamp should be here by the end of the year, we'll see how it goes. Link to comment
Mx556 Posted November 3, 2017 Author Share Posted November 3, 2017 Done, now time to test it ... Link to comment

warpspeed Posted November 13, 2017 Share Posted November 13, 2017 Well done Max - How do you like the Calvin Elite trigger ? I'm trying to justify it. ( not really ) Link to comment

( not really ) Thx had some issue with the Elite the day before the match so I decided to go with a reliable trigger I had. Need to work more with the Elite, I think I may have over tightening of the set screws when installing it. It's an extremely crisp and light trigger and work really well for about four mags then had a few hiccups .. Link to comment
