Flatland Shooter Posted May 6, 2017 Share Posted May 6, 2017 (edited) This got me curious so I pulled up Max's YouTube video of his Optics Nationals win. The best view seems to be right at 2 minutes into the 7 minute video. It appears Max has his weak hand thumb on top of the handguard all the way up to where the rail is cut to allow the gas to vent. His index finger is along the left side of the handguard pointed straight down towards the muzzle. His remaining fingers wrap around the bottom of the handguard. Where most carbine shooters tend to extend their grip as far out as possible on the handguard, Max is keeping his weak hand much further back. Possibly because the gun balance is so muzzle light?

Aircooled6racer Posted May 6, 2017 Author Share Posted May 6, 2017 Hello: He shoots it like a shotgun shooter does. I shoot mine the same way but a lot slower and I don't run as fast. I have never been a fan of the hold it out at the end. Thanks, Eric Link to comment
fedupflyer Posted July 12, 2017 Share Posted July 12, 2017 I cannot recommend the Faxon barrel. It has a shorter throat than the PSA barrel and both are shorter than XDM barrels. Link to comment
Ofishl1 Posted August 15, 2017 Share Posted August 15, 2017 I just built my NFA PCC with a KAW Valley Barrel.., I don't know if Faxon makes them or not, but I know it will not manually eject last round show clear without banging on the charger due to bullet jammed in rifling. I dropped from 1.110 OAL with a 115 MG down to 1.070..."plunk" drop right in...all bullet profiles end up with a ring/marks around the bullet from the rifling at anything over 1.070 ......just hoping I don't end up compressing my loads with 124g bullets...need to do some chrono work now with the mandatory shorter load required for the rounds to eject properly. My friend from our club built his NFA using a KAW Valley barrel, but...his drop test no problem at 1.135....clearly a dimensional variance between these same barrels, throat to rifling lead in...................??

MHitchcock Posted August 15, 2017 Share Posted August 15, 2017 Or a difference in bullet dimensions Link to comment

Bill I think that his specific grip there has more to do with the fact that he literally can't have his hand forward more without taking hits from the comp. If you look at older vids/AR vids he has a similar hold to a lot of 3 gun shooters. Hold out to where you still have some bend/control in your support arm. Notice his stock is out to where his grip is ergonomically unaltered. Link to comment
OPENB Posted August 15, 2017 Share Posted August 15, 2017 If have a 16" KAW & a 10.5" Faxon. Both handle rounds out 1.14" with no reaming. I've used 124 FMJ Montana Gold & 115 FMJ Hornady Link to comment
Aircooled6racer Posted August 15, 2017 Author Share Posted August 15, 2017 Hello: I have seen some barrels that will take loading long right from the factory and others that need throating even from the same make of barrel. I have not had any problems with the Wilson Arms barrels or the JP for being able to load long. Thanks, Eric Link to comment

Its a damn 7" barrel with a 9" "muzzle device" (basically a shroud that serves NO FUNCTIONAL PURPOSE other than "legality") and they want almost $200 for it. They are out of their damn minds. So that was the first design......who is this clown??? The second design....the one we are selling now is a 5.25" rifled barrel with an aluminum shroud that is pinned and welded. Total weight is 15 ounces. Yep....it's total competition. We did do a chamber that will allow for longer bullet profiles too. And reduced the cost as well. Link to comment

Hello: It could be a show stopper if you need to load longer for better feeding or the factory ammo does not fit the barrel you have. Just what I have seen here. Thanks, Eric Link to comment

Thanks, Eric Yes and a solid observation, ..and apparently a chronic mfg (or standard dimensioning for KAW) condition, just returned the KVP Barrel to JBOB, they sent another ahead in 2 days of my providing depth gauged dimensions of the chamber and bolt face using our Aero-Space lab,.. which may not have had any value with no baseline dimension provided back to me for determining a Go-No-Go barrel......no other questions asked, barrel showed up quick, measured and plunked, a twin to the one I sent back.........so I installed and tested, ran like the other one with a couple of cases that didn't clear the eject port and rattled around in there while the next round tried to load...this is new but was not chronic, 2 times out of 50 or so rounds, but still not happy to load this short, I am not confident of running it in the State PCC Champs next month, I think another barrel has to be bought from someone else..then I will have the KVP barrel reamed by a smith for a back up or another build, its a shame I really like the profile and weight of the KVP barrel,...but has to be consistent. So far have not seen anything like it.. yet. Link to comment

Hello: Since you have an Aero Space lab get them to turn down a Wilson Arms barrel to the same profile as the KAW barrel for you if you like the weight of it. For me I have found that you can go to heavy and also to light for an upper assembly. The timer and target are the best test. Bullet weight and profile are a factor as well. Lots of good smiths in Arizona so you can get that barrel throated. Thanks, Eric Link to comment
wyliearms Posted August 25, 2017 Share Posted August 25, 2017 FYI - Any PSA barrel made after 8/1/2017 has been lengthened to accept longer chambers and the chamfer has been redesigned to aide in feeding issues. The barrel will be labeled "9mm PCC Chamber" near the muzzle. If you have a PSA barrel and are having feeding issues you can email customer service and get an RMA to have it replaced. You would be surprised how well it runs. Link to comment

Thanks, Eric Our Lab is for receiving inspection of parts from our suppliers, we have precision gauging systems but we do not do any machining unfortunately. I did run the 2nd KAW barrel today with various profiles, and "short" lengths loaded to an avg 1.060 on Frontier FP 121g, 115g MG RN, 124g Delta HP, 121g MG IFI, of all these the Frontier 121 FP and MG 115g ran perfectly at 1.060, Deltas were actually at 1.080 and misfed a few times,...interesting point of ref to the Factory OAL on a Amercan Eagle 147 g Flat Point OAL out of the box is 1.060. So all this discovery and chrono work shows the shorter OAL and the same charge did not change the PF enough to make any noticeable difference, regardless, on a recommend from AIRCooled have ordered a Wilson A. 16 inch SS and will go through the dimensional pre checks, if it will carry the desired longer loaded OAL ..then KAW comes out and will find a smith to Ream it for another build or back up. JSE Surplus price was fair enough at $130 and checking the weight it is only 3 oz heavier than the KAW, likely not enough to notice...will report on it in a few days. Link to comment

Hello: When you get your Wilson Arms barrel you can turn off the sight boss it has on it to make it lighter if you want. I have done that on my barrels to make them like a JP barrel profile. It works great and you can add weight or make it lighter by your hand guard choice. Finding the balance that works for you is the key. Thanks, Eric Link to comment

Thanks, Eric Hi Eric, I just received the Wilson Arms SS barrel tonight, and it is a nice barrel, all be it a little on the heavy side as you mentioned earlier, not a great deal more than the KAW, published spec between the 2 barrels is 4 ozs, will have to weight them both when I pull the KAW off my NFA... and to confirm OAL tolerance of the new W. Arms..I drop tested various lengths up to the longest I had loaded at 1.125 and it spun freely...AT LAST!! I am excited to install it and test...I would love to have it turned down some like you did, but my Smith is gone to compete in the World Shoot and the AZ State PCC Champs are in 30 days, need to settle this gun down with a good barrel and practice, practice..so I am going with it as is for now. Thanks for all your solid recon on the barrels...good info. Eric J Edited August 31, 2017 by Ofishl1 pic Link to comment
