It has been more than five years since I took a chance on a Palmetto State Armory nitride finish barrel for Kaylee.
I have definitely not shot it enough to wear it out, but it, likewise, has not suddenly failed for no reason.
I've liked it well enough that all the 5.56 mid-length guns are running PSA nitride "Freedom" barrels. 4150CMV, 1:7 twist, 5.56x45mm chamber; winning.
As a matter of fact, the only barrel purchase since I changed to nitride that wasn't PSA or nitride is the 20" gov't profile barrel for the A4 clone from Brownells.
That one is 4150CMV, chrome lined and parkerized. But for a clone, it needed to have a particular finish.
1:9 is running kind of thin lately too. At one time 1:7 twist barrels were hard to find and cost a premium over the 1:9. Now it seems to have become the standard.
Something else that used to be cheap was 1:12 20" pencil barrels. Retro demand sent those to the stratosphere. Vintage barrels are getting very expensive and the repops have several farbs which tick off the purists. I had to resort to a repop for the M16A1 clone.
At the risk of being one of "those guys", let me recommend you take a look at Faxon barrels. They make many different versions, but I'm speaking specifically about their "Match Series" AR barrels. I have a 16" gunner profile barrel with a 223 Wylde chamber. It is nitride finished (yes; inside & out). I cannot say enough for the quality. They're neither the cheapest nor the most expensive, but BOY do you get quality-for-money!
ReplyDeleteI set out to build the light weight patrol rifle I wished I'd had in Baghdad while in uniform, and this is the barrel I chose. I still would. With the one caveat that it will probably show loss of accuracy were you to get in an hours-long firefight, this seems to me to be the sweet spot between weight and heat tolerance.
....just my opinion & worth all you paid for it.
IIRC Faxon never has what I want when I have the money together, so I end up at PSA because they have it in stock.
DeleteI'm not opposed to them, we just never seem to meet in the middle.
