Description Technical Specs
 
The KVP 40 S&W and 10mm BCG is a feature packed solution for your Blow Back Carbine or Pistol. Our BCG is compatible with Glock style magazines. The carrier is constructed of US made 8620 steel, with a Nitride QPQ finish. The QPQ finish offers excellent wear and weather resistant properties that are superior to lower grade phosphate finishing processes. We've added a beefier firing pin retention spring to help lower the likely hood of firing pin breakage. The 40/10mm BCG's feature the tried and true AR15 extractor system, which provides the needed power to pull even the stickiest PCC cartridges out.

***NOTE***
Many after market drop in triggers use modified hammers and can be temperamental in Blowback systems. For the most consistent results a mil-spec fire control group is recommended. However, in our testing, these aftermarket fire control groups should work in most circumstances: POF, Hiperfire EDT and 24 series, Geissele, Timney, Rock River, and Spikes.

.40S&W/10mm bolt May 20, 2019
Reviewer: M. Jee from Billings, MT United States  
The bolt came clean, in good condition with no discernible defects or issues. I look forward to its use.

It will however be used in a manner outside of its intended desgin for wildcatting a carbine.

Best BCG for .40 Cal July 28, 2018
Reviewer: HobbyMan  
I have tried other BCG's & the most problematic BCG's I had is the one from New Frontier Armory (NFA), just to be clear. I am not saying that NFA is not a great company, I am simply giving you my experience & that for me their BCG did not work.

When I built my AR-40 with the NFA-BCG it was nothing but cycling problems, it would not chamber the rounds & when it did, it will not go in to battery. It would also leave an indentation on the case that  looked like a smiley face.  I then I bought an adjustable buffer, started from 10oz & worked my way down to no weights, I changed the buffer spring (started with a Kaw Valley PCC XP Spring), installed an Ar-15 buffer & spring with spacer, changed the upper, changed the charging handle, changed the lower, tried every configuration until the fingers hurt.

I gave up & ordered the BCG from Kaw Valley, installed the XP spring & Kaw Valley 10oz buffer & done, had one failure to feed out of 200 rounds.
