BCA side charge F Class AR

[Wolfdog91]

Hay who was it on here who used modified bear creek arsenal side chargers for their F class guns ? Remember they had them set up to single feed and had pretty good results. Had a few questions.
Thanks

I use the BCA.
Sled fed, 22 Nosler, F-Open.

Skip the gas port and associated parts for single shot play?

I ran the BCA 22 Nosler for about 3500 rounds.
No gas port and would get stickage before my 60 rounds were up.
Kept a mop handy to remove some carbon and a thin blade screwdriver handy to force the BCG back for really stuck cases.
The wife ran with gas but turned down really low and a heavy H3 buffer to dribble cases out when fired.
Most went about a foot and fell into the ammo box

AWSOME! crazy not that I got you in having problems remembering all my questions
Well one is how exactly are you throwing your round in ? Just setting them on the sled and sending the bolt home via a bolt release or are you like inserting them into the chamber ?

The gun in the video is the wife's with gas (before moving on to a Kitchen assembled Savage) .
She starts the round into the chamber then drops the bolt.
Mine was a No-Gas and stickage only comes up after 40 or so rounds, then a little mop and I'm good.
I can slow drop the bolt with a home made ambi bolt release. Hold bolt handle, flip BHO with a finger.



I replaced the No-Gas barrel with another X-Caliber with gas and no stickage.

I did have to use a spray on shim and oven/freezer to get a good thermal fit with the BCA uppers.

Ok ok that's pretty cool, so I need to have some kinda ambi deal... So was that a regular lower and you just cut the space needed ?
Also I think I've seen you talk about the thermal fittign before, in another forum but dint know if you where the same guy lol. Mind explaining the need for that a little more ? Because I think I've been building mine wrong size I've been putting areo shell sound the deal that goes into the receiver

Several methods of getting a "Thermal Fit".
My Avatar shows my "Spray On Shim".
You need to have good measurement capability to determine fit.
If you watch the video in slo-mo you can see the wife thumb the bolt release.

This thread covers how the experts put blu-gue to help with barrel extension fit in the receiver.
I put some comments in there also.

Post in thread 'Any AR builders/tuners — Lapping Q?' https://forum.accurateshooter.com/threads/any-ar-builders-tuners-lapping-q.4104142/post-38745407 Well, fabulous. I've got a bunch of 220 and 243. I'll just crank up the rounds down range to use them up:)
